摘　　要：根据广西横州某垃圾填埋场渗滤液COD浓度高、水质成分复杂,且处理难度较大的特点,设计采用新型两级芬顿氧化工艺对其进行处理。研究对比了两级芬顿与絮凝-芬顿联合处理工艺对该渗滤液中COD的去除效果,通过试验研究了pH值、FeSO_(4)用量、H_(2)O_(2)用量三个因素对处理效果的影响,并确定最佳反应条件。结果表明,两级芬顿氧化工艺对垃圾填埋场渗滤液COD的去除效果更好,在反应条件pH为4.5,FeSO_(4)投加量10 g/L、H_(2)O_(2)投加量0.55 g/L时,COD去除率可达到90%以上。According to the characteristics of a landfill site in Hengzhou,Guangxi,such as high COD concentration of leachate,complex water quality components,and greater difficulty in treatment,a new two-stage Fenton oxidation process was designed to treat it.The removal effects of COD from the leachate by two-stage Fenton and flocculation Fenton combined treatment processes were studied and compared.The effects of pH value,FeSO_(4)dosage,and H_(2)O_(2)dosage on the treatment effect were investigated through experiments,and the optimal reaction conditions were determined.The results show that the two-stage Fenton oxidation process has a better removal effect on COD from landfill leachate.When the reaction condition pH is 4.5,the dosage of FeSO_(4)is 10 g/L,and the dosage of H_(2)O_(2)is 0.55 g/L,the COD removal rate can reach over 90%.
