Conventional sewage treatment facilities mainly use the standard activated sludge process or an additional or modified method of the above method, and use A2 / O process, UCT process, VIP process, etc. in foreign countries, and the above- The A / O process is a biological treatment process for removing nitrogen and phosphorus by improving the A / O process. The reaction tank is an anaerobic tank, an anoxic tank, (Anoxic Tank) and Aerobic Tank. It consists of Nitrifer Recycle to remove nitrate nitrogen and settler sludge return. In anaerobic tank, it releases phosphorus in anaerobic condition, And the anoxic tank removes nitrogen and phosphorus by denitrifying nitrate in the aerobic tank's internal return water.

The A ₂ / O process removes nitrogen and phosphorus from the sewage to reduce nutrients in the sewage but focuses only on the removal of nitrogen and phosphorus in the sewage. In recent years, harmful bacteria and microorganisms There is a problem that it can not be removed.

The sewage treatment plant is operated as a biological treatment method using a method in which the pollutants are decomposed by microorganisms.

Especially, in carrying out sludge treatment through anaerobic digestion tank, A pretreatment process for solubilization is carried out in order to increase the water content of the microorganisms. Examples of the pretreatment techniques include a biological method using high temperature aerobic microorganisms, a physical method using ultrasonic waves and hydrodynamic cavitation and thermal hydrolysis and ball milling apparatus, A chemical treatment method, a complex treatment method in which a plurality of the treatment methods are combined, and an electrical method using electrolysis are used, but they are expensive and have a problem in that they are difficult to be put to practical use due to their low cost.

Korean Patent No. 10-135458 discloses a sludge solubilization method for increasing the digestion efficiency of the anaerobic digestion tank, wherein the excess sludge generated in the wastewater treatment process is treated with an alkali catalyst and methanol to soften or destroy the cell membrane of biodegradable microorganisms in the sludge The difficulty of the operation management and the management cost of the anaerobic digestion efficiency by the anaerobic microorganism of the digester are problematic.

Hereinafter, preferred embodiments of the present invention will be described. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art.

An SBR reaction tank for sewage treatment and an energy production type sewage treatment system of the present invention will be described with reference to the drawings.

FIG. 1 schematically shows the structure of an SBR reaction tank according to an embodiment of the present invention, and includes a treatment tank 100 and a hybrid strain isolator 200. The treatment tank 100 is a place where the ammonium-containing desolvation solution generated in the digester is introduced and resides, and is reacted with anaerobic ammonium-oxidizing bacteria (Anammox) to lower the ammonium content of the ammonium-containing desorption solution.

After the reaction has been completed, the effluent will contain a mixture of granules and activated sludge produced by anaerobic ammonium-oxidizing bacteria (Anammox). At this time, the hybrid strain separator 200 is used in the present invention in order to separate and use the particle size difference between the granules and the activated sludge.

The hybrid strain isolator 200 will be described in more detail with reference to FIG.

The hybrid strain isolator 200 includes a housing; A hybrid strain isolator 210 located inside the housing and having a truncated cone shape; An injecting unit connecting the housing and the hybrid strain separating unit to each other and injecting the desorbing solution 110 into the hybrid strain isolating unit; And a recovering unit for recovering the desorbing solution 120 including the activated sludge that has passed through the hybri-strain isolating unit.

The desalination solution 110 of the treatment tank is injected into the hybrid strain isolator 210 through the infusion section at a constant rate. At this time, the injection unit may be composed of a tube which penetrates the housing and is connected to the hybrid strain separator 210.

The desorption liquid 110 injected at a constant rate through the injection unit is injected into a hybrid strain isolator having a truncated cone structure, and the hybrid isolator is in the form of a truncated cone structure having an upper circle diameter larger than a lower circle diameter So that the desorbing liquid 110 forms a vortex in the inside of the truncated cone structure and can flow downward.

That is, as the desorbing liquid 110 is injected at a constant rate, it flows into the vortex forming portion 210 of the hybrid strain separating portion 210, collides with the inner wall of the vortex forming portion 210, and vortex can be formed. The desorption liquid 110 forms a vortex because the vortex forming portion 210 has a truncated cone structure in which the upper diameter of the upper portion is larger than the lower diameter of the lower portion, have.

When the desorption liquid 110 is formed as a vortex and flows downward, the desorption liquid 110 that has flowed downward passes through the separation membrane 220 located at the lower end of the hybridization isolator and moves to the housing.

The ammonium-oxidized bacterial granules having a particle size larger than the diameter of the pores may not pass through the separation membrane 220, and the inside of the hybrid strain separation unit And the activated sludge having a small particle size and the desorbing liquid 120 containing the activated sludge can move into the housing.

The desorbing liquid 120 may be conveyed to the primary settling tank through the recovery unit of the housing at a predetermined level or higher in the housing.

In addition, ammonium-oxidized bacterial granules remaining in the hybrid strain isolating section are recovered and transferred to the treatment tank 100 (130). The ammonium-oxidized bacterial granules are transferred (130) to the treatment bath (100) and are reusable.

FIG. 3 schematically illustrates the structure of a sewage treatment system according to an embodiment of the present invention. The sewage treatment system of the present invention comprises a primary settler 10 according to the present invention; A biological reaction tank 20, a secondary settling tank 30, a dehydrating tank 40, a digester tank 50, and an SBR reaction tank 60.

In the present invention, after the sewage is supplied to the primary settling tank 10, the foreign substances contained in the sewage are precipitated as raw sludge, and the raw sludge is recovered, and the sewage having the removed biologic material can be supplied to the bioreactor 20. More specifically, when sewage is supplied to the primary settling tank 10, it is separated into a material (raw sludge) layer having a specific gravity greater than that of water and a material having a specific gravity smaller than that of water (suspended material) Approximately 40% of the material can be removed.

In the present invention, the liquid wastewater separated from the raw sludge in the primary settling tank 10 may be supplied to the bioreactor 20.

The bioreactor includes an aerobic unit; A hybrid strain isolator according to an embodiment of the present invention; And an anaerobic tank. More specifically, an aerobic tank for adsorbing organic substances contained in sewage water using activated sludge, the aerobic tank having an inlet for supplying sewage water; A mixing cell for containing sewage and mixing activated sludge; And an aerobic reactor which is continuously connected to the mixed cell and adsorbs the organic material in the activated sludge and sewage. The activated sludge is adsorbed with the organic substances in the sewage, and through this adsorption process, a certain amount of pollutants present in the sewage can be removed in a short time.

In addition, the adsorption process of the activated sludge in the exhalation reaction tank proceeds through the injection of air, and the air injection device is connected to the exhalation reaction tank, so that the air can be injected.

In addition, the exhalation reaction tank is intended to remove contaminants from the sewage water by the activated sludge, so that appropriate environmental conditions for the reaction of the activated sludge in the exhalation reaction tank should be established.

Thus, it is generally important to maintain the temperature in the range of 10 ° C to 35 ° C and to maintain a residence time sufficient for the activated sludge to proceed with the adsorption process, and the pH should be maintained between 6.5 and 8.5.

According to the present invention, the activated sludge is mixed with activated sludge by supplying sewage to be treated through the inlet of the aerobic tank, and reacts with the activated sludge to adsorb organic substances contained in the sewage. At this time, the activated sludge is treated with ammonia oxidizing Archaea ), AOB (Ammonia Oxidizing Bateria) and NOB (Nitrite Oxidizing Bacteria), and adsorbs organic substances through activated sludge.

Further, in the present invention, the mixed cell further includes at least one stirrer, thereby facilitating the mixing process of the sewage and the activated sludge.

In the present invention, the shape of the stirrer is not particularly limited, but may be an impeller type having a blade. Although the shape of the impeller-type agitator is not particularly limited, according to a preferred embodiment of the present invention, the impeller-type agitator is formed such that the outer wing portion is bent toward the lower direction of the inner wing portion, By pushing as much water as possible in the desired direction as if pushing water strongly, it is possible to maximize the stirring effect.

In the present invention, when there are a plurality of stirrers, the blades of the plurality of stirrers may have the same or different diameters, but preferably, the plurality of stirrers having different blade diameters is arranged so as to have a smaller diameter from the upper portion of the chamber toward the lower portion of the chamber The inflow water can be moved from the upper part of the chamber to the lower part to maintain a faster mixing speed.

In this case, the number of revolutions (G-value) of the stirrer blade is not particularly limited and may be appropriately selected according to the size of the agglomeration and agglomeration scale and the size of the chamber, but it may preferably be 30 to 110 sec ^-1 .

Further, in the present invention, an auxiliary agent may be added together with the activated sludge, wherein the auxiliary agent may be selected from the group consisting of clay, calcium hydroxide, a cation flocculant, an anionic flocculant and a non-ion flocculant.

In the present invention, when the activated sludge absorbs the organic substances contained in the sewage water in the aerobic tank as described above and is grown into floc, the treated sewage is supplied to the hybrid strain isolator connected to the aerobic tank 21. The activated sludge adsorbed by the organic substances contained in the sewage can not pass through the separation membrane in the hybrid strain isolation tank and remains as solid sludge. Therefore, in the present invention, the sewage containing flocs can be separated into the primary sludge and the liquid primary treated water through the hybrid strain isolator.

In the present invention, the organic substances contained in the sewage can be adsorbed or agglomerated in the aerobic tank of the bioreactor, and then, in the hybrid strain isolation tank, the sewage can be separated into the primary sludge and the liquid primary treatment water have. At this time, the primary treated water is transferred to the anaerobic tank to proceed with the denitrification process, and the denitrification process in the anaerobic tank is duplicated as described above, so detailed description will be omitted.

According to the present invention, it is possible to separate sludge of a solid phase having a water content of about 70% to 80% from the sewage water by the hybrid strain isolator of the bioreactor 20. Unlike the conventional membrane bioreactor, It is not necessary to provide a separate air injection device for removing the air.

On the other hand, in the present invention, the hybrid strain isolator is the same as the above description, and a detailed description thereof will be omitted. That is, the hybrid strain isolator can be used in combination with the treatment tank of the SBR reaction tank and can be used in combination with the bioreactor 20.

Both the treatment tank and the bioreactor 20 in the SBR reaction tank produce granules using ammonium-oxidizing bacteria, and the resulting granules are too large to pass through the separation membrane in the hybrid strain separation section. The granules which have not passed through the hybrid strain isolation tank of the bioreactor 20 can be recovered and transferred to the previous stage for reuse, and the treated water that has passed through proceeds to the next stage and proceeds with the sewage treatment process. The granules which have not passed through the hybrid strain separating tank 200 in the SBR reaction tank are further transferred to the treatment tank 100 for reuse and the desorbed liquid containing the activated sludge that has passed through the granules is further returned to the first settling tank 10 Transfer it to reuse.

Under the system for sewage treatment, the sewage settles the raw sludge in the primary settling tank 10, separates the liquid wastewater, transfers it to the bioreactor 20, A hybrid strain isolator; And an anaerobic tank, and the organic material removal and denitrification process proceeds.

The second treated water from which nitrogen has been removed from the anaerobic tank stays in the second settling tank 30, the excess sludge is settled and removed, and then discharged through a disinfection process.

The raw sludge and the excess sludge separated and precipitated by the primary settling tank and the secondary settling tank are transferred to the dewatering tank 40, and the dewatering process is performed. The concentrated sludge after the dewatering process is transferred to the digester 50.

In the present invention, the anaerobic digestion process may be performed on the excess sludge and raw sludge using anaerobic microorganisms.

Here, the anaerobic digestion process is also referred to as "methane fermentation", and is a series of processes for converting organic substances contained in the excess sludge into methane by decomposition of various anaerobic microorganisms. More specifically, solid organic matter is liquefied , The process of hydrolysis, the process of producing lower fatty acids (VFA) that produce vinegar acid, propionic acid, and butanoic acid, decomposing them with vinegar acid and H ₂ gas, .

In the present invention, in the digester 50, energy can be recovered by the biogas called methane simultaneously with the treatment of the concentrated sludge. Therefore, in the present invention, it is possible to further include a biogas collector (not shown) for collecting the biogas generated in the digester 50, and if necessary, biogas, which separates methane and carbon dioxide contained in the biogas, And may further include a separator.

In the present invention, when the anaerobic digestion process is performed in the digestion tank 50, digested sludge and desolvation solution, which can not be recycled any more, are generated. In the case of the extinguished sludge, it can be discarded, and the desorbing liquid can be supplied to the SBR reaction tank 60.

The SBR reactor (60) is a sequential batch reactor, which uses a continuous batch activated sludge process. In the conventional SBR process, the reaction and the precipitation of the mixed solution, the drainage of the representative water, and the discharge process of the settled sludge are repeatedly performed by making the reaction tank and the secondary settling tank function in one batch tank.

In the conventional sewage treatment system, after the anaerobic digestion process is carried out using the concentrated sludge in the digestion tank 50, the generated desorption liquid is transferred again to the primary settling tank for reprocessing. However, in this case, the desorbing liquid generated in the digester 50 contains NH ^{4 +} or NO ^{2 -,} and if the sewage treatment is performed in a continuous process, the concentration of nitrogen continuously increases, ) / N (nitrogen) exceeds 1, resulting in a problem that energy production efficiency in the digester 50 is remarkably low.

In order to prevent the above-mentioned problem, the present invention provides a method for removing NH ^{4 +} and NO ² contained in the desalination liquid by transferring the desorbed liquid generated in the digester 50 to the SBR reaction tank 60 and reacting with the anaerobic ammonium-oxidizing bacteria (Anammox) ^- can be converted to N ₂ to remove nitrogen.

In the present invention, the anaerobic ammonium-oxidizing bacteria may be planctomycetes. In general, the AOB bacteria used as the activated sludge in the bioreactor 20 can convert about 50% of NH ^{4 +} to NO ^{2 -} . However, in the present invention, planktonic acid Planctomycetes) may be converted to N ₂ and all of the NH ⁴⁺ NO ^2-. In addition, in the present invention, the planctomycetes adsorb to surrounding organic materials to form granules, wherein the particle size of granules is relatively large compared to AOA, AOB and NOB bacteria And can be selectively separated according to the particle size in the hybrid strain isolator 200 as described above.

In the present invention, as described above, when the nitrogen contained in the desorption liquid is removed in the SBR reaction tank 60, the final treated water generated in the SBR reaction tank 60 is transferred to the first settling tank 10 to perform the sewage treatment process The ratio of C (carbon) / N (nitrogen) in the bioreactor 20 can be maintained at 1, and energy production efficiency can be maintained even in a continuous process for sewage treatment.

In the present invention, the desorbed liquid transferred to the SBR reaction tank (60) can be received inside the treatment tank (100). In the present invention, the desorbed liquid transferred to the treatment tank 100 is anaerobically digested by the anaerobic ammonium-oxidizing bacteria to form granules.

In the present invention, the granules can not pass through the separation membrane module by controlling the pore diameter of the separation membrane to 50 to 150 μm, while bacteria such as AOA, AOB and NOB, which are activated sludge in the bioreactor 20, Lt; / RTI >

In the present invention, the purified effluent and the bacteria such as AOA, AOB and NOB contained therein may be separately recovered and re-supplied to the first settling tank 10 through the treatment water supply pipe.

Hereinafter, the present invention will be described more specifically by way of specific examples. The following examples are provided to aid understanding of the present invention, and the scope of the present invention is not limited thereto.
