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。

Experimental results showed that, in this process, the optimal pH of the shortcut nitrification was 8.0～8.5; when the pH was less than 6,the nitrification is completely inhibited; when the pH was 6～7, at the end of aeration, the Nitrobacteria become the dominant bacteria because of the dropping of the free ammonia concentration. It is known to all, the activity of the Nitrobacteria and Nitrosomonas was affected by FA concentration, so nitrification was affected by FA concentration. According to the author's research results, the FA concentration which inhibit the Nitrobacteria was below 1.0mg/L,which inhibit the Nitrosomonas was above 10mg/L.

实验研究结果表明：本工艺中，短程硝化反应的最佳pH值在8.0～8.5之间，当pH小于6时，整个硝化反应都会受到抑制，当pH在6～7之间时，随着游离氨浓度的降低，在曝气后期，硝化菌将会占据优势；FA浓度对短程硝化反应的影响是通过对亚硝酸菌和硝酸菌的抑制来实现的，在本研究条件下，游离氨对亚硝酸菌的抑制浓度在10mg/L以上，对硝酸菌的抑制浓度在1.0mg/L以下；温度对短程硝化反应的影响是双重的，既影响微生物的生理活性，又影响FA浓度。
