印染工业废水处理的研究现状

Research Status of Dyeing Wastewater Treatment

印染工业废水组分复杂 ,常含有多种染料 ,色度深 ,毒性强 ,难降解 ,pH值波动大 ,而且浓度高 ,水量大。本文旨在介绍国内外印染废水处理方法发展现状 ,详细介绍了物理法 ,化学法 ,物理化学法和生物法等方法 ,列出各种处理方法的适用条件及处理效果 ,并总结出各自的优缺点。

Wastewater of dyeing industry has complicated constituents, and usually contains many kinds of dyes. It has deep tinct and strong toxicity, and it is difficult to decompose it. Its pH value fluctuates widely, and it has high concentration and large water quantity.The development status of the dyeing wastewater treatment inside and outside China is introduced, and the physics method, chemical method, physical chemistry method and biological method are stated in detail. The applicable conditions and treating effect of the four methods are listed and the advantages and disadvantages are concluded.
