印染废水处理技术研究进展

印染废水水量大、浓度高、色度深、毒性强、pH波动大,是难处理的工业废水之一。它的大量排放严重污染环境,破坏生态平衡,因此必须对印染废水进行有效处理。文章首先简单介绍了目前常用印染废水处理技术的基本原理和处理效果,总结了各种方法的优缺点,同时特别对生化法、电化学氧化法的现状与进展进行了详细的介绍和评述。

Advanced of the Researches on Printing and Dyeing Wastewater Treatment Techniques

Printing and dyeing wastewater’s quantity is large,the concentration is high,and chromaticity is dark.Its toxicity is strong and pH changes greatly.It is a kind of industrial wastewater which is hard to be treated.Its large number of emissions seriously polluted environmental,destructed ecological balance.Therefore,it is necessary for effective treatment of printing and dyeing wastewater.In this paper,the fundamental principle and treatment effect of various the current printing and dyeing wastewater treatment technologies are described simply in the first place.The advantages and disadvantages of each method is summed up.Meanwhile,the status and progress in biochemical technology and electrochemical oxidation were introduced and reviewed in detail.
