摘　　要：反渗透膜的污染是反渗透系统应用中最大的问题之一,及时的化学清洗可有效地恢复反渗透膜的性能、延长其使用寿命。对反渗透膜的污染及其化学清洗方法进行了综述,主要内容包括反渗透膜污染物的种类,污染物形成的原因,以及清洗时机的选取,清洗药品的选择,影响清洗效果的主要因素、清洗系统的构成,化学清洗的方法和清洗效果的评价指标。Fouling is one of the most important problems associated with the application of membrane. The performance of membrane can be restored by immediate chemical cleaning. In this paper, the research and application on fouling and chemical cleaning for Reverse Osmosis are reviewed, and the categories and forming mechanism of fouling, the choosing of cleaning time, the selecting of cleaning agents, the main factors affecting the cleaning efficiency, the formation of cleaning system, the cleaning methods and the parameters demonstrating the cleaning efficiency were introduced.
