The present invention relates to an advanced treatment apparatus and method for wastewater using active soil microorganisms, and more specifically, to a new biological process that can increase the efficiency of nitrogen and phosphorus removal, as well as removing odors of wastewater through simple process changes in the wastewater treatment plant. An advanced treatment apparatus and method for wastewater using active soil microorganisms providing a treatment process.

In general, the method used so far to remove the odor and nutrients of the waste water is a situation that is used in the field by combining the deodorization technology and nitrogen and phosphorus removal technology developed in the past.

That is, the wastewater itself or the odor generated in the process of treating it are physical treatment methods (washing method, activated carbon adsorption method, air dilution method), chemical treatment method (oxidation method, chemical liquid cleaning method, neutralization method, combustion method, ion resin exchange method), biological treatment method. (Scrabber deodorization, aeration tank deodorization, soil deodorization, compost deodorization, pit deodorization, packed tower deodorization) is selected and applied to remove nitrogen and phosphorus. Among the A2 / O method, UCT method, VIP method, and SBR method that combine the aerobic process, it is applied considering local conditions and economic feasibility.

The main components of odor generated in sewage treatment plant are ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, etc. In order to remove them, the most commonly applied method in domestic sewage treatment plant is soil deodorization method and adsorption method. It is reflected.

The soil deodorization method is to reduce the odor by a complex action such as passing the malodorous material through the soil layer, absorption of pore water, adsorption of soil particles, biochemical decomposition by soil microorganisms and neutralization by chemical reaction with soil components. How to remove.

In addition, the soil deodorization method is low in operating costs, easy to maintain, and has the advantage of being able to handle a high concentration of odor for all odors, but a large land area is required to reduce the pressure loss due to high ventilation resistance Therefore, it is not only limited to installation in places where it is difficult to secure the site, such as urban areas, but also likely to close soil voids and short-circuit during rainfall, especially in cold districts. There are disadvantages.

On the other hand, the adsorption method is to remove the odorous substances by adsorbing activated carbon, ion exchange resin, etc. The adsorbents are classified into acidic, basic, and neutral based on the type of deodorant, and can be applied to various odorous gases by combination of adsorbents. The range of the object is wide.

In addition, since the deodorizing effect is very high, it is widely applied as a method of removing the residual odor treated in the primary treatment and combination treatment with other methods.

However, for high concentration of odor, there is a problem in that the service life of the adsorbent is shortened due to the limitation of adsorption capacity, a problem of generating secondary pollutants after treatment, and facility and maintenance costs are high.

The aeration tank deodorization method can minimize the installation cost because it uses the aeration tank operating in the existing wastewater treatment plant, there is an advantage that the range of odorous substances are wide, but activated sludge odor can not be used alone, activated carbon There is a disadvantage that it is necessary to process the back posture, and it is limited by the processing air volume because the pressure loss is large.

In addition, the above method has a disadvantage in that the removal rate of poorly soluble odorous substances is low because the gas-liquid contact time is short, and the ability to respond to variations in odorous components is slow.

On the other hand, when odorous substances are injected into the activated sludge in the aeration tank, there is a possibility that the treatment water, the substrate of the activated sludge and the biohazard may be adversely affected. Therefore, a limit injection concentration that does not affect the water treatment should be determined. There are not many examples.

However, when directly injected into a high concentration of odor, it is known to affect the sedimentation of the sludge due to the growth of filamentous microorganisms.

Methods for biologically removing nitrogen and phosphorus in sewage water include the A2 / O method, the UCT method, the VIP method, and the SBR method.

The principle of removing nitrogen and phosphorus in sewage water using these methods is as follows.

That is, the ammonia nitrogen introduced into the process should be oxidized to nitrate nitrogen by nitrifying bacteria such as Nitrosomonas and Nitrobacter under aerobic conditions, and the oxidized nitrate nitrogen is anaerobic or Under anoxic conditions, it is reduced to nitrogen or nitrous oxide gas by the action of denitrification bacteria such as Pseudomonas, Micrococcus and Bacillus, and is removed while being released into the atmosphere.

In the case of phosphorus, the mechanism of its elimination is not yet clear, but the removal of phosphorus from the wastewater by biological treatment starts with the release of phosphorus at the time of anaerobic storage and the accumulation of cell growth and polyphosphoric acid under aerobic conditions. do.

Microorganisms involved in the removal of phosphorus are known as Acinetobacter, Aeromonas, Pseudomonas and the like.

The above A2 / O method, UCT method, and VIP method combine anaerobic-oxygen-aerobic tank to remove nitrogen while reducing ammonia nitrogen by microorganisms in the aerobic tank at the end of the process, and phosphorus in the aerobic tank of the process. Phosphorus is removed by discarding the excess microorganisms.

In particular, in the case of the UCT method and the VIP method, in order to minimize the effect of nitrate nitrogen when the phosphorus is released from the anaerobic tank at the front end of the process, the oxygen tank is returned and operated from the anaerobic tank to the anaerobic tank.

However, if the operation of this process is selected, microorganisms that released phosphorus in the anaerobic tank are returned to the anaerobic tank in the aerobic tank without proliferation of cells and excessive intake of phosphorus, resulting in a decrease in phosphorus release and intake capacity, resulting in a high efficiency of phosphorus removal. Falling, there are a lot of internal transport, there is a disadvantage that the construction cost for the installation increases, facility maintenance management costs increase.

In addition, there is an SBR method that eliminates internal transport and removes nitrogen and phosphorus by separating anaerobic, anaerobic, and aerobic conditions according to time, not spatial movement, in a single reactor.

This process has the advantage that the initial investment costs are inexpensive because the reaction and precipitation occurs in one reactor at the same time, if the precipitation state of microorganisms in the reactor is not good, the effluent quality is likely to deteriorate.

When the above methods are applied to deodorization and nitrogen and phosphorus removal of sewage water treatment plant, since the advanced treatment process and the deodorization facility are separately constructed and operated in conjunction, the installation site, construction cost, and maintenance cost are excessively required. In addition, highly specialized knowledge is required for the stable operation of two separate processes.

In addition, there is a problem that it is difficult to deal with the situation for the inflow or impact load of harmful substances above the allowable concentration in the biological deodorization facility or the advanced processing process, and it takes a long time to stabilize the system.

Therefore, in order to solve this problem, a pretreatment apparatus including a flow adjusting tank for removing suspended solids in wastewater and equalizing the flow rate and water quality of the influent wastewater, an initial settling tank for sedimenting and removing solid particles of influent wastewater, and odor and nutrition of wastewater A culture tank for cultivating soil microorganisms to remove salts, a culture sludge return line for removing odor from the wastewater inflow point, an anaerobic tank for releasing phosphorus under anaerobic conditions, and nitrification, denitrification, phosphorus in aerobic and anoxic states Intermittent aeration tank to induce excessive intake, intermittent internal conveying line to return to the front end from the intermittent aeration tank to enhance the denitrification efficiency, and the treated liquid is separated into solids to circulate part or all of the sludge into the culture tank and anaerobic tank Auxiliary devices such as deodorization equipment, including the final sedimentation tank for Although the wastewater treatment plant has been promoted to remove odors and treat nitrogen and phosphorus through simple process changes without additional installation, it also requires sufficient time to cope with the inflow of nitrogen and phosphorus at high concentrations. It is becoming.

In addition, there is a risk of leakage of PIN FLOC in the sedimentation tank due to the weakening of the compaction of FLOC, and the consumption of fillers is high, which leads to an increase in the management cost during maintenance, and the addition of a separate culture tank adds a separate culture tank to the aerobic tank in the aging state. This can lead to lower active forces.

In addition, since the microbial activity is reduced, a lot of site area is required at the time of design, and it is difficult to secure stable water quality due to problems such as an increase in construction cost.

Therefore, the present invention has been invented to solve the above problems, to lower the load of organic matter in the fluid in the reaeration tank, to remove the nitrogen and phosphorus by maintaining the fluid in an oxygen-free state in the degassing and denitrification tank, microbial activation By forming a tank to include strong organic matter resolution, and to include a device and a process for the formation of sufficient nitrate and phosphate in the nitrification tank, elimination of odors and organic pollutants in sewage water, as well as the cause of eutrophication It is an object of the present invention to provide an advanced treatment apparatus and method for wastewater using active soil microorganisms, which provides a new biological treatment process for improving the treatment efficiency of nutrients such as nitrogen and phosphorus.
