摘　　要：本文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,综合脱氮除磷效果及经济因素,将复合区水力停留时间控制在7h左右。此时系统总去除率为:CODcr≧96.28%、NH3-N≧97.54%、TN≧74.87%、TP≧74.34%,出水可以稳定保证在CODcr≦14.35mg/L、NH3-N≦0.74mg/L、TN≦9.02mg/L、TP≦1.05mg/L。效果较好。The article proposes to treat with municipal wastewater based on the hybrid mem- brane bioreactor. Hydraulic retention time （HRT） can be controlled for 7h by optimization of running conditions, and comprehensive consider of nitrogen and phosphorus removal efficiency and eco- nomic factors. At that time, the average COD, NH3 - N, TN and TP removal rate are as high as 96.28%, 97.54%, 74.87% and 74.34%, and the average COD, NH3 - N, TN and TP of effluent are as low as 14.35mg/L, 0.74mg/L , 9.02mg/L and 1.05mg/L.
