摘　　要：采用九保田板式膜,设计了二段淹没式膜生物反应器处理城市生活污水.运行结果显示,二段淹没式膜生物反应器能够增强高能级生物体蠕虫生长与少产污泥的目的.在污泥负荷为0.35～0.65 g[COD]/(g[SS]·d)和容积负荷为2～5 g[COD]/(L·d)的条件下,反应器出水COD和NH3-N的质量浓度分别为18.67 mg/L和0.24mg/L,污泥产率为0.1 kg[SS]/kg[COD].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.
