有机物污染土壤修复方法介绍

摘要

土壤中有机污染物种类繁多，强烈的疏水性，与土壤结合紧密不易被微生物降解，在食物链中易堆积且具有潜在的致癌风险，使得土壤中有机物污染的修复成为大家关心的热点。文章主要介绍溶剂萃取、化学氧化、电动力修复、生物修复、植物修复法、热解法在修复土壤中的有机污染物方法。%Hydrophobic organic compound (HOCs) are carcinogenic micropollutants which are resistant to environmental degradation due to their highly hydrophobic nature.Concerns over their adverse health effects have resulted in extensive studies on the remediation of soils contaminated with HOCs.This paper aim to provide a review of the remediation technologies for HOCs con-taminated soils.The technologies discussed here include solvent extraction,chemical oxidation, electrokinetic remediation,bioreme-diation,phytoremediation,thermal treatment.
