摘要
采用由H_2O_2和FeSO_4配制成的Fenton试剂,对垃圾渗滤液进行了后处理;考察了渗滤液的pH值,H_2O_2和FeSO_4的投加量及反应时间对COD和色度的去除效果。试验确定最佳条件为:pH值3.0,FeSO_41500mg/L,H_2O_220mL/L,反应时间60min,此时COD与色度去除率分别为79.7%和95.2%。
The Fenton reagent made from H2O2 and FeSO4 was adopted to process the landfill leachate. The effects of pH,H2O2 dosage, FeSO4 dosage and the reaction time on the removal of COD and chromaticity were investigated. The optimum conditions determined by the test were pH of 3.0, FeSO4 of 1500 mg/L, H2O2 of 20 mL/L and the reaction time of 60 min,with the removal rate of COD 79.7% and chromaticity 95.2%.
