1) High removal rate of pollutants, strong resistance to sludge expansion, stable and reliable 4outlet water quality, and no suspended matter in the outlet water.
2)The membrane bioreactor realizes the separate control of the reactor sludge age SRT and hydraulic retention time HRT,so the design and operation are greatly simplified.
3)The mechanical interception of the membrane avoids the loss of microorganisms. The bioreactor can maintain a high sludge concentration,which can increase the volume load, reduce the sludge load, and has a strong impact resistance.
4)Since the SRT is very long, the bioreactor has played the role of "sludge nitrification tank",thereby significantly reducing the sludge output,the excess sludge output is very low, and the sludge treatment cost is low.
