Abstract

Abstract:

More and more attention has been paid to harmless treatment of landfill leachate in recent years. In view of the shortage of conventional processing methods and the technical superiority of supercritical water oxidation in the treatment of landfill leachate, the present situation of the research progress in the treatment of landfill leachate by supercritical water oxidation both in China and abroad is introduced. Current research mainly focuses on the treatment efficacy of landfill leachate, and the effects of process control parameters and macroscopic reaction kinetics, etc. Although realizing innocuous treatment of landfill leachate by supercritical water oxidation is feasible, further research are still needed regarding corrosion, blockage, catalyst, reaction mechanisms, nitrogen oxide emissions, and so on.

Key words: landfill leachate, supercritical water oxidation, kinetics, catalysts

摘要：

目前垃圾渗滤液的处理越来越引人关注，鉴于常规处理方法在渗滤液处理方面的不足及超临界水氧化的技术优势，介绍了国内外垃圾渗滤液超临界水氧化处理的研究现状。目前的研究方向主要集中在渗滤液的处理效果、过程控制参数的影响、宏观反应动力学等方面，虽然超临界水氧化技术实现垃圾渗滤液的无害化处理是可行的，但是在腐蚀、管道堵塞、催化剂、反应机理、氮氧化物排放等问题的研究不足，仍需深入研究。
