微電解-水解酸化/接觸氧化工藝處理染化廢水的研究

摘要：染料化工廢水有高濃度、高色度、高鹽度和含有大量難降解有機物等特點，而且成分復雜、水質(zhì)變化比較大，難以直接進行生物處理。本文采用微電解-水解酸化/接觸氧化工藝對染料化工廢水進行了處理研究，實驗結果表明：經(jīng)過微電解處理后廢水的懸浮性有機污染物得到很好的去除，去除率達到73%-81%；且去除效果與pH有關，在pH值1.6-3.0范圍內(nèi)，pH值越低，效果越好；經(jīng)微電解和水解酸化處理后，廢水的可生化性得到大幅度的提高，平均從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.
