Application of Advanced Oxidation Processes In the Treatment of Landfill Leachate

Gui Xinan,Yang Haizhen(Environmental Science & Engineering School,Tongji University,Shanghai 200092,China)  
Landfill leachate has very peculiar characters,proved to be toxic and recalcitrant.It is very difficult to make Landfill Leachate degraded only by biological treatment.The reaction mechanism and application in treating landfill leachate of advanced oxidation processes(AOP),such as photocatalytic oxidation,catalytic wet air oxidation,Fenton oxidation,electrochemical oxidation and catalytic oxidation,chemical oxidation,plasma technique and ultrasonic technology,are introduced.Rapid reaction,no secondary pollution,strong adaptability to Landfill Leachate and complete degradation of organic pollutant can be made by AOPs,but more extensive applications for AOPs are restricted by the cost and volume of landfill leachate.Finally the main points of research in the future are also discussed,which will focus on combination of advanced oxidation processes,or combination of advanced oxidation process and biological treatment.
