摘　　要：采用快速排泥法对悬浮填料和弹性立体填料在常温(18～22℃)下,处理生活污水好氧挂膜的影响因素进行了对比研究。结果表明:在溶解氧充足(DO=3 mg/L)的条件下,进水CODCr浓度为120 mg/L、C/N为5,水力停留时间为6 h时挂膜最优,且悬浮填料的挂膜效果优于弹性立体填料,其对氨氮的去除率达到86%,出水CODCr浓度低于70 mg/L。Using the sludge discharge method, the affecting factors of aerobic biofilm culturing at ordinary temperature of 18-22℃ for sewage treatment with the suspend filler, flexible and stereoscopic filler were contrastively studied. The results showed, when the best working state reached （DO=3 mg/L）, the influent CODcr concentration was 120 mg/L, C/N was 5, HRT was 6 h, and the effect of suspend filler was better than that of the flexible and stereoscopic filler, the removal of NH4^＋-N was 86%, and the effluent concentration was below 70 mg/L.
