| 摘 要： | 采用絮凝沉淀-Fenton试剂氧化法处理含高浓度硫酸盐的洗涤剂生产废水（简称废水），考察了各种因素对COD去除率的影响。实验结果表明：根据实际废水的水质情况，选用聚合氯化铝（PAC）为絮凝剂，PAC最佳加入量为0．3g／L，经絮凝处理后COD去除率为42．3％；Fenton试剂氧化的最佳操作条件为：n（H2O2）：n（Fe^2＋）=0．5、H2O2加入量为7mmol／L、反应时间为2h，不调节废水初始pH，经Fenton试剂氧化处理后COD去除率为70％以上。经絮凝沉淀-Fenton试剂氧化法处理后，废水COD由1950mg／L降至240mg／L，总的COD去除率为87．7％，废水处理效果良好。

| Abstract: | High concentration sulfate wastewater in detergent production was treated by flocculation- Fenton reagent oxidation process and the factors affecting the removal rate of COD were studied. According to the wastewater quality,PAC was used as flocculant with the optimum dosage of 0.3 g/L,the COD removal rate is 42.3% after flocculation.Under the optimum conditions of n(H_2O_2)/ n(Fe~(2+))0.5,H202 dosage 7 mmol/L,reaction time 2 h and without pH adjustment,the COD removal rate is above 70% after Fenton reagent ... |
