高级氧化技术在垃圾渗滤液处理中的研究进展—垃圾渗滤液的进一步处理

Research Progress of Advanced Oxidation Processes in the Treatment of Landfill Leachate

摘要: 近年来，高级氧化技术在处理垃圾渗滤液方面有着突出的优势，如反应速度快、降解有机物彻底、无二次污染、水质适用范围广等，可以明显地提高垃圾渗滤液的可生化性，将难降解的有机物分解，因此受到大家的广泛关注。本文详细总结了近年来国内外采用Fenton法、臭氧氧化法、电催化氧化法、超临界水氧化法、湿式氧化法等高级氧化技术处理垃圾渗滤液的研究进展，并从反应机理、处理成本、处理效果、工程应用可行性等方面对多种高级氧化技术进行比较，希望为高级氧化技术在垃圾渗滤液处理中的应用提供参照。

Abstract: Advanced Oxidation Processes (AOPs) have attracted widely attention in recent years for their unique advantages in treating landfill leachate, such as reacting rapidly, degrading organic mat-ters completely without secondary pollution, improving the biodegradability of landfill leachate greatly even breaking down the refractory organics and being suitable for a wide range of water quality. In this paper, we summarize the recent research progress of AOPs used in treating landfill leachate at home and abroad, including Fenton, ozone oxidation, electro-catalytic oxidation, supercritical water oxidation, wet air oxidation, etc. Besides, for providing a reference for the application of AOPs in landfill leachate treatment project, the comparison was made among these AOPs on the aspects of reaction mechanism, treatment costs, treatment results, engineering application feasibility and so on.
