膜集成技术在纺织废水处理中的应用进展

Abstract

我国是纺织大国，纺织废水一直存在着排放量大、污染严重等问题，因此纺织废水的处理受到广泛关注。本文总结了纺织废水的来源和水质特点；简述了国内外处理纺织废水的主要传统工艺路线，但是传统工艺路线不足以解决纺织废水中存在的高色、高毒等问题；重点论述了以膜分离为主的膜集成技术在纺织废水中的应用，比较了超滤、纳滤以及反渗透技术在纺织废水中的工艺路线；为纺织废水的处理，特别是高色、高毒污染物的去除，提供了理论依据和技术参考。 China is a textile power, textile wastewater has been a large amount of emissions, serious pollution and other issues, so the treatment of textile wastewater has been widespread concern. This paper summarizes the source and characteristics of textile wastewater; The main traditional process route of textile wastewater treatment at home and abroad is briefly described. However, the traditional process route is not enough to solve the problems of high color and high toxicity in tex-tile wastewater. The application of ultrafiltration, nanofiltration and reverse osmosis technology in textile wastewater was compared with the application of membrane integration technology in textile wastewater. It provides theoretical basis and technical reference for the treatment of textile wastewater, especially the removal of high color and high toxic pollutants.
