超滤膜的污染控制研究进展

Research Progress in Fouling Control of Ultrafiltration Membrane

以超滤技术为核心的组合工艺作为微污染水源水处理的一项新技术,引起了人们越来越多的关注,成为给水处理领域研究的热点,也为农村和小城镇水厂提供了很好的处理工艺,但膜污染一直是超滤技术在实际工程中推广应用所面临的一大障碍。总结了近年来超滤膜污染控制方面的新进展,包括膜污染的成因及机理、膜污染防治以及膜清洗等,并提出了今后超滤膜污染研究的重点和方向。

As a new purification technology of micro-polluted raw water, the ultrafitration combined with other conventional treatment technologies attracts more and more widespread attention and becomes a hot issue in drinking water treatment, and also provides a choice for rural and small town water plants. However, the membrane fouling in uhrafiltration is a great obstacle problem which restricts its widespread popularization and application in actual projects. The new progresses in ultrafiltration membrane fouling control in recent years are summed up, which include the mechanisms and various factors that affect membrane fouling in uhrafihration, the technologies for membrane fouling prevention and control, the membrane cleaning methods and so on. The future research emphases and directions of membrane fouling in ultrafiltration are put forward.
