中文摘要：

应用自制微孔扩散式接触反应器，考察了H2O2／O3在不同摩尔比下对垃圾填埋场后期渗滤液的氧化处理效果。结果表明，H2O2／O3的摩尔比对处理效果有明显的影响。在试验范围内，确定H2O2／O3的最佳摩尔比为0．2：1，最佳处理时间为90min，经过H2O2／O3处理后，垃圾填埋场后期渗滤液的BOD5／COD可从初始的0．17提高到0．36，改善了废水的可生化性，同时渗滤液的色度、浊度、腐殖酸和SS也有较高的去除率。

英文摘要：

H2O2/O3 was taken to treat the landfill leachate in the later stage at different mol ratio in a microporous transfer contact reactor specially designed. The experimental results showed that the utilization ratio of ozone and the removal of COD and humic acid in leachate was affected by the mol ratio of H2O2 and O3. After 90 min action at mol ratio 0.2： I of H2O2 and O3 ,the value of BOD3/COD of landfill leachate in the later stage was increased from 0. 17 to 0.36, which reflected that the biodegradability of the landfill leachate had been improved markedly. At the same time, H2O2/O3 can effectively remove the chroma, turbidity, humic acid and SS of leachate.
