摘　　要：探讨了垃圾渗滤液的曝气铁碳内电解处理工艺。结果表明,曝气铁碳内电解工艺能显著提高垃圾渗滤液CODCr和色度的去除率,CODCr的平均去除率达到50%～80%,优于传统非曝气的工艺,色度的去除由于絮凝程度的提高也得到了增强。垃圾渗滤液经过曝气铁碳内电解处理后,pH值和氨氮变化均不大。Aerate Iron-Carbon Internal Electrolysis （AIC1E） is used to treat landfill leachate under aeration conditions. Results show that, the removal rate of CODCr reaches 50%-80% under AICIE, higher than that under Iron-Carbon Internal Electrolysis （ICIE） Condition （30%-60%）. Organic molecule＇s reduction plays an important role in the course of CODCr removal under anaerobic condition, while, the flocculation effect of iron ion is the most important factor for the color removal under aeration condition. The variation of pH and NH3-N under AICIE is within 10%.
