摘要
以去除垃圾渗滤液生化出水中的CODCr和腐殖酸相对含量(UV254)为研究内容,对Fenton技术应用及其工艺技术条件优化进行了实验室条件下的模拟试验研究。结果表明,1)快速Fenton工艺优化条件为:初始p H值为4.0,H2O2投加量为1500 mg/L,Fe2+投加量为500 mg/L,静置时间120 min,CODCr由处理前的652 mg/L降到处理后的300.06 mg/L,去除率达53.99%;2)光催化Fenton氧化优化条件为:初始p H值为4.0,H2O2投加量为1000 mg/L,紫外灯功率为72 W,反应时间为120 min,CODCr由处理前的300.06 mg/L降到处理后的86.4mg/L,去除率达71.18%。说明,该工艺对处理垃圾渗滤液生化出水是有效的,可进行大规模的中试研究。
The removal ratio of C0DCr and humic acid relative content （ UV254）, via the Fenton process, were investigated in landfill leachate biochemical effluent. Laboratory experiments were conducted to determine the optimal conditions of Fenton process. The results indicated that the optimal parameters in second kill Fenton process were as follows： the init ial pH 4. 0, ^0 .dosage 1500 mg/L,Fe2＋ dosage 500 mg/L and reaction time 120 min. Under these conditions, C0DCr was reduced from 652 mg/L to 300. 06 mg/L and the removal ratio was 53. 98%. The optimal reaction conditions in photo catalytic Fenton process were as follows： the in it ia l pH 4. 0, H202 dosage 1000 mg/L , UV lamp power 72 W and reaction time 120 min. Under which, C0DCr was reduced from 300. 06 mg/L to 86. 4 mg/L and the removal ratio was 71. 1 8 % . According to the results, Fenton oxidation process was effective for treatment of land fill leachate, and could be carried out on a large scale.
