摘　　要：综述了当前使用超滤工艺处理饮用水的现状及其优势特点,介绍了超滤工艺对不同污染物的去除效果,并总结了造成超滤过程中膜污染的污染物种类及膜污染类型;分析了目前超滤工艺中膜污染出现的主要原因,重点总结了当前减缓膜污染所采取的措施,包括膜前预处理、对膜材料的控制及改性操作、优化膜处理工艺以及对污染的膜进行清洗等。同时对当前饮用水超滤技术的局限性和前景进行分析,为超滤技术在今后饮用水处理领域的主要研究方向提供了思路。This paper introduced the status and advantages of the ultrafiltration process and its effects on the removal of pollutants,and the types of pollutants which caused the membrane fouling and types of membrane fouling were also summarized. The main reasons for the membrane fouling in the current ultrafiltration process were analyzed,and the measures which could be used to reduce membrane fouling were also summarized,including pretreatment method,optimization of membrane materials and operation process,and cleaning of contaminated membranes. At the same time,the limitations and prospects of the ultrafiltration technology for current drinking water treatment were analyzed,which could provid ideas for the main research directions of ultrafiltration in the field of drinking water treatment in the future.
