摘　　要：将一体式膜生物反应器与序批式活性污泥法相结合而构建了M-SBR工艺。采用该工艺处理模拟生活污水,通过调节反应器的厌氧、好氧和缺氧时间比例,使系统分别按照AO-MSBR和AOA-MSBR的方式运行,考察了在相同操作条件下,系统对COD、氮、磷的去除效果。试验结果表明:AOA-MSBR工艺比AO-MSBR工艺具有更好的同步脱氮除磷效果,其对COD的平均去除率达到了98.5%,对氨氮的平均去除率达到了90.3%,对总氮的平均去除率达到了89.5%,对总磷的平均去除率为88.5%。The combined process of integrated membrane bioreactor and sequencing batch sludge process was adopted to treat simulated domestic wastewater. Through adjusting time of the anaerobic, aerobic and anoxic stages, the system is capable of operating in AO-MSBR and AOA-MSBR modes respectively. The removal efficiencies of COD, nitrogen, phosphorus under the same operation conditions were investigated. The results indicate that the AOA-MSBR exceeds the AO-MSBR in simultaneous nitrogen and phosphorus removal. The removal efficiencies of COD, NH3 - N, TN and TP by the AOA-MSBR are 98.5% , 90.3% , 89.5% and 88.5% respectively.
