摘　　要：超滤是废水净化的最佳选择之一,然而不可避免的膜污染问题制约了超滤技术的进一步发展。通过阐述超滤膜污染过程和影响因素,精准认知污染类型和污染机制,不断优化膜运行条件,适当地改变操作参数,选择合适的清洗方式和清洗剂,以获得较高的污染物去除率和膜渗透率,降低超滤技术成本。Ultrafiltration is one of the best choices for wastewater purification.However,the inevitable membrane fouling problem has restricted the further development of ultrafiltration technology.It was indicated that,by expounding the ultrafiltration membrane pollution process and the influencing factors,accurately understanding the type of pollution and the pollution mechanism,continuously optimizing the membrane operating conditions,appropriately changing the operating parameters,selecting proper cleaning method and cleaning agent,higher pollutant removal rate and membrane permeability could be obtained with lower ultrafiltration technology cost.

关 键 词：超滤 膜污染 操作参数 物理清洗 化学清洗
