摘　　要：为综合分析污泥浓度对MBSBBR处理城镇污水中有机污染物的影响,考察了四种不同污泥浓度对MBSBBR系统COD,NH4+-N,TN,TP去除效果的影响。结果显示,MBSBBR系统COD的降解随着污泥浓度降低存在微弱下降趋势;污泥浓度变化对硝化脱氮效率没有明显影响;TP去除效果随MLSS变化显著,MLSS减少,TP去除率降低。综合考虑污水有机物的去除效率以及耐负荷能力,MBSBBR处理城镇生活污水可选在1.5-2 g/l.In order to comprehensively analyze the influences of the sludge concentration on MBSBBR for treat-ment of the organic contaminants in the urban domestic sewage and four different sludge concentrations are inves-tigated to check the influences on the removal effect of COD, NH4^＋-N,TN,TP in MBSBBR system. The results show that the degradation of COD in MBSBBR system falls with the reduction of sludge concentration slightly ; the changes of the sludge concentration shows no obvious influence on the nitrifying denitrogenation efficiency; TP- removing effect becomes obvious with the changes of MLSS, namely TP-removing ratio falls when MLSS decrea-ses. Comprehensively considering the removal efficiency and load-proof impact capacity of the organic substances in the sewage, 1.5-2g/1 can be chosen for MBSBBR to treat urban domestic sewage.
