类Fenton法修复氯代有机物土壤污染研究进展

Research Progress on Fenton-like Remediation of Chlorinated Organics Soil Pollution

国内土壤污染形势非常严峻,氯代有机物具有散布范围广,毒害性质强等特点而难以轻易降解。以Fenton法降解氯代有机化合物的原理为基础,总结了利用增溶洗脱和添加表面活性剂,改变反应条件,改善活化自由基等方法得到更为有效的类Fenton处理法,在对其应用于含氯代有机化合物土壤污染修复过程的机理以及相应技术特点进行综述,并对类Fenton法进行总结与展望。

The situation of soil pollution in China is very serious.Chlorinated organics are difficult to be easily degraded due to their wide range of distribution and strong toxic properties.By Fenton method based on the principle of biodegradation of chlorinated organic compounds,the use of solvent elution,adding surface active agent,changing reaction condition,and improving the active free radicals to obtain a more effective Fenton-like treatment method were summarized,for its application in chlorinated organic compounds contaminated soil restoration process and the corresponding technical characteristics were reviewed,the mechanism of and the kind of Fenton method were summarized and prospected.
