中文摘要：

采用一体化膜生物反应器（IMBR）工艺处理农村生活污水,考察了该工艺对COD、BOD5、NH3-N和浊度的去除效果。结果表明,在水温〉22℃、ρ（DO）〉3.4 mg.L-1、pH在6～9的条件下,工艺对COD、BOD5、NH3-N和浊度的去除效果较好,平均去除率分别达到93.1%、95.3%、93.8%和97.9%,出水COD、BOD5、NH3-N的质量浓度、浊度分别为19～31 mg.L-1、5.1～7.8 mg.L-1、1.9～3.1 mg.L-1、0～1 NTU,水质优于GB 5084-2005要求。

英文摘要：

The integrative membrane bioreactor（IMBR） was applied for treatment of rural domestic sewage.The removal efficiencies of COD,BOD5,NH3-N and turbidity in the combined process were investigated.The result showed that the combined process may achieve better removal efficiencies of COD,BOD5,NH3-N and turbidity when water temperature was above 22 ℃,ρ（DO） was above 3.4 mg·L-1 and pH was between 6 and 9.The removal efficiencies of COD,BOD5,NH3-N and turbidity in the combined process were more than 93.1%,95.3%,93.8% and 97.9% respectively.The effluent COD was 19～31 mg·L-1,BOD5 was 5.1～7.8 mg·L-1 and ρ（NH3-N） was 1.9～3.1 mg·L-1,turbidity was 0～1 NTU.It was better than that of standard＇s for irrigation water quality（GB 5084-2005）.
