MBR membrane bioreactor
The phase overview of MBR membrane bioreactor is as follows
Firstly, because of its effective trapping effect, microorganisms with a longer period can be retained, which can complete the deep purification of sewage. At the same time, nitrifying bacteria can fully propagate in the system. Its nitrification effect is significant and it may provide deep phosphorus and nitrogen removal.
MBR membrane bioreactor is a new type of wastewater treatment technology combining membrane separation technology with biotechnology. It uses membrane separation equipment to capture activated sludge and macromolecular organic substances in the biochemical reaction tank, eliminating the need for a secondary sedimentation tank. The activated sludge concentration is thus greatly increased, and the hydraulic retention time (HRT) and sludge retention time (SRT) are controlled separately, and the refractory substances will continue to degrade in the reactor.
Therefore, the membrane bioreactor process is through membrane separation technology, which greatly strengthens the function of the bioreactor. Compared with traditional biological treatment methods, it has high biochemical efficiency, strong load shock resistance, stable effluent water quality, and covers an area Small area, long sludge discharge period, easy to complete automatic control, etc. Among them, the quality of two-stage reverse osmosis equipment is more outstanding.
It has a wide range of applications including sewage reuse in hotels, restaurants, domestic sewage, industrial and mining enterprises, remote rural areas, and tourist attractions. At the same time, there are various industrial wastewaters that have similar properties to domestic sewage, such as hospital wastewater, pharmaceutical wastewater, scrubbing wastewater, food wastewater, and cigarette wastewater.
