摘　　要：采用序批式膜生物反应器处理模拟生活污水,考察其对污染物的去除特性及进水pH对系统去除率的影响。结果表明,进水pH为7～9时,pH变化对污染物的去除率影响不大,COD、NH4+-N、TN、TP平均去除率分别为98.01%、96.51%、73.38%、73.21%,浊度去除率在99%以上。当进水pH降至6时,COD平均去除率仍达95.26%,NH4+-N、TN、TP平均去除率分别降为75.34%、61.42%、62.87%,浊度去除率几乎不受影响,仍在99%以上。In this work,a sequencing batch membrane reactor （SMBR） was operated to treat synthetic domestic wastewater. The characteristics of pollutants removal were studied and the effects of different pH values of raw water on pollutants removal were discussed. The result shows that：when raw water pH values were among 7～9,pH changes had little effect on the pollutants removal rate. The average removal efficiency of COD,NH4＋-N,TN and TP were 98.01%,96.51%,77.38% and 73.21% respectively. Turbidity removal rate was above 99%. When raw water pH value declined to 6,COD average removal rate could be reached 95.26%. NH4＋-N,TN,TP average removal rates were 75.34%,61.42%,62.87% respectively. Turbidity average removal rate was almost not affected,still above 99%.
