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.
