Description

Fixed bed carrier for waste water purification and sewage treatment apparatus using the same

The present invention relates to a stationary bed carrier for wastewater purification that can be manufactured at low cost, and an eco-friendly stationary bed carrier for wastewater purification that can be used semi-permanently by being buried underground in a small size and a sewage treatment apparatus using the same.

BACKGROUND ART As a method for purifying wastewater such as various wastewater or domestic sewage, a biological treatment method which is conventionally treated with microorganisms is known. In the early stages of biological treatment methods, activated sludge or long-term aeration methods using suspended growth microorganisms were used a lot. However, due to various problems such as large sludge, it is difficult to cope with large loads of influent and large amounts of excess sludge are produced. Many biocontact methods have been used to treat waste water while maintaining high concentrations of microorganisms attached to a carrier. In the biocontact process using the carrier, the microorganisms adhere to the carrier to form a biofilm, so the physiological mechanism is different from that of the microorganism in the suspended state, resulting in an increase in growth rate, an increase in metabolic activity, and resistance to toxic substances. Processing efficiency is improved and stable operation management is easy.

The carrier should have a wide specific surface area and excellent porosity since microorganisms should adhere to the surface to form a microbial membrane well. Carriers currently used in general, such as crushed stone, fiber yarns, fluidized porous plastics, activated carbon, particulate ceramics, natural wood carriers, etc. have been commercialized and used.

When the carrier is classified according to physical properties, the carrier may be classified into a fixed bed carrier that is highly concentrated in water and a fluid bed carrier that is light and floats on the water surface. Fluidized bed carriers have excellent porosity and have a large specific surface area, which can maintain a high concentration of microorganisms per unit volume. On the other hand, they are suspended in water and collide with each other due to their low specific gravity. There are drawbacks to be constantly replenishing. The stationary phase carrier is fixed in water to facilitate the formation of microbial membranes and can be used semi-permanently.However, due to the lack of pores for activation of high concentrations of microorganisms and the small specific surface area, the contact area for microorganisms to remove contaminants can be reduced. There is a disadvantage of low efficiency.

Therefore, in recent years, many methods for producing a fluidized bed carrier rich in pores and a large specific surface area as a fixed bed have been tried. In case of fluidized foamed resin, it is used as fixed bed by making square frame or round frame that can hold carrier, but it is impossible to fill enough amount to increase sewage treatment efficiency by large volume of frame. It becomes the factor of. In the case of the bio-fixed bed carrier using fiber yarns, sufficient microorganisms can be fixed and sedimentation after sewage treatment can be easily performed, but installation is limited because it must be fixed in a special apparatus, and the installation method is not only complicated, There are problems such as the need to replace periodically.

On the other hand, in recent years, as the national income level is improved and the quality of life is increased, the demand for rural housing that can enjoy the fresh air and good scenery is increasing rapidly.

As a result, small-scale housing complex projects such as Dong-ho-in complex are located near valleys and streams near the city center, and environmental pollution is intensified due to reckless exploitation of valleys, and water pollution on clear streams is becoming serious.

The reckless development of rural housing complexes is raising interest in the construction of eco-friendly and eco-friendly houses. In particular, as complaints from local residents gradually increased as water pollution caused by oh and drainage deepened, local governments showed great interest in the treatment equipment to purify oh and drainage by complexes. In order to solve this problem, we welcome the installation of purification facilities in the complex, so it is necessary to develop a wastewater treatment system that is environmentally friendly and requires little management.

The government has also encouraged eco-friendly housing management by minimizing environmental degradation and preventing indiscriminate discharge of wastewater and drainage through green architecture certification or environmental certification system, but until now, there are no appropriate regulatory measures. It is due.

However, at present, there is no environment-friendly wastewater treatment device for home use, and there is a problem in that it is difficult to apply the wastewater treatment device used in factories or local governments for home use in terms of cost or post-installation operation.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like elements throughout the specification.

In this specification, terms such as "comprise" or "have" are intended to indicate that there is a feature, number, step, action, component, part, or combination thereof described on the specification, and one or more other features. It is to be understood that the present invention does not exclude the possibility of the presence or the addition of numbers, steps, operations, components, parts, or combinations thereof. In addition, when a part such as a layer, film, region, plate, etc. is said to be "on" another part, this includes not only when the other part is "right on" but also another part in the middle. Conversely, when a part such as a layer, film, region, plate, etc. is "below" another part, this includes not only the other part "below" but also another part in the middle.

In the technology of purifying sewage, the pore-rich carriers provide the best environment for microorganisms to inhabit coliform bacteria and BOD by filamentous fungi and protozoa. In addition, the grass on the ground can extend the roots to reduce nitrogen and phosphorus removal ability by more than 20%, and the soil contact surface can supply soil microorganisms to the treatment device to remove BOD and other harmful substances that may be introduced. .

The wastewater purification carrier 1 according to the present invention, as shown in FIGS. 1 to 4, includes a carrier body 10 and a weight body 20.

The carrier body 10 is made of porous plastic foam is foamed so that microorganisms can inhabit.

At this time, the carrier body 10 is made of a hexahedron, and the hole 11 is formed as a through hole. Of course, the carrier body 10 may be a synthetic resin foam of various three-dimensional shape in addition to the hexahedron.

In this case, the carrier body 10 may be foamed polyurethane, foamed polyvinyl alcohol, or the like. These synthetic resins can be used once they are foamed one or more times to create the appropriate voids. In addition, since the synthetic resin foam is excellent in elasticity, there is no difficulty in binding the weight body 20 by interference fit.

The weight body 20 is inserted into the through-hole 11 formed by cutting a part of the carrier body 10 by interference fit.

In this case, an enlarged diameter portion 11a having an enlarged diameter may be formed at the center of the through hole 11 to allow the weight body 20 to be seated. It is of course also possible for the through holes 1 to simply have the same diameter.

It is preferable that the weight 20 uses a stone which is almost inexpensive. Of course, it is also possible to use a weight made of a different material depending on the nature, such as the addition of functionality.

Referring to FIG. 1, the carrier 1 may be formed of a carrier body 10 having a cube shape, and a stone 20 that is a weight body inserted into the through hole 11 of the carrier body 10.

Referring to FIG. 2, the weight body 10 is inserted into the center of the through-hole 11 of the carrier body 10 by interference fit and shows a fixed state. Therefore, when supplied to the aeration tank in such a state, even if the aeration proceeds, the state constantly sinks to the bottom of the aeration tank at all times, so that microorganisms can easily inhabit.

Referring to FIG. 3, the weight body 20 is fixed to the center of the carrier body 10.

Referring to FIG. 4, it can be seen that the through-hole 11 is formed in the center of the carrier body 10. Since the carrier body 10 is a synthetic resin foam, it is elastic and inserts a stone, which is a weight body 20 which is slightly larger in diameter than the through hole 11, by inserting a stone.

On the other hand, the natural purification sewage treatment apparatus to be developed in the present invention as shown in the drawing as a high-treatment apparatus that can remove the pollutants in the waste water by using the purification action of soil microorganisms and plants to discharge the clear treated water.

Pollutants that are most problematic in domestic wastewater and drainage can be regarded as organic substances that can be a growth source for nutrients and toxic microorganisms such as nitrogen and phosphorus. The basic process of this sewage treatment system is currently used in village sewage treatment. Bio-contact oxidation method using a carrier is applied to A ₂ O process which is most used for material removal.

The A ₂ O process is composed of anaerobic tank, anaerobic tank, aerobic tank, the size was 1: 1: 3 in consideration of the pollutant treatment efficiency of the microorganisms living in each tank. In anaerobic tanks, phosphorus is released from the microorganisms when organic matter is ingested by the phosphorus-removing microorganisms. More than half of the organic matter is removed during the anaerobic and anaerobic tanks. In addition, by placing an anaerobic tank behind the anaerobic tank, it is possible to prevent the phosphate release of phosphorus-removing microorganisms due to nitrate nitrogen from the return.

In the anoxic tank, the nitrogen nitrate returned from the settling tank by the denitrification microorganism is converted to N ₂ (gas) using an electron acceptor to remove nitrogen (denitrification). Organics are used as an energy source for denitrification, which can lead to effective organic matter removal. In the subsequent aeration tank, the remaining organics are removed by aerobic microorganisms, with all the microorganisms being precipitated out in the sedimentation tank together with the phosphorus-removing microorganisms that overdose phosphorus. Also, by installing the second and third aeration tanks, it is possible to maintain higher nitrification.

The aeration tank is filled with a carrier (1) to prevent desorption of microorganisms and to maintain environmental conditions resistant to environmental factors. In the biofilm process using the carrier (1), the microorganisms are attached to the carrier (1) to form a biofilm, which increases the growth rate, increases metabolic activity, and resistance to toxic effects compared to the microorganisms in a dispersed state. It is strong. In the aeration tanks 1 and 2, a carrier rich in pores (1) is used, and tank 3 is filled with other carriers such as oyster shells which are effective for removing phosphorus.

The upper part of the treatment tank is covered with high-quality soil, and the grass is planted. The coated soil continuously improves treatment efficiency and stabilizes treatment by continuously supplying soil microorganisms and soil animals, which are particularly effective in removing nutrients. have. Grasses planted in the topsoil will be lowered to the lower layer of the septic tank and grow between the carriers, improving the removal efficiency of nutrients such as nitrogen and phosphorus by 20% or more.

The grass planted on the topsoil forms a beautiful green space, which can be combined with the surrounding landscape and can be used as a resting place for residents.

To date, no sewage treatment system (10㎥ / day or less) specialized in small rural housing complexes has been commercialized, and we will compare it with a relatively large village sewage treatment system (50㎥ / day or more) to discuss the technical difference.

The village sewage treatment facility replaces the existing sewage treatment plant or a sewage treatment plant of a certain size, and is mainly installed in urban areas, rural areas, and mountainous areas where sewer pipes are difficult to install. As the applied method, the contact oxidation method is about 45%, the activated sludge method is about 25%, the soil trench method is 16%, the anaerobic aerobic method is about 10%, and other methods are about 4%.

Biocontact oxidation method using a carrier is a basic method to be used in the sewage treatment apparatus of the present invention can prevent the desorption of microorganisms to maintain a high concentration of microbial communities in the treatment tank to maximize the treatment efficiency in a small space. In addition, since the microorganisms are attached to the carrier to form a biofilm, the resistance to the influx of toxic substances is increased, and thus it is very resistant to rapid environmental changes, which is the most preferred method for small and medium-sized sewage treatment apparatus.

Differences between the natural purification sewage treatment apparatus and the existing biological contact apparatus to be developed in the present invention are as follows.

The soil layer is coated on the upper part of the treatment tank to continuously supply soil microorganisms to the treatment tank to increase treatment efficiency and stabilize the treatment. Existing bio-contact devices mainly use wastewater microorganisms, but soil microorganisms have the advantages of faster growth rate and resistance to toxic substances than wastewater microorganisms, and removal of odors, pathogens and pests by soil coating. Excellent efficiency at

In addition, it is an advanced treatment device that can remove the pollutants in the sewage efficiently by using the evaporation of the plant and the purification of the roots to discharge the clear treated water.

The grass planted on the topsoil forms a green space and can be combined with the surrounding landscape of the country house and can be used as a resting place for residents.

Existing large-capacity sewage treatment devices are not easy to manage and have high treatment efficiency due to complex mechanical devices. However, the sewage treatment apparatus according to the present invention is a device specialized for small-scale residential complexes, and requires little management, and has a high treatment efficiency, and is an advanced treatment apparatus capable of discharging clear treatment water in a short residence time. Possible packaged processing units.

Hereinafter, with reference to the drawings will be described in more detail the natural purification sewage treatment apparatus according to an embodiment of the present invention.

5 to 9, the anaerobic tank 110, the anaerobic tank 120, the

aeration tank

In the anaerobic tank 120, sewage is introduced from the anaerobic tank 110, denitrification is performed, and organic matter is removed.

The

aeration tanks

130, 140, and 150 are introduced with sewage through the anaerobic tank 120, provided with aerobic microorganisms for removing organic matter, and filled with a carrier so that the aerobic microorganisms are attached to form a biofilm. In addition, the lower end of the air supply pipes (131, 141, 151) for aeration is installed is connected to the air pump.

At this time, if it is assumed that the volume constituting one tank is almost the same, the number of anaerobic tank 110, anoxic tank 120, and aeration tank (13-150) is set to 1: 1: 3.

The sedimentation tank 160 is the sewage from the aeration tank (130,150) and then all the microorganisms are settled, the purified water is discharged through the outlet (102).

Here, the movement of the sewage between the tanks (110-160) can be applied to all methods, such as using the siphon 105 or overflow.

It is desirable to install for this purpose.

Basically, the carrier 1 can be applied to the carrier 1 according to the embodiment of the present invention described above. That is, the carrier 1 in which the weight 20 is inserted into the synthetic resin foam can be used.

In this case, the carrier may be applied to one or more of crushed stone, particulate ceramics, wood chips, expanded polyurethane, expanded polyvinyl alcohol, suspended microbial film, oyster shell.

On the other hand, for example, the first two aeration tanks (130, 140) of the three aeration tanks (130-150), aeration-rich crushed stone carriers are used in the aeration tank 150, the last aeration tank 150 is effective for removing phosphorus The shell can be filled. Of course, in addition to the crushed stone or oyster shell can be applied to the fixed-phase foamed resin carrier rich in voids. Stationary phase carriers provide the best environment for microorganisms to eliminate E. coli and BOD by filamentous fungi and protozoa. In addition, the grass on the ground can extend the roots to reduce nitrogen and phosphorus removal ability by more than 20%, and the soil contact surface can supply soil microorganisms to the treatment device to remove BOD and other harmful substances that may be introduced. .

In addition, the plant layer 260 may be planted by selecting one or more kinds of four seasons grass, buttercups, leek, pussy willows, boulders, reeds, ropes, moon root grass, silver grass. The present invention will be applied to a house or for each housing complex, so it will be a lot of plants to plant the most preferable aesthetics.
