| 摘 要： | 通过自制的平板膜对沧州炼油厂热电厂水处理车间反渗透设备的膜污染进行了研究。经电镜扫描与ＥＤＸ能谱分析，测出ＲＯ膜膜而Ｃ、Ｏ、Ｃａ和Ｓｉ等元素的分布情况，确定膜面上的主要污染物是胶体的污染物，微生物污染物以及一定量的ＳｉＯ２颗粒，其中胶体污染物的主要成分是Ｓｉ、Ａｌ、Ｆｅ和一定量的有机物。

| Abstract: | This paper introduces the reasons and causes of RO membrane fouling including looking closely at the foulants with the small self made plate membrane equipment at Heat and Power Plant of Cangzhou Refinery. It also introduces the determination of the appropriate cleaning method for a particular foulant and the choosing of the most appropriate cleaner for membranes and their foulants and chemical cleaning programs. The cleaning process and fast flux level recovery are also both explained. |
