摘　　要：针对初始水质为pH 8.9、硫化物46.3 mg/L、COD 5 602.92 mg/L、Cr3+57.2 mg/L、色度为1 300倍、浊度2 300 NTU的制革综合废水,使用高铁酸钾/聚合硫酸铁联用和单独使用高铁酸钾进行处理,结果发现,使用15 mg/L高铁酸钾和50 mg/L聚合硫酸铁联用处理制革综合废水具有更好的效果,其中,COD去除率为96.12%、硫化物去除率94.25%、Cr3+去除率95.15%、浊度去除率为99.15%、色度去除率为92.36%。The integrated tanning wastewater, whose initial water quality conditions are as follows ： pH is 8.9, sulfide 46.3 mg/L,COD 5 602.92 mg/L,Cr3＋ 57.2 mg/L,turbidity 2 300 NTU and chroma 1 300,has been treated with potassium ferrate/polyferric sulfate simultaneously and individually. As a result,it is found that when 15 mg/L of potassium ferrate and 50 mg/L of polyferric sulfate are used simultaneously, its efficacy is better. Its COD removing rate is 96.12% ,sulfide removing rate 94.25% ,Cr3＋ removing rate 95.15% ,turbidity removing rate 99.15% and chroma removing rate 92.36%.
