The treatment of car-washing wastewater by using membrane bioreactor was investigated. The influences of operating pressure and environmental factors on the membrane's filtration function were analyzed combining with theoretical calculations. In the meiobar range, membrane resistance was the dominant role, independent of operating terms. In the middle pressure range, concentration difference-polarized resistance was the dominant role, depending much on operating terms. In the high pressure range, gelatin resistance was the dominant role. The influences of the operating pressure was small on the membrane flux, and the membrane's separating characteristics were related much with mud concentration, membrane flow velocity and etc.

通过膜生物反应器处理某车辆厂洗车废水的实验研究，结合理论计算，分析了操作压力及环境因素对膜过滤性能的影响研究结果表明，在低压区，膜本身阻力占主导地位，它与操作条件无关；在中压区，浓差极化阻力占主导地位，它与其他操作条件关系密切；在高压区，凝胶层阻力占主导地位，操作压力增加对膜通量影响不大，在此阶段膜分离特性还与污泥浓度、膜面流速等操作条件有关。

In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.
