摘要
采用常用的膜的清洗方法及清洗剂 ,清洗被鞣质、果胶污染后的中空纤维膜 .结果表明 ,用几种清洗剂依次交替清洗 ,能使膜通量有较好的恢复 ,且实验重复性好 .
The common cleaning process and cleaning agents were used to clean the hollow fiber ultrafiltration membranes fouled by tannic acid and pectin,which were regarded as the main pollutants in the decocta of traditional Chinese herbs.The results showed that the flus was recovered well after the cleaning using several chemical agents alternately combined with physical methods,and the good repeatability was observed.
