膜分离技术用于印染废水处理及回用的研究进展

摘要

Wastewater quantity of printing and dyeing industry is large, water quality is complex, and the wastewater has big influence on environment, it's the substantial part of industrial wastewater treatment. In recent years, more and more printing and dyeing wastewater has been treated by membrane separation technology with the more and more widely application of membrane technology in wastewater treatment industry, the recycled water can satisfy reuse requirement, and it effectively remission water consumption and water resource has been saved. Application progresses of different membrane separation techniques in printing and dyeing wastewater treatment were reviewed, the advantages and problems for membrane separation technology in printing and dyeing wastewater treatment were indicated.%印染行业的废水量大、水质复杂、对环境影响大，是工业污水处理的重要部分。近年来，随着污水处理行业膜技术的应用越来越广泛，印染废水采用膜分离技术也逐渐增多，其出水能满足回用要求，有效地缓解了用水量，节约了水资源。综述了不同膜分离技术在印染废水中的应用进展，指出了膜分离技术处理印染废水的优势及其存在的问题。
