超滤预处理技术在膜污染防止中的应用

作为一种具有发展前景的饮用水净化工艺,超滤膜技术日益得到广泛应用。但是膜污染一直是困扰其发展的主要因素。将传统的处理技术与超滤膜相结合,通过预处理的方式在提高水质的同时可以防止膜污染的生成。本文主要讨论了混凝、吸附、预氧化和其他预处理方法及其组合方法在水处理中应用和对膜污染的抑制作用。未来研究方向应在深入讨论膜污染机理的基础上,针对不同情况进行分析。

Ultrafiltration pretreatment technology in the application of membrane pollution prevention

As a promising water treatment process,ultrafiltration has gained wide application while the fouling of membrane has always been the problem.The pretreatment of combination of traditional treatment and UF is an effective way to reduce fouling.The paper mainly discuss the pretreatments of UF to avoid membrane fouling,such as coagulation,adsorption,pre-oxiation and other ways.In order to make further experiments,efforts should be made to deeply study the mechanisms of membrane fouling according to certain situations.
