生物接触氧化工艺在印染废水治理中的应用

The Use of Bio-contact Oxidation Technology in Treatment of Printing and Dyeing Wastewater

通过对某一针织印染厂生产废水处理工艺存在的问题进行研究和分析，对其废水处理工艺进行了改进，针对废水水质特点，采用“缺氧酸化＋生物接触氧化”相结合的工艺路线进行治理。运行结果表明，经该工艺处理后，废水中的COD、BOD，等指标均能达标排放，有利于企业的可持续发展。

Through the research and analysis of wastewater treatment problems of a knitting and dyeing factory, considering the feature of wastewater quality, the anthor offers improvement measures which combines Hypoxic acidification and Bio-contact Oxidation. The resulut shows that indexes like COD. BOD5 can meet discharging standards, and this helps sustainable development of enterprises.
