微电解-催化氧化-SBR法处理染料废水试验研究

Testing Study on Electrolysis-Catalytic Oxidation-SBR Process for Treating Dyeing Wastewater

对微电解 -催化氧化 -SBR法处理染料废水进行了实验研究。通过探讨体系的最佳条件 ,得出结果。用微电解 -催化氧化 -SBR法处理染料水 ,其CODCr和色度的去除率都达到 90 %以上 ,排放水的CODCr值小于 2 0 0mg/L ,色度小于 10 0 ,达到国家二级排放标准 ( pH6～ 9,色度为 10 0 ,CODCr为 2 0 0 )。

Research on electrolysis-catalytic oxidation-SBR process to treat dyeing wastewater were conducted.Treatment effectiveness under optimal conditions were analyzed and results were discussed.With the electrolysis-catalytic oxidation-SBR process,the study showed approximately 90% removal rate for both chroma and COD Cr .After the treatment,with less than 200mg/L in COD Cr and less than 100 in chroma,the effluent reached national second discharge level.
