在以复合式膜生物反应器系统为基础，以模拟城市污水为处理对象。通过运行条件优化研究，系统获得了良好的出水水质，出水中SS、浊度及色度均未检出；出水中有机污染物和N、P的平均浓度分别为COD≤16．32mg／L、BOD5≤3．45mg／L、NH3-N≤0．75mg／L、TN≤10．13mg／L、TP≤1．08mg／L，其相应的平均去除率分别为≥95．58％、≥98．91％、≥97．19％、≥71．71％、≥71．31％，各项水质指标的去除率明显高于传统生物处理工艺。优良的出水完全能满足城市生活杂用对水质的要求。
在以複閤式膜生物反應器繫統為基礎，以模擬城市汙水為處理對象。通過運行條件優化研究，繫統穫得瞭良好的齣水水質，齣水中SS、濁度及色度均未檢齣；齣水中有機汙染物和N、P的平均濃度分彆為COD≤16．32mg／L、BOD5≤3．45mg／L、NH3-N≤0．75mg／L、TN≤10．13mg／L、TP≤1．08mg／L，其相應的平均去除率分彆為≥95．58％、≥98．91％、≥97．19％、≥71．71％、≥71．31％，各項水質指標的去除率明顯高于傳統生物處理工藝。優良的齣水完全能滿足城市生活雜用對水質的要求。

Based on the hybrid membrane bioreactor（HMBR） system, this paper takes simulated municipal wastewater as treat- ment subject. Better effluent quality was obtained through optimizing the operation conditions. The results show that the filtrate turbidity, SS and color are not founded in the effluent. The average COD, BOD, NH2 - N, TN and TP removal by the HMBR was as high as 95.58 % ,98. 91% ,97.19% , 71.71% and 71.31% , and resulting in the residual in the filtrate is 16. 32 mg/L,3.45 mg/ L, 0. 75 mg/L,10. 13 mg/L and 1.08 mg/L. These results meet the requirements of national secondary emission standard.
