Research Process on Treatment of Organic Pollutants in Landfill Leachate by the Fenton Oxidation Technology

传统渗滤液处理工艺对渗滤液中新兴污染物去除效率较低,处理后外排的渗滤液会给生态环境带来较大的风险。综述了渗滤液中新兴污染物的分布特征,阐释了Fenton工艺对有机污染物的去除原理与效率。综述了类Fenton和耦合Fenton工艺的应用与发展及对有机污染物降解效率的影响。认为生物电Fenton氧化性较强,无需外加电源,与其他Fenton法相比,具有较好应用前景。

The conventional leachate treatment process has low removal efficiency of the emerging pollutants in leachate,and the leachate discharged after treatment will bring greater risks to the ecological environment.In this paper,the distribution characteristics of common emerging pollutants in leachate were reviewed,and the mechanism of treatments and the removal efficiency of organic pollutants were described.The application and development of Fenton-like and coupled Fenton processes and their effects on the degradation efficiency of organic pollutants were summarized.Compared with other Fenton methods,the bio-electro-Fenton system has a better application prospect because of its strong oxidation property and no external power supply.
