| 摘 要： | 采用PAC(聚合氯化铝)与PFS(聚合硫酸铁)混凝剂处理污水，并进行了对比实验。结果表明。在污水COD浓度为920mg／L，PFS折算为Fe2O3的投加量为300mg／L，pH为9．0时，出水COD为406mg／L，COD去除率为55．8％，而PAC折算为Al2O3的投加量为120mg／L时，出水COD为369．8mg／L，COD去除率为59．8％。PAC较PFS对COD的去除率高约4％。

| Abstract: | Experimental research on PAC and PFS is carried, and the result shows that, under COD of waste water being 920 mg/L, the COD of effluent is 406.6 mg/L.The removal rate of COD is 55.8%,when the optimum dosage of Fe_2O_3 and pH of water are 300 mg/L and 9.0 respectively. For PAC, the optimum dosage of Al_2O_3 and pH are 120.0 mg/L and 9.0 respectively, while the COD of effluent is 309.8 mg/L, and the removal rate of COD is 59.8%, which is 4% higher than PFS. At the same time, the price of PAC in treating wastewater is less about 0\^10 Yuan per-ton than PFS. |
