纳滤复合膜的制备及其在水处理中的研究进展

Research Progress of Nanofiltration and Catalytic Composite Membranes

近年来,工业发展迅速,水污染问题日益严重。纳滤膜在脱盐和废水处理方面得到了广泛应用,但仍然存在着小分子有机污染物去除能力不强的缺陷。将膜的纳滤性能与催化耦合可以克服纳滤膜分离的瓶颈,有效提高水处理能力。本文简要介绍了纳滤膜及其催化纳滤复合膜的制备方法以及应用。

In recent years,industry has developed rapidly and water pollution has become increasingly serious.Nanofiltration membranes have been widely used in desalination and wastewater treatment,but still have the defect that the removal of small molecular organic pollutants is not strong.Coupling the nanofiltration performance of the membrane with catalysis can overcome the separation bottleneck of the nanofiltration membrane and effectively improve the water treatment capacity.This article briefly introduces the preparation methods and applications of nanofiltration membranes and their catalytic nanofiltration composite membranes.
