采用FeCl3混凝联合H2O2氧化作用处理垃圾渗滤液，考察混凝-氧化法对垃圾渗滤液的处理效果。比较了先混凝后氧化(方法一)与先氧化后混凝(方法二)的处理效果，结果表明，方法一优于方法二，主要是因为方法二中的混凝效果低于方法一。无论是方法一还是方法二，加入氧化剂均不能提高对浊度的去除效果。在原水CODCr的质量浓度为4100 mg/L、浊度为147 NTU、 UV254为20、色度为2125度的条件下，采用方法一， H2O2能大大提高垃圾渗滤液中有机物的去除率，在H2O2的投加量为5~80 mL/L范围内， CODCr、 UV254、色度的去除率均呈增加趋势，最高去除率分别达60.84%、62.66%、73.79%。

Using combined FeCl3-H2O2 to treat landfill leachate, the effect of coagulation-oxidation process on its treatment was investigated. The effects of landfill leachate treatment by coagulation before oxidation (method 1) and by oxidation before coagulation (method 2) were compared, the results showed that, the treat-ment effect by method 1 was superior to that by method 2, that because the former had a better coagulation per-formance. However, adding oxidant had little influence on turbidity removal neither in method 1 nor in method 2. Under the condition that the mass concentration of CODCr was 4 100 mg/L, the turbidity was 147 NTU, the value of UV254 was 20, the chroma was 2 125 degree, using method 1 with H2O2 added could greatly improve the re-moval rate of organic matters in the landfill leachate. When the dosage of H2O2 was 5-80 mL/L, the removal rates of CODCr, UV254 and chroma all showed increasing tendency, and the maximal removal rates reached 60.84%, 62.66%and 73.79%respectively.
