印染废水处理技术研究进展

印染废水具有水量大、有机污染物含量高、成份复杂、色度高、碱性大、水质变化大等特点,是难处理的工业废水之一。印染废水的处理方法有物理处理法、化学处理法和生物处理法。文章对印染废水的各种处理方法,从原理、特点及研究进展等方面分别进行了概述,并指出今后印染废水处理技术的优化组合会成为印染废水处理技术的研究重点。

Research Progress on Printing and Dyeing Wastewater Treatment Technology

The printing and dyeing wastewater is characterized by big volumc, high content of organic matters, composed of complex components, heavy color, high alkalinity, great changes in water quality and so on. and is very difficult to be treated. Thc methods in treating printing and dyeing wastcwater include physical treatment, chemical treatment and biological treatment methods. The paper reviewed the principle, characteristic and research development on the printing and dyeing wastewater by each treatment method, and pointed out that the optimization technology oh treating printing and dyeing wastewater will become the research focus on printing and dyeing wastewater treatment.
