微电解-水解酸化/接触氧化工艺处理染化废水的研究

摘要：染料化工废水有高浓度、高色度、高盐度和含有大量难降解有机物等特点，而且成分复杂、水质变化比较大，难以直接进行生物处理。本文采用微电解-水解酸化/接触氧化工艺对染料化工废水进行了处理研究，实验结果表明：经过微电解处理后废水的悬浮性有机污染物得到很好的去除，去除率达到73%-81%；且去除效果与pH有关，在pH值1.6-3.0范围内，pH值越低，效果越好；经微电解和水解酸化处理后，废水的可生化性得到大幅度的提高，平均从0.23提高到0.45。

Research on the Treatment of Dyestuff Wastewater by the Process of Microelectrolysis-Hydrolytic Acidification/Contact Oxidation

Abstract：Dyestuff wastewater has the features of high concentration, deep color, high salinity, containing a lot of refractory organic, and it is complicated, has large changes in water quality and hard to treat with biochemical methods directly. In this paper, the process of microelectrolysis-hydrolytic acidification/ contact oxidation was used in the research dyestuff wastewater treatment. It can be found in the result that after the treatment of microelectrolysis, the suspended organic pollutants was well removed, the removal rate reached 82%-96%; the remove effect had a pH relationship, between the pH value of 1.6-3.0, pH value at the end of the more effective the better the micro-electrolysis and acid hydrolysis processing; after the treatment of microelectrolysis and hydrolytic acidification, the wastewater was more biological, the BOD5/ CODCr was increased averagely from 0.23 to 0.45.
