| 摘 要： | 采用臭氧氧化法处理经反渗透膜处理后的浓缩垃圾渗滤液，考察了反应时间、臭氧投量、pH和温度对COD，色度以及浓缩液中腐殖酸的去除影响，通过BOD5/COD变化分析了臭氧氧化对浓缩液生化性的提高作用。结果表明：在pH 8.0，温度30℃，臭氧投量5 g/h，反应时间90 min的条件下，浓缩液的COD、色度以及浓缩液中腐殖酸的去除率分别达到67.6%、98.0%和86.1%， BOD5/COD从0.008提升到0.26，生化性有很大提高。

| Abstract: | Concentrated landfill leachate rejected from reverse osmosis was treated using ozone oxidation techonology.The effects of reaction time,dosages of ozone,pH and temperature on removals of COD,color and humic substances were investigated.Moreover,the changes of BOD5/COD were studied to analyze the biodegradability of the leachate.The removal efficiencies of 67.6%,98.0% and 86.1% for COD,color and humic substances were achieved,respectively.The ratio of BOD5 /COD increased from 0.008 to 0.26 demonstrated that the biodegradability of landfill leachate was improved using ozone oxidation technology. |
