Fenton原位化学氧化法修复有机污染土壤和地下水研究

Organically Polluted Soil and Groundwater Remediation by in situ Fenton Oxidation

Fenton高级氧化技术在废水处理领域已得到深入研究。近年来,该技术在国外有机污染土壤和地下水原位修复中受到越来越多的重视,而在国内相关领域则鲜有报道。虽然国外已有工程试验,但目前对Fenton试剂降解土壤和地下水中有机污染物的研究尚处于基础阶段。本文主要综述了Fenton技术修复有机污染土壤和地下水的发展过程和反应基本机理的研究进展,并针对修复中存在的问题进行了展望。

This paper provides an up-to-date overview of the progress of in situ Fenton oxidation in remediation of soil and groundwater polluted by organic pollutants. As one of the advanced oxidation technologies, Fenton oxidation has been deeply researched in wastewater treatment. Recently, Fenton oxidation attracts more and more attentions in organically polluted soils and groundwater remediation. Fenton reagent has been constantly modified from traditional Fenton reagent in acid reaction to modified Fenton reagent in natural. The rate of degradation has being improved, and the technology is being applied in field scale. The mechanism for the Fenton＇s degradation of the organic pollutants in soil and groundwater is discussed, and the research trends are prospected.
