摘　　要：采用混凝预处理和Fenton深度氧化法联合处理,实验得到了PAC和FeSO4两种混凝剂的最佳投加量,在此基础上,研究了初始pH、FeSO4投加量、H2O2/Fe2+物质的量的比等因素对Fenton反应的影响。实验结果表明,在各自最佳条件下,PAC-Fenton和FeSO4-Fenton对COD的去除率可分别达到91.4%和90.3%,其中,FeSO4-Fenton法在工业应用方面更具优势。Coagulation and Fenton combined methods were used to treat the landfill leachate.The optimum dosage of PAC and FeSO4 was obtained by the experiment.The factors of Fenton reaction such as initial pH,the dosage of FeSO4,the mole ratio of H2O2/Fe2＋ etc were studied by experiments.The results show that under the optimum conditions,PAC-Fenton and FeSO4-Fenton process on COD removal rate can reach 91.4% and 90.3% respectively,in which FeSO4 coagulation-Fenton process is more advantageous in industrial applications.
