Description

Advanced treatment system of wastewater and wastewater

The present invention relates to an advanced treatment system for sewage, wastewater, and sewage, which will be described in more detail. The anaerobic and aerobic environments may be repeatedly or selectively formed from influent sewage and sewage to decompose organic matter, nitrify and release phosphorus. In this way, through the inherent carriers through the inherent carriers, the adsorption and filtration are used to decompose the hardly decomposable organic substances so that they can be reused in toilet water, sprinkling water, landscaping water, etc. The present invention relates to an advanced sewage treatment system.

Recently, the demand for water is rapidly increasing due to the industrialization and the improvement of living standard, and the demand for reusing water, living sewage, and factory wastewater is suggested to secure alternative water resources in the situation of deepening water shortage. Accordingly, the government is mandatory to introduce a heavy water facility to buildings that use a certain amount of water, and thus the need for technology development regarding water reuse is increasing. Here, heavy water means that water of water quality suitable for each application is not necessarily required as much as that of drinking water among many waters which are conventionally supplied by constant water. For example, for flushing toilet water, sprinkling water, and landscaping water, the criteria for residual chlorine should be detected and should be 0.2 mg / L or more. In addition, heavy water quality standards are proposed for each application in terms of appearance, turbidity, BOD, odor and pH.

On the other hand, as the water reuse treatment technology as heavy water, Korean Patent Publication No. 94-3872, "Sewage dewatering reuse apparatus", Korean Patent Publication No. 97-20963, "Water treatment system using membrane treatment and its operating method" And Korean Patent Publication No. 1999-33044, "Flow Control Aeration Tank and Ultrafiltration Membrane Water System."

As such a prior art, a biological treatment method (system) will be described as an example. Firstly, wastewater is first screened to remove coarse particles, and then a technique of dissolving organic matters in a biological treatment tank and discharging them for various uses is commonly used. Here, the biological treatment tank is generally composed of an anaerobic tank, an anaerobic tank, and an aeration tank. The wastewater and wastewater introduced into the anaerobic tank are decomposed and removed by methane gas and carbon dioxide by anaerobic microorganisms, and the accumulation of bacteria is associated with organic storage. Emits.

Subsequently, after passing through the anaerobic tank, the wastewater is supplied to an anoxic tank, which is the next step. In the anoxic tank, nitrous acid and nitric acid are converted into nitrogen gas and removed by denitrifying microorganisms. Then, the waste water is introduced into the aeration tank after the anoxic tank, and the organic matter contained therein is decomposed into carbon dioxide and water by the microorganism in the aeration tank, and ammonia nitrogen is nitrified to nitrous acid or nitric acid by the nitrifying microorganism.

In addition, the accumulating bacteria are excessively ingested with phosphorus as oxidative decomposition of accumulated organic matter proceeds, and the phosphorus is removed in the form of sludge. At this time, the aeration pipe is continuously disposed in the aeration tank by the blower in the bottom, and the injected air maintains the oxygen concentration in the aeration tank.

Then, the wastewater treated in the aeration tank is introduced into a separate sedimentation tank through a discharge pipe and discharged to the outside so as to reuse only the treated water in which the sludge has settled, and the sludge precipitated in the sedimentation tank is carried out by the sludge transport pump. The sludge, which is recycled into the tank and settled in the aeration tank, is recycled by an internal circulation pump.

However, even by such a prior art, decomposition of hardly decomposable organic substances such as chlorine-based aliphatic carbohydrates (CAHs) is not performed properly, and even when used as heavy water, there is a problem that does not meet the residual chlorine standard. In addition, the water used as heavy water did not provide any solution for recycling, which caused problems due to the exhaustion of water resources.

Accordingly, the present invention is to solve the above problems, by repeatedly or selectively creating an anaerobic and aerobic environment from the incoming sewage and wastewater and sewage to induce decomposition of organic matter, nitrification reaction and phosphorus release as well as biofilm media The purpose of the present invention is to provide an advanced treatment system for wastewater and sewage, which is advantageous in terms of water resource management through recycling and reuse of treated water by removing hardly decomposable organic matter.

The advanced wastewater treatment system for wastewater and sewage of the present invention is treated with anaerobic tank 100 into which anaerobic wastewater or sewage is first introduced, and the anaerobic tank 100 is treated from the anaerobic tank 100 as shown in FIG. 1. Water flows into the anaerobic tank 100 and the anaerobic tank 200 for creating an anaerobic environment, the phosphorus removal tank 300 for removing phosphorus contained in the sludge, and in communication with the anoxic tank 200 repeatedly or selectively And an aeration tank 400 for circulating with the anoxic tank 200 to create an aerobic environment and a biofilm treatment tank 500 in communication with the aeration tank 400 and configured with a detachable biofilm, and further comprising the biofilm treatment. And use means 600 for communicating with the tank 500 and using the treated water purified from the biofilm treatment tank 500 as heavy water.

 In other words, the present invention is a pretreatment for inflowing wastewater and sewage so that the incoming waste, wastewater and sewage are denitrified by nitrogen gas with nitrate nitrogen in the anaerobic tank 100 and the anaerobic tank 200. The wastewater and sewage pretreated in the anaerobic tank 100 and the anaerobic tank 200 decompose the organic matter under an aerobic environment in the aeration tank 400, and at the same time, the biodegradable organic matter through the filtration chamber 430. The primary decomposition is to purify the water to be suitable as heavy water. In addition, the treated water finally treated in the aeration tank 400 is introduced into the biofilm treatment tank 500 and treated to decompose organic matter secondary by the biofilm 510. The present invention relates to a system for helping to recycle wastewater and sewage as heavy water by using the same as the use means 300 including).

Here, the term "biofilm media" defines a member that enables biological treatment of wastewater, wastewater and sewage. The biofilm 510 and the filtration chamber 433 of the filtration chamber 430 of the biofilm treatment tank 500 Corresponds to the biofilm media. In addition, the term "sewage, wastewater and sewage" is a broad concept including wastewater, such as rainwater, domestic wastewater and building sewage, as well as factories, barns, pigs. Such wastewater, wastewater and sewage contain various organic matters and solids, and especially when hardly decomposable organic matters are contained, it is not easy to process them. In the present invention, the biodegradable organic matters are decomposed as heavy water by using biofilm media. It is to provide treatment water that meets the water quality standards.

In addition, the use means 600 may be operated by the independent power management unit 800 optionally by using the solar power, or the like instead of the main power by the independent power management unit 800 to operate the system without considering local conditions, and energy To save.

Hereinafter, the components of the present invention will be described with reference to FIGS. 2 to 7.

The anaerobic tank 100 and the anaerobic tank 200 is a bar for forming an anaerobic condition, the stirring means is configured, for example, as shown in Figure 2 can be presented a water pump, preferably shown in the drawings Although not yet, it is to be provided with a stirring / liquid transfer device configured to be capable of liquid transfer at the same time with its own agitation, in the anoxic tank 200 so that the stirring / liquid transfer device is stirred at the same time as the liquid transfer from the anaerobic tank (100) It is reasonable to promote the denitrification reaction.

In addition, although not shown in the drawings, the circulation means may be configured between the tanks so that circulation of mixed liquor suspended solids (MLSS) may be formed between the anaerobic tank 100 and the anaerobic tank 200. As the inflow (liquid transfer) means, the above-described stirring / liquid transfer apparatus may perform the function, and in addition, a conveying means for conveying the liquid between the groups may be further configured.

Due to the action of the stirring / liquid transfer device, the liquid is transferred from the anaerobic tank 100 to the anoxic tank 200 and at the same time, the aerobic tank 200 has a stirring action for smooth sludge agitation. This will increase the chance of contact between organics and microorganisms.

On the other hand, the interaction of the anaerobic tank 100 and the anaerobic tank 200 described above,

First, the wastewater and sewage are continuously or intermittently introduced into the anaerobic tank 100. The wastewater and sewage received in the anaerobic tank 100 in which the anaerobic environment is maintained reacts to induce organic matter with induction of phosphorus release. Will be removed.

Then, the reaction solution of the anaerobic tank 100 may be stirred in the oxygen-free tank 200 at the same time as the liquid transfer or liquid transfer to the oxygen-free tank 200 by a pump or the above-described stirring / liquid transfer device. In this case, of course, only stirring action without liquid transfer is possible. As a result, in the anaerobic tank 200, the organic matter contained in the wastewater and the sewage is introduced into the anaerobic tank 100 in a stepwise or continuous manner to denitrate the nitrate nitrogen in the wastewater and the sewage (NO3). → N2).

In addition, as described above, optionally, the treated water of the anoxic tank 200 may be conveyed to the anaerobic tank 100 by a conveying means (not shown), and the anaerobic tank 100 may be removed from the anaerobic tank 200. The organic material returned is to make phosphorus release through the absorption of VFAs of the phosphorus-removing microorganism more active.

On the other hand, the aeration tank 400 is in communication with the anoxic tank 200 is introduced into the treated water in which the denitrification reaction, etc. in the anoxic tank 200, as shown in Figure 3 the inner partition walls (471, 472, 473) By the anaerobic tank 100, an anaerobic tank 200 and the biofilm treatment tank 500, and the like, respectively, the aeration tank 400 is configured with an acid pipe 421 in the lower portion of the biofilm treatment tank 500 and compartments The filtration chamber 430 is configured on the inner partition wall 473.

In addition, the aeration tank 400 is formed by an aerobic environment by the aeration of the acid pipe 421 configured in the lower portion is to decompose the organic matter, the nitrification reaction (NH3 → NO3) is to proceed.

In addition, although not shown in the drawings, the aeration tank 400 and the oxygen-free tank 200, as well as the anaerobic tank 100 and the oxygen-free tank 200, as well as a water pump or a stirring / liquid transfer device is provided with a conveying means and the liquid circulation With this, the circulation of MLSS is made. Accordingly, the phosphorus released by the anaerobic reaction by the anaerobic tank 100 and the anoxic tank 200 causes phosphorus absorption by the phosphorus removing microorganism, and the phosphorus thus absorbed through the phosphorus removing tank 300 described below. Removed.

On the other hand, the water in which the organic matter is decomposed in the aeration tank 400 passes through the filtration chamber 430, the filtration chamber 430 is the rear surface of the inner compartment wall 273 (surface in contact with the biofilm treatment tank 500) To be configured to, the inlet 431 is configured at the bottom to allow the water passed through the aeration tank 400 to be introduced through the inlet 431. The inlet 431 is formed in the inner partition wall 273 as shown in FIG. For this configuration, the inner partition wall 273 is formed to completely block the aeration tank 400 and the biofilm treatment tank 500 so that water passing through the aeration tank 400 is introduced into the inlet 431. do. Water flowing into the inlet 431 flows upwardly from the downward direction of the filtration chamber 430 to pass through the carrier 433 so that organic matter, solids, etc. are filtered out by adsorption, filtration, and the like. Organics are filtered out.

Thus, the water passing through the carrier 433 is to flow to the biofilm treatment tank 500 through the outlet 432 configured on the filtration chamber 430. The carrier 433 is configured to partition the top, bottom in the center of the filtration chamber 430, which will be described in more detail in the filtration chamber 430, the carrier frame 434 to partition the top, bottom in the center It is suitable that the carrier frame 434 is filled with a scoria 433-1 with the carrier 433. Such a s Korea is a porous material that is easy to adsorb and is given conditions that are easy to grow microorganisms based on porosity.

The Korea 433-1 is a kind of volcanic products. In Jeju Island, there are many Koreans called volcanic eruptions, also called Song. Jeju Island on Jeju Island is a volcanic rock material that contains volcanic rock, volcanic sand and other volcanic ashes. About 75% of the components of SK Korea are silicon oxide (SiO₂), aluminum oxide (Al₂O₃) and iron oxide (Fe₂O₃). In addition, calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (K ₂O) and sodium oxide (Na₂O) and nickel oxide (TiO₂). The shape of the sea Korea is porous and its specific surface area is about 100m₂ / g, which is relatively large, providing a good environment for microorganisms to grow. In addition, S Korea has physical and chemical and biological stability, high mechanical strength and durability, there is an economic advantage that can be used to collect natural materials. In other words, by using the SKO (433-1) as a carrier, it is possible to filter by the adsorption of organic matter, and the biological environment of the microorganism can be formed by the porous material of the SKO (433-1). .

In addition, the S Korea 433-1 is characterized by suppressing the increase in pH in the appropriate line as the pH is about 6 to 7. In other words, excessive pH increase during the purification of water may cause deactivation of microorganisms, which may lower the purification efficiency and should satisfy the pH standard even when discharged as heavy water. pH rise can be suppressed by a titration line.

In addition, the present invention provides an example in which the carrier ball 433-2 is further used as the carrier 433 as the carrier 433 as shown in FIG. 4.

Here, the carrier ball 433-2 is characterized in that it has a ball shape by mixing 20 to 30 parts by weight of steelmaking slag, 5 to 10 parts by weight of water, 0.1 to 0.5 parts by weight of soil hardener. That is, the support ball 433-2 is manufactured in a spherical shape to form a constant particle by mixing the peat, steelmaking slag, water, soil hardener through a firing step.

The steelmaking slag can be divided into converter slag and electric furnace slag. The converter slag is a slag produced when melting raw steel, and is different from the electric furnace slag produced when melting scrap iron. Direct reduction of CAHs or reduction of hydrogen ions through oxidation can be expected. Steel slag is essentially lighter than iron and is separated by the difference in specific gravity, so it contains little heavy metal and thus has low environmental hazard.

The peat is a peat, such as moss, reeds, sedges and plants, or woody fluids, such as pine and birch, are thickly deposited in the basin, and are decomposed and altered by biochemical changes such as fungi in the presence of water. Peat is broadly included in one type of coal, but is generally distinct from coal. Unlike peat, which is buried underground like coal, which has been fished under acupressure and geothermal action for many years, the main components of the plant are lignin and cellulose, which are mainly formed by decomposition in the surface. In the present invention, peat includes all kinds of peat, but not limited to tundratan, peat, wood peat and the like.

The carrier ball 433-2 is made of steel slag and peat as a main component to reduce dechlorination by reducing chlorine-based aliphatic carbohydrates (CAHs) as a hardly decomposable substance. That is, as a pretreatment, organic matters are decomposed under an aerobic environment in the aeration tank 400, and organic matters are decomposed by adsorption and the like by another s Korea 433-1 as another carrier, but in this case, chlorine-based aliphatic carbohydrates ( CAHs may be discharged together with the treated water as it is, as shown in Figure 4 by mixing the carrier 433-1 and the carrier ball 433-2 with the carrier 433 in the filtration chamber 430 It is intended to remove degradable and hardly degradable organic matter.

In particular, the support ball 433-2 is provided in the form of a ball by firing by appropriately mixing water and soil hardener in the steelmaking slag and peat, the porosity due to the microorganism propagation due to the reaction of the long time (433-1) By preventing this from falling, the flow of the fluid in the filtration chamber 430 is prevented from being lowered, thereby controlling the wall effect. That is, by forming the proper pores in the carrier 433 by the ball carrier ball 433-2, the organic matter removal efficiency is reduced or the blockage is prevented.

Thus, the support ball 433-2 is a mixture ratio of the steelmaking slag and the peat to provide a proper mixing ratio in producing a ball form, the mixing ratio is limited to 20 to 30 parts by weight of steelmaking slag 100 parts of peat It is reasonable. If the blending ratio of steelmaking slag exceeds 30 parts by weight, the pH will be 7.5 or more, and the alkalinity will not provide an environment suitable for the growth of microorganisms, and if it is less than 20 parts by weight, the removal rate of chlorine-based aliphatic carbohydrates will be reduced. .

Meanwhile, in the present invention, as shown in FIG. 4, a plurality of diffuser devices 480 may be configured on the bottom surface of the aeration tank 400.

The diffuser device 480 includes a rotating plate 482 configured to be rotatable at an inner circumference of a hollow support 481 and an upper end of the support 481, and a spring 483 attached to an upper surface of the rotating plate 482. It is attached to the spring 483 and formed integrally with the support protrusion 484-1 and the support protrusion 484-1 located at the inner circumference of the support 481, the spiral groove 484- 2) is composed of a rotating hole 484 to form a head 484-4 having a larger diameter.

The support 481 is configured on the lower surface of the aeration tank 400 to form a hollow so that the rotating plate 482 is configured to be rotated on the inner circumference, and the spring 483 is applied to the upper surface of the rotating plate 482 Furnace rotator 484 is to be fastened to enable vibration and rotation.

The diffuser 480 according to this configuration should be configured such that the head 484-4 is positioned above the diffuser 421, whereby air injected from the diffuser 421 is injected into the head 484. By striking -4), vibration energy and rotational energy are added to the water in the aeration tank 400 by the structure of the spring 483 and the spiral groove 484-2. That is, the air (oxygen) aerated by the addition of this energy is increased in the dissolved rate in the water stored in the aeration tank 400, this high dissolution rate is to activate the aerobic microorganisms to increase the decomposition efficiency of the organic matter.

As such, by further configuring the diffuser 480 separately from the diffuser 421, the dissolution rate can be physically increased without increasing the amount of electricity used, thereby enabling an environmentally friendly operation in terms of energy. In addition, the vibration energy added by the air diffuser 480 may deactivate bacteria and the like, so that the effect of sterilization may be obtained at the same time.

By this configuration, the installation height is adjusted up and down by sliding the biofilm frame 530 in the guide rail 540, it is easy to detach when necessary. The configuration for sliding the biofilm frame 530 up and down is not shown in the drawings, but can be slid on the guide rail 140 by pulling and releasing the string by hanging a string on the biofilm frame 530. Will be. Wastewater and sewage by the biofilm treatment tank 500 is to decompose organic matter secondary.

On the other hand, the advanced treatment system of sewage, wastewater and sewage according to the present invention includes a phosphorus removal tank 300 for removing phosphorus absorbed by the phosphorus removal microorganisms in the aeration tank 400 described above.

That is, the phosphorus contained in the sludge form in the aeration tank 400 is finally transferred to the biofilm treatment tank 500 according to the transfer process of wastewater, the sludge is transferred to the biofilm treatment tank 500 The phosphorus removal tank 300 is conveyed together with the water by a conveying means including an underwater pump provided to recover and remove phosphorus contained in the sludge.

Here, the phosphorus recovery and removal process of the phosphorus removal tank 300 is to solidify phosphorus using a flocculant, and then to separate and recover the flocculant and phosphorus from the solid material using an eluting material, or to recover the phosphorus using an adsorbent After the adsorption, the specific description that can be carried out through a known technique including a physicochemical process of desorbing and recovering phosphorus through a phosphorus desorption material will be omitted.

Meanwhile, the treated water purified by the above-described configurations may be used for various means of use 600 as heavy water. In FIG. 6, an artificial pond 610 is shown.

The artificial pond 610 is formed with an artificial tank 611 to form an artificial pond by forming a space therein so that the treated water is stored. The artificial tank 611 is not limited to its shape and may be selectively considered according to the place where it is installed.

The inflow of the treated water from the biofilm treatment tank 500 through the inlet pipe 612 is not shown in the figure, but is enabled by the action of the pump. The inlet pipe 612 is installed higher than the height of the artificial water tank 611 is configured to communicate with the artificial waterfall 613. The artificial waterfall 613 has a storage space 613-1 communicating with the inflow pipe 612 at an upper portion thereof, and falling down so that the treated water flowing over the storage space 613-1 can fall. -2) is configured to be exposed to the outside. That is, the treated water flowing into the inflow pipe 612 is stored in the storage space 613-1, and the treated water flowing out of the storage space 613-1 falls freely to the falling surface 613-2, thereby causing artificial waterfall.

In other words, the auxiliary power unit 820 builds a hybrid hybrid power generation including a wind generator that generates power by wind and a solar generator that generates power by solar, and from the wind generator and the solar generator The generated power can be used as an auxiliary power source or an alternative power supply for a load such as a pump, a blower, and the like.

In this way, the power generated from the auxiliary power supply unit 820 is stored in the exhaust processor 830. The battery unit 830 is connected to the charge / discharge controller 840, and the power of the auxiliary power stored in the battery unit 830 is charged and discharged in real time under the control of the charge / discharge controller 840. Here, the charge / discharge controller 840 compensates for mutual disadvantages from clean energy such as wind power generation or solar power generation and supplies power to a load required by storing energy in the battery unit 830. For example, wind power can be generated 24 hours, but the output fluctuates severely, and wind speed tends to be low in summer and high in winter. On the other hand, solar power can only be generated during the daytime when the sun is present, and solar radiation tends to be higher in summer and lower in winter than wind.

As described above, power generated by mutually generating power depending on sunset, sunrise, or season is stored in the battery unit 830 through the charge / discharge controller 840 collectively.

In addition to the charge and discharge controller 840 may include a power processing unit 850, overcharge protection unit 860 and reverse voltage protection unit 870. The power processing unit 850 processes the power stored in the battery unit 830 from the auxiliary power supply unit 820 so as to correspond to the use voltage of the load.

That is, the power processing unit 850 outputs the power stored in the battery unit 830 to a power suitable for the voltage used for the load, and for this purpose, a converter such as an inverter or a converter may be included. The overcharge preventing unit 860 extends the life of the battery unit 830 by preventing overcharging of power stored in the battery unit 830 from the auxiliary power supply unit 820.

In addition, the reverse voltage prevention unit 820 blocks the reverse voltage of the power generated by the auxiliary power supply unit 820 to load the load of the battery unit 830 connected to the charge / discharge controller 840 and the pump, blower, and the like. Protect.

The controller 850 is connected to the charge / discharge controller 840 and the main power unit 810, and performs real-time monitoring on the main power supplied to the load, such as a pump and a blower, and grasps the disconnection state of the main power. By controlling the supply amount of the auxiliary power and the main power delivered from the charge / discharge controller 840, the auxiliary power is to be supplied to the main power or to the load in general.

Hereinafter, with reference to Figure 2 will be described the operating state based on the flow of water in the wastewater and sewage advanced treatment system of the present invention.

The advanced wastewater treatment system for wastewater and sewage of the present invention is first introduced into the anaerobic tank with the wastewater and sewage. The wastewater, sewage and sewage introduced into the anaerobic tank 100 are treated to denitrate nitrogen nitrate with nitrogen gas together with phosphorus release by anaerobic conditions in the course of being transported (w1) or circulated to the anaerobic tank 200.

Thereafter, the treated water w2 treated in the anoxic tank 200 is transferred to the aeration tank 400 to remove organic matter primarily by physical and biological treatment in the aeration tank 400.

Specifically, the aeration tank 400 has an diffuser 421 formed at the lower portion thereof to increase the amount of dissolved oxygen (DO) inside the aeration tank 400. In addition, aerobic microorganisms are activated, and organic matter present in the wastewater and sewage (w2) introduced by the aerobic microorganisms is primarily decomposed. In this case, the blower b1 supplies oxygen a1 to the diffuser 421. Based on this action, the aeration tank 400 decomposes organic matter by aerobic microorganisms and induces nitrification.

In addition, in the aeration tank 400, phosphorus released by the treatment of the anaerobic tank 100 and the anaerobic tank 200 is carried out by phosphorus removal microorganisms.

Thereafter, the wastewater and sewage (w3) in which nitrification and phosphorus absorption and organic matters are removed from the aeration tank 400 are introduced into the filtration chamber 430. The carrier 433 is embedded in the filtration chamber 430 and adsorbed therein. , Filtration is performed. The carrier 433 includes a s Korea / carrier ball to remove particularly decomposable organic matter from wastewater and sewage. The treated water (w4) in which the biodegradation and particle filtration is performed through the filtration chamber 430 is transferred to the biofilm treatment tank 500 to undergo a secondary organic decomposition process, and to the use means 600 depending on the purpose. Inflow. That is, for example, the feed pump (P1) is introduced into the artificial pond 610 into the inflow water (w5), in some cases circulated back to the biofilm treatment tank 500 as circulating water (w8). In addition, the sprinkler 620 is introduced into the inflow water (w6) is sprayed on the grass and used.

On the other hand, the biofilm treatment tank 500 is introduced into the treated water (w4) from the filtration chamber 430 of the aeration tank 400. The biofilm treatment tank 500 has a biofilm 510 embedded therein, and a diffuser 520 is formed at the lower portion thereof to activate the aerobic microorganisms present in the biofilm 510, and the treated water introduced by the aerobic microorganisms ( The organic matter present in w4) is secondaryly decomposed.

The diffuser 520 also corresponds to a configuration in which dissolved oxygen (DO) is increased by aeration of the oxygen (a2) supplied by the blower (b2) into the biofilm treatment tank (500).

On the other hand, the treated water (w7) contained in the biofilm treatment tank 500 is to be returned to the phosphorus removal tank (300). The sludge contained in the treated water w7 includes phosphorus absorbed by the action of the aeration tank 400, and the phosphorus removal unit 300 recovers phosphorus through a physicochemical method.

Meanwhile, although not shown in FIG. 2, the submersible pump, the transfer pump p1, and the blowers b1 and b2 are supplied with power by the independent power management unit 800, so that solar power and wind power are supplied without or without electricity. By making it available, the system can also be operated in island areas.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
