摘　　要：超滤技术应用过程中出现膜污染,致使膜通量降低。通过对污染物的成分、膜污染的形成过程,膜材料、原料液、操作条件对膜污染的影响分析,论述了通过原料液预处理、膜材料和膜组件改进、操作条件控制和操作过程控制减轻膜污染,利用物理清洗和化学清洗尽可能恢复膜通量。The membrane is polluted in ultrafiltration separation, and the flux of membrane is reduced. In this paper, the pollutants＇ composition and process of pollution were summarized. Membrane materials, raw materials and operating conditions intluence membrane pollution was analyzed. Raw materials is pretreated, membrane materials and module are improved, operating conditions and process are controlled to lighten membrane pollution. The polluted membrane flux is recovered through physical and chemical cleaning.

关 键 词：超滤 膜污染 污染控制 膜清洗
