mbr municipal wastewater treatment of a process, process details can be referred to Baidu encyclopedia web link
Main innovations:
1. Carrier using nano-polyurethane, with a large bio-carrying capacity, biological species, the carrier outside the growth of aerobic microorganisms, and the growth of anaerobic microorganisms within the growth of the carrier.
2. The water outlet end of the reactor adopts the overall polyurethane porous biofilm instead of the conventional polymer ultrafiltration membrane, which utilizes the microorganisms propagated in the membrane pores to adsorb and degrade the organic matter and ensure the quality of the water outlet. It is characterized by low price and good quality of effluent water.
3. Biofilm has a long service life, no late replacement of the membrane costs, cheap equipment, low water production costs.
Main advantages:
1. small investment in the system, occupying a small area
2. modular combination, easy installation of equipment
3. long service life of the biofilm
4. high degree of automation
5. low operating costs
6. fast startup, no sludge, no odor

MBR biofilm sewage treatment system consists of the main equipment and selected disinfection, phosphorus removal system **** with the composition.
1, the main part of the equipment adopts MBR wastewater biological treatment technology, the biological treatment technology consists of two core technologies:
One lies in the combination of biofilm technology and microbial immobilization of composite biofilter technology, OD, BOD, SS,
NH3-N and other major pollutants with high removal efficiency. Immobilized biofilter in the polymer carrier, the formation of surface aerobic, internal anaerobic microbial composite mode, sewage in the composite biofilm reactor through the repeated aerobic anaerobic treatment, to obtain the maximum biodegradation effect.
The second is the use of biofiltration membrane as a guarantee of terminal water quality treatment of the effluent. The biofilm replaces the expensive polymer membrane in the traditional membrane bioreactor process, which reduces the cost of the equipment and the replacement cost of the membrane. At the same time, all the sewage is forced to pass through the biofilm, and the mechanical filtration, biological adsorption and biodegradation of the biofilm are utilized to further remove the small amount of organic pollutants left in the effluent water, and the effluent water quality is significantly better than that of the conventional biological treatment system, and it can be ensured to meet the standard of reuse of water.
2, the disinfection system can be optional according to the demand for reuse, can be equipped with ultraviolet disinfection, ozone disinfection and other different configurations according to customer demand.
3, phosphorus removal system for the water landscape water when selected, including dosing device and precision filter, filter backwash water discharged to the septic tank.
4, the automatic control system is an integrated equipment technology support, can realize the full automatic operation of the whole set of equipment. The automatic control system can guarantee the safe operation of the system through the linkage and switching of each control point, meanwhile, it has the function of sound and light alarm and intelligent signal remote transmission.
