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。

Secondly, the silver based catalysts modified by phosphorus, zirconium, zinc, potassium and so on using molecular sieve as carrier, which were produced by ion-exchange method, had also good catalytic performance for 1,2-propane glycol oxidation to methylglyoxal. The conversion of 1,2-propane glycol and the selectivity of methylglyoxal were both high, and the impurity such as formaldehyde and acetaldehyde in the product is little. At the condition of the temperature 300 ℃, the molar ratio of oxygen to 1,2-propane glycol 1.7:1, the space velocity 6000h~(-1), and the concentration of 1,2-propane glycol 70wt%, the conversion of 1,2-propane glycol is 90% and the selectivity of methylglyoxal is 45% on the Ag-P catalyst.
