用Fenton试剂处理福建某铜锌选矿废水周吉奎1,2,喻连香1,2,胡洁1,21. 广州有色金属研究院摘 要:福建某铜锌选矿厂经过混凝沉降初级处理后的生产废水清澈透明,p H为中性,固体悬浮物和重金属离子含量达到国家排放标准,但由于含大量丁黄药等有机质而使COD值高达377.2 mg/L,既不能直接排放也不能直接回用.为将该废水的COD值降到100 mg/L以下以满足排放或回用的要求,采用Fenton试剂对其进行了去除COD的试验研究.试验结果表明:在初始p H为3,H2O2溶液(浓度30%)用量为2 m L/L,Fe SO4·7H2O用量为0.5 g/L的条件下搅拌反应60 min,废水的COD值可降低至25.2 mg/L,相应的COD去除率高达93.32%,从而显示出Fenton试剂降解有色金属矿......
