摘　　要：采用陶瓷膜处理港口含油废水。试验探讨了几个参数对膜分离过程的影响,着重考察了料液pH值、操作压差、膜面流速等条件对膜通量和截留率的影响,由此确定了最佳操作条件。同时对采用化学清洗剂对膜污染的清洗效果也一并进行了讨论。Using ceramic membrane to treat oily wastewater from coastal port, the influence of some parameters in the experiment on the membrane separation process is discussed. Especially, the influence like the liquid pH value, operation pressure difference and the velocity of membrane surface flow on the membrane flux and retention rate is examined. The optimal operation condition was determined therefore. Meanwhile, the cleaning effect by using chemical detergents on the membrane fouling was discussed.
