摘　　要：针对当前垃圾渗滤液普遍存在的有污染物浓度高、有机污染物含量多且难降解问题,采用铁碳微电解法对该废水进行处理,以垃圾渗滤液中COD的去除率为指标,考察初始pH值、反应时间和铁碳投加量3个主要因素对废水中有机污染物去除效果的影响。结果表明:3个因素对实验结果的影响程度比较为:初始pH值>反应时间>铁碳投加量。当初始pH=3,反应时间120 min,铁碳投加量66 g/L时,垃圾渗滤液中COD的去除率可以达到53.5%。因此,铁碳微电解法处理垃圾渗滤液具有良好的效果,可以为该工艺在垃圾渗滤液治理领域中的应用提供一定的参考。In view of the high concentration of pollutants,the content of organic pollutants and the difficulty of degradation in landfill leachate,the iron-carbon micro-electrolysis method was used to treat the wastewater,and the removal rate of COD in landfill leachate was used to investigate the effects of three main factors,namely initial pH value,reaction time and iron-carbon dosage,and the removal effect of organic pollutants in wastewater.The results showed that the influence of the three factors on the experimental results was in the order of initial pH value>reaction time>iron and carbon dosage.When the initial pH=3,the reaction time was 120min,and the iron-carbon dosage was 66g/L;the removal rate of COD in landfill leachate could reach 53.5%.Therefore,iron-carbon micro-electrolysis has a good effect in the treatment of landfill leachate.This study can provide a certain reference for the application of this process in the field of landfill leachate treatment.
