印染废水处理技术的研究现状与进展摘要：印染废水是指加工棉、麻、化学纤维及其混纺产品为主的印染厂排出的废水，因其通常有很大排放量，成为污染我国水环境的主要因素之一。
本文简述了印染废水的来源、特点及特征污染物，介绍了印染废水的处理工艺技术，并列举了当前国内常用处理工艺技术的特点。
印染废水处理工程，对保护我国人民健康和生态环境以及使我国经济实现可持续发展均有重大的意义。
关键词：印染废水；废水处理技术；纺织工业A review of printing and dyeing wastewater treatment technologyABSTRACT:Printing and dyeing wastewater refers to the wastewater discharged from the printing and dyeing plant which mainly processes cotton, hemp, chemical fiber and their blended products. It is one of the main factors that pollute the water environment of our country because of its large discharge. This paper briefly describes the source, characteristics and characteristic pollutants of printing and dyeing wastewater, introduces the treatment technology of printing and dyeing wastewater, and enumerates the characteristics of current domestic common treatment technology. The treatment of printing and dyeing wastewater is of great significance to protect the peoples health and ecological environment and to realize the sustainable development of Chinas economy.KEYWORDS: printing and dyeing wastewater；wastewater treatment technology；textile industry导言我国是纺织大国，纺织产业对我国国计民生发挥着巨大作用。
同时，纺织产业又是重污染行业，尤其是印染废水的排放量已跃居全国工业企业废水排放量的前4位[1]。
纺织工业废水年排放量高达约20.0亿t，在全国41个工业行业中位居第3位。
其中，印染作为提升纺织品附加价值的关键环节，废水及其污染物排放总量占全行业的70%~80%。
同时，约93%的印染产能集中在山东、江苏、浙江、福建和广东这5个沿海省份，废水的排放对近岸水环境造成了潜在的生态风险[2]。
笔者在分析印染废水特点的基础上，介绍了当前印染废水的主要治理技术及存在的相应问题。
