The present invention will be described below in connection with FIGS. 1 and 2.

That is, by connecting the lower portion of the anaerobic tank 50, the treatment water outlet 53 is formed in the upper portion with the bottom of the aeration tank 70, to remove the relatively large contaminants and suspended solids in the screen tank 10, the flow rate control Homogenized wastewater containing high concentrations of nitrogen, such as livestock wastewater and manure, introduced into the tank 20 to continuously introduce a constant amount into the aeration tank (70).

Wastewater, such as livestock wastewater and manure, introduced into the aeration tank 70 is introduced into the lower portion of the anaerobic tank 50 through the aeration tank 70, and the activated sludge in the mixed solution is filtered by a sludge layer formed in the anaerobic tank 50. The upper part of the anaerobic tank 50 is formed with a filtered and separated liquid layer to be continuously discharged to the next step through the treated water outlet (53).

On the other hand, the anaerobic tank 50, as shown in Figure 4, the inside of the anaerobic tank 50, the stirrer 80 is formed with a plurality of impeller 81 formed in a mesh or bar shape is slowly driven for the overall reaction ) By stirring the inside of the anaerobic tank at a speed of 0.1 to 30 m / min, preferably 0.1 to 2 m / min, stirring the inside of the anaerobic tank evenly and inducing the overall reaction inside the anaerobic tank to discharge nitrogen gas. Facilitate the management of anaerobic sludge.

The impeller 81 which is rotated in a slow motion for the overall reaction in the anaerobic tank 50 is formed in a mesh shape, so that the anaerobic sludge can be easily filtered off, or the impeller 81 is formed in a bar shape. This makes it possible to crush anaerobic sludge of relatively large size.

At this time, the reaction and the principle of the removal of contaminants in aerobic and anaerobic and anaerobic conditions are as follows.

Nitrogen in wastewater such as livestock waste and manure is in the form of organic nitrogen (Org-N), ammonia nitrogen (NH ₃ -N), nitrous nitrogen (NO ₂ -N) and nitrate nitrogen (NO ₃ -N) The main forms of wastewater, such as untreated livestock wastewater and manure, are organic nitrogen and ammonia nitrogen. In the early stages of pollution, the nitrification process is carried out mainly as ammonia nitrogen and then oxidized to nitric acid in an aerobic state as the contamination is restored.

Biological nitrification in wastewater treatment processes such as livestock wastewater and manure is carried out by two species, Nitrosomonas, which oxidizes ammonia nitrogen to nitrite nitrogen, and Nitrobacter, which oxidizes nitrite nitrogen to nitrate nitrogen. These microorganisms are autotrophic organisms because heterotrophic organisms obtain energy from oxidizing organic compounds while energy from inorganic compounds.

Nitrification of ammoniacal nitrogen consists of two steps. The first step is the conversion of ammonia nitrogen to nitrite nitrogen by Nitrosomonas, and the second step is the conversion of nitrite nitrogen to nitrate nitrogen by Nitrobacter.

^{_{NH 4 + + 1.50 2 → NO}} 2 - + H 2 O + 2H +

^{_{NO 2 - + 0.5O 2 → NO}} 3 -

In the above scheme, oxygen is the electron transporter of biochemical oxidation of ammonia nitrogen and nitrite nitrogen. Oxygen is the only electron carrier available to Nitrosomonas and Nitrobacter. Therefore, aerobic conditions are essential for the nitrification process to proceed, and the denitrification process is to remove the oxidized nitrate ions by NO, N ₂ O, and N ₂ .

Microorganisms involved in denitrification include Achromobacter, Bacillus, Brevibacterium, Enterobacter, Lactobacillus, Micrococcus, Paracalobactrum, Pseudomonas, and Spirillum. These microorganisms are heterotrophic organisms. They are aerobic, breathable anaerobic, anaerobic, etc., but more than 80% in nature are known as breathable anaerobic, and these microorganisms use oxygen as an electron transporter to oxidize organic compounds. In this case, as the final electron acceptor, oxygen (NO ₃ ⁻ , SO ₄ ^2-, etc.) in a chemically bonded form is used. Thus, when there is no dissolved oxygen (molecular oxygen) and only oxygen in a chemically bonded form is called anoxic condition, it is distinguished from anaerobic condition. The presence of oxygen in the anaerobic state controls the action of oxygen in the breathing of the anaerobic microbial organisms, which is much more energetic when using dissolved oxygen than chemically bound oxygen as the final electron acceptor. This is because they prefer dissolved oxygen. Therefore, there must be no dissolved oxygen (molecular oxygen) for denitrification.

All processes for biological phosphorus removal maintain the periodic anaerobic / aerobic state of the reactor, ie phosphorus removal using phosphorus release and luxury uptake.

Phosphorus-removing microorganisms (PAOs) use the energy generated when decomposing the inorganic phosphorus (Poly-P) in the cell under anaerobic conditions, ingesting organic acids such as acetic acid, and then passing them on to PHA (Poly Hydroxy Acetate). In this case, free phosphate (Ortho-P) is released into the solution, which is called Phosphorus release. When the anaerobic condition is changed from aerobic condition, the phosphorus-removing microorganism decomposes the stored PHA, synthesizes ATP (Adenosine Tri-Phosphate), and uses it to ingest phosphate from the solution to synthesize it as an inorganic phosphorus and store it in the cell.

It is also important to note that the presence of other electron acceptors, ie NO ₃ ⁻ , in addition to oxygen, such as phosphorus excess intake in aerobic conditions, impedes the release of phosphorus in the absence of oxygen. In anaerobic baths, the release of phosphorus requires NO ₃ ⁻ to be effective.

The wastewater treatment apparatus such as livestock wastewater and manure according to the present invention performs intermittent aeration at different times according to the characteristics of the wastewater such as livestock wastewater and manure flowing in the aeration tank 70, so that the aeration is included in the influent during the aeration time. The ammonia nitrogen thus obtained is oxidized to oxygen nitrate by oxygen and nitrate bacteria, and in particular, the anaerobic and anaerobic sludge layers formed in the anaerobic tank 50 are introduced into the lower part of the anaerobic tank 50 to the stirrer 80. By stirring the mesh or bar-shaped impeller 81 at a slow speed of 0.1 to 30 m / min, the anaerobic sludge is easily managed while inducing a reaction to the entire anaerobic tank 50 to facilitate the discharge of nitrogen gas. By doing this, the nitrate nitrogen (NO ₃ -N) oxidized in the aeration tank 70 can be removed by reducing with nitrogen gas (N ₂ ↑).

Phosphorus is also consumed by the Poly-P microorganism in the anaerobic state by using short-chain fatty acids to release phosphorus and then ingesting excess phosphorus again during the aeration time. Removal of phosphorus and removal of phosphorus throughout the system is by disposal of excess sludge.

In order to remove nitrogen in a mainstream process such as an A ² / O process, an internal recycle of the sludge mixture of the aeration tank 70 containing nitrate nitrogen to the anoxic tank 60 is necessary. The sludge that has undergone solid-liquid separation in the final sedimentation tank 80 requires sludge transfer to the front end of the process for replenishing the amount of microorganisms in each reactor or returning sludge to the anaerobic tank 50, and in the present invention, the anaerobic tank By filtering by the sludge layer formed in the 50, the aeration tank 70 can be operated by maintaining a high sludge concentration (high concentration microorganism), so that the site is saved when constructing wastewater treatment facilities such as livestock wastewater and manure, and construction cost is low. In addition, wastewater, such as livestock wastewater and manure containing high concentrations of nitrogen, phosphorus and organic matter, as well as sewage with low organic matter concentration and C / N ratio, can be effectively treated.

As described above, the sewage / wastewater treatment apparatus according to the present invention is the same as the conventional apparatus from the sewage / wastewater inlet 12 to the flow control tank 20, but a partition wall defining the anaerobic tank 50 on one side of the aeration tank 70 is provided. (52) is integrally formed so that its upstream end is higher than the surface of the wastewater such as livestock wastewater and manure, at this time, the anaerobic anaerobic and inflow into the lower portion of the anaerobic tank (50) formed in the anaerobic tank (50) The anaerobic sludge layer is stirred by rotating the mesh or bar-shaped impeller 81 of the stirrer 80 at a slow speed of 0.1 to 30 m / min.

In addition, an elliptic-shaped pellet container 120 (Pellet) is provided on the upper side of the air outlet 110, which is installed in the plurality of air outlets 110 to the lower side of the aeration tank 70 through the triangular support 121. At this time, by forming the wire mesh 122, 123 (Mesh) on the lower and upper main surfaces of the pellet container 120, by the air blowing in the air outlet 110, the waste water / waste water After flowing into the pellet container 120 through the lower wire mesh 122, the wire mesh 123 flows out to the outside by the wire mesh 123 formed on the upper main surface of the pellet container 120 to perform a stirring action.

On the other hand, the inside of the pellet container 120 has a microbial active inducer for inducing the activation of microorganisms for treating contaminants such as livestock wastewater and manure, the wire mesh 123 upper lid of the pellet container 120 Opening and filling the inside, wherein the microbial active inducer 33% by weight of organic matter remaining in the soil, SiO ₂ 53.4% by weight, Al ₂ O ₃ 7.8% by weight, Fe ₂ O ₃ 4.0% by weight, Na ₂ O 0.5 weight %, K ₂ O 0.3% by weight, CaO 0.5% by weight, MgO 0.5% by weight.

Therefore, the aerobic and anaerobic sludge layer formed in the anaerobic tank 50 as described above, while stirring with a stirrer 80, the microorganism active inducer filled in the pellet container 120 of the aeration tank 70 and By contacting and activating microorganisms in the sewage / wastewater, the aeration tank 70 oxidizes and decomposes pollutants by the activated aerobic microorganisms, and in the anaerobic tank 50, organic substances and nitrogens by the anaerobic and anaerobic microorganisms, It is possible to easily manage aerobic sludge and anaerobic sludge while inducing the reaction of removing phosphorus to facilitate the discharge of nitrogen gas.

As described above, according to the present invention, a wastewater treatment apparatus and method containing high concentrations of nitrogen such as livestock wastewater and manure are formed by forming an anaerobic tank having a sludge layer formed in the aeration tank integrally to oxidize and decompose contaminants in an aerobic state. The removal of organic substances and nitrogen in the anaerobic state and the removal of sludge ingesting excessive phosphorus simultaneously removes phosphorus, as well as the characteristics of wastewater containing high concentrations of nitrogen such as livestock wastewater and manure and the required treatment quality. Therefore, by repeating the process in a single or multi-stage, not only to improve the treatment efficiency, but also to stir the rotation of the mesh or bar-shaped impeller of the agitator installed in the anaerobic tank at a slow speed evenly stir the inside of the anaerobic tank, the lower side of the aeration tank Above the air outlet, which is installed in plural for the flow of wastewater The wire mesh is formed on the lower and upper main surfaces of the elliptic-shaped pellet container filled with the microorganism induction agent, and the lower / waste water enters into the pellet container and performs stirring to discharge to the outside.
