Product Description
The basic design idea of MBBR is to be able to operate continuously without blocking and backwashing, with small head loss and large specific surface area. This can be achieved by the biofilm growing on a smaller carrier unit, and the carrier moving freely with the flow of water in the reactor. In aerobic reactor, the carrier is moved by aeration; in anoxic / anaerobic reactor, the carrier is moved by mechanical agitation. In order to prevent the loss of filler in the reactor, a porous filter screen can be set at the outlet of the reactor. MBBR is generally rectangular or cylindrical structure. The rectangular reactor can be divided into several or no grids uniformly along the length of the tank with baffles. Generally speaking, the flow in the reactor is push flow, and in each cell, due to aeration fluidization, the flow is completely mixed. The specific gravity of the tank is close to that of water, polyethylene or polypropylene suspended filler with large specific surface area. The attached surface of biofilm in the reactor can reach 500m2 / m3, and the actual specific surface area (inner surface of filler) can reach 350m2 / m3. The perforated aeration pipe is aerated on one side to make the packing circulate in the tank. The bottom of the cylindrical reactor is provided with a microporous aeration head. In addition, some reactors are equipped with not only aeration device but also agitation device. These agitation devices can make the reactor easily and flexibly used in the anoxic state.

Advantages
1. The effect of biological phosphorus removal is good. The influent of anaerobic zone includes the mixture of total influent and backflow from anoxic zone II, and the mixture at the end of anoxic zone II. Due to the full denitrification and phosphorus accumulation reaction, the concentration of nitrate is low. After backflow to anaerobic zone, the anaerobic phosphorus release and storage energy of phosphorus accumulating bacteria will not be affected, so as to fully ensure the effect of biochemical phosphorus removal;
2. The denitrification volume load is high. Different from the traditional secondary treatment process, the sedimentation area is set at the end of the process section. The sedimentation area of the sewage treatment system of the invention is set in the middle of the process section. The effluent is not the final effluent. There is no need to worry that the sludge concentration entering the sedimentation area is too high, resulting in the effluent SS exceeding the standard. Therefore, the anoxic area can be allowed to have high sludge concentration under the same sludge load The volume load is higher;
3. The carbon source and energy are fully utilized, one carbon is multi-purpose. First, the backflow setting of the sewage treatment system of the invention can utilize the characteristics of DPB denitrifying phosphorus accumulating bacteria for simultaneous denitrifying phosphorus removal. The phosphorus accumulating uses nitrate nitrogen as the electronic receptor, one carbon is dual-purpose. In addition, the high concentration sludge in anoxic zone is conducive to the precipitation of internal carbon source, which can make more use of the internal carbon source of the system. When the carbon source of influent water is insufficient, the external carbon source can be saved. After the sedimentation area is located in the anoxic area, the sludge does not pass through the aerobic area, avoiding the aerobic degradation of carbon source, and can enter into the sludge, improving the value of sludge resources and energy recovery, and the utilization of phosphorus is the combined oxygen No3, reducing the demand for dissolved oxygen and reducing energy consumption;
4. Nitrification is sufficient and the load is high. After passing through the sedimentation area, the supernatant enters the biofilm area. Because the suspension carrier is blocked in the fixed area by the screen, it is beneficial to the attachment and growth of microorganisms with long mud age, especially the nitrobacteria and nitrobacteria. The nitrification effect is good, and the ammonia nitrogen in the sewage can be fully nitrated;
5. There is only a kind of biofilm on the suspension carrier in the biofilm area, which is simple in operation, management and control, and high in nitrification load. At the same time, using the multilayer structure of biofilm can provide favorable conditions for simultaneous nitrification and denitrification, and enhance the removal effect of nitrogen;
6. The sewage treatment system of the invention is provided with a sedimentation area in front of the biofilm area. After sedimentation, the supernatant enters the biofilm area. The nitrification process depends on the microorganism attached to the suspension carrier in the pool. The SS concentration of the effluent is far lower than that of the activated sludge mixture, which can reduce the filtration pressure of the membrane, improve the membrane flux, and reduce the frequency of membrane washing and cleaning Prolong the service life of the membrane;
7. The sludge concentration in anaerobic area and anoxic area is high, the biofilm area relies on carrier efficient nitrification effect, the volume load is very high, and the tank capacity is saved. The final sludge water separation effluent adopts membrane filtration, which has good effect of land occupation and high system integration. Although it has good removal effect on all indicators, the land occupation is high Very economical;
8. It is widely used in the new construction, reconstruction and integrated sewage treatment equipment of sewage plant.
