摘　　要：通过分析反渗透膜清洗药剂在清洗前后成分的变化,比较了清洗药剂对铁及相关污染物的去除效果.通过反渗透膜元件清洗前后产水量、脱盐率、膜压降的变化,确定了针对铁污染膜元件的最佳清洗药剂.This paper firstly compares with the removing effects of various cleaning agents on iron and other relevant pollutants on RO membrane elements by analyzing their componential changes before and after the cleaning. And then it determines the best cleaning agent for the iron-polluted membrane elements by analyzing the changes of all the tested agents in water production, desalination and membrane pressure drop.
