活性炭-Fenton预处理垃圾渗滤液的研究

Research on Treatment of Landfill Leachate by Activated Carbon-Fenton Process

以颗粒活性炭为催化剂,建立活性炭-Fenton催化氧化体系,对垃圾渗滤液进行有效处理,分别考察了反应时间、pH、活性炭用量、硫酸亚铁用量和H2O2用量对废水处理效果的影响,结果表明:在反应时间为30 min、pH为3、活性炭用量20 g/L、硫酸亚铁用量0.02 mol/L和H2O2用量2 mL/L的条件下,可使废水的COD从3 000 mg/L降至1 552.2 mg/L,COD去除率达到48.26%.

Landfill leachate was treated by catalystic oxidation process, in which granular activated carbon （GAC） was used as catalyst. The effects of reaction time, pH, dosage of activated carbon, dosage of FeSO4 and H2O2 on disposing rate were studied. The results showed that COD in the waste water was reduced from 3000 mg/L to 1552.2 mg/L under the optimal conditions of reaction time 30 min, pH3, GAC 20 g/L, FeSO4 0.02 mol/L,and H2O2 2 mL/L. the removal rate of COD was 48.26%.
