摘要

某超滤系统运行中出现产水量显著下降

对超滤膜丝进行电镜和能谱分析发现

其主要是由铁、锰胶体以及无机钙垢造成超滤膜的污堵所致

对此

采用盐酸、硫酸、柠檬酸、草酸溶液对膜丝进行静态浸泡试验。结果表明

草酸对铁锰胶体的清洗效果最好

实际清洗后

跨膜压差和产水量基本恢复至初始状态。

Abstract

The water yield dropped significantly during operation of an ultrafiltration system.The electron microscope analysis and energy spectrum analysis indicated the iron-manganese colloid and calcium scale were the main contaminants.Thus

the hydrochloric acid

sulfuric acid

oxalic acid and citric acid were used as the cleaning solvent to conduct static immersion test.The results showed that citric acid had the best cleaning effect on iron-manganese colloid.After cleaning

the transmembrane pressure difference and water yield recovered to the initial values.
