| 摘 要： | 采用聚砜共混中空纤维超滤膜对油田含油污水进行处理，探讨了不同清洗剂和不同清洗方法对膜通量的恢复效果。试验表明，使用表面活性剂和异戊醇混合溶液为清洗剂，采用负压抽洗和反压冲洗同时进行的方法，可使膜通量恢复率达到９０％以上。

| Abstract: | Oil field polluted water was treated by using polysulphone ultrafiltration memebrane.The effects of different detergents and cleaning methods were studied.The results show that using surfactant and isoamyl alcohol as detergent and simultaneous cleaning of negative pressure and back wash is a better method in which the membrane flux renewal reaches over 90%. |
