Membrane bioreactor in middle-water recycle process has a problem of sludge bulking, it is found through the practical operation that: deficiency of nitrogen in raw water is the main cause of sludge bulking. In period of sludge bulking, ferrous sulfate may be used as emergency-feeding coagulart in membrane bioreactor process, while, the radical solution is that increasing the organic loading and adjusting the ratio of nutrient materials at the same time. The engineering practice proves that, the control of ...
