摘　　要：以混凝-铁炭微电解-芬顿高级氧化工艺对垃圾渗滤液进行深度处理。探究了混凝剂投加量、微电解时间及H_2O_2投加量等因素对COD去除效果的影响。在PAC投加量为1 400 mg/L,PAM投加量为800 mg/L,铁炭微电解时间为3 h,H_2O_2的投加量为4 mL/L的条件下,垃圾渗滤液的COD整体去除率在84.7%左右,溶液的色度明显减小,有利于后续的生化处理。The advanced treatment of landfill leachate was carried out by coagulation, Fe/C micro electrolysis and Fenton advanced oxidation process. The effect of coagulant dosage, micro electrolysis time and H2 O2 dosage on the COD removal efficiency was investigated. The results showed that, when the dosage of PAC was 1 400 mg/L, the dosage of PAM was 800 mg/L, the time of Fe/C micro electrolysis was 3 h, and the dosage of H2 O2 was 4 mL/L, the leachate COD removal efficiency was about 84.7%, the solution chroma decreased significantly, which was conducive to follow-up biochemical treatment.
