| Abstract: | A two-stage, submerged membrane bioreactor with Kubota flat-plate microfiltration membrane was designed for the treatment of municipal domestic waste water. The results of the operation showed that the two-stage, submerged membrane bioreactor helped the growth of the energy-rich worms and reduced the yield of sludge. When the sludge loading was 0.35 ~ 0.65g/(g·d)and the volumetric loading was 2 ~ 5g/(L·d), the mass concentrations of COD and NH3-N of the effluent water were 18.67 mg/L and 0.24 mg/L respectively, and the sludge yield was 0.1 kg/kg. |
