摘要
重金属–有机物复合污染已是土壤污染的一种普遍形式,其环境危害和治理难度远大于单一污染土壤,因此,重金属–有机物复合污染土壤修复治理是我国环保领域亟需解决的现实难题。基于此,本文首先介绍了重金属与有机污染物在土壤中的复合污染现状;其次,分析了土壤中重金属与有机污染物的交互作用及其环境效应;然后,从物化修复、生物修复和联合修复这3方面综述了不同技术手段对重金属–有机物复合污染土壤修复的研究进展;最后,提出了重金属–有机物复合污染土壤修复研究的发展方向。
Heavy metal and organic pollutant co-contamination has become a primary form of soil pollution in China.The environmental harm and remediation difficulty of heavy metal-organic pollutant co-contaminated soil is much larger than that of single contaminated soil.Therefore,the remediation of heavy metal-organic pollutant co-contaminated soil in China is an urgent problem that needs to be solved in environmental protection field.For this reason,this paper firstly introduced the current situation of heavy metals and organic pollutants co-contamination in soil,and secondly analyzed the interaction process and correspondingly environmental effects between heavy metals and organic pollutants in soil,and thirdly summarized the research progresses of remediation technologies for heavy metal-organic pollutant co-contaminated soil from three sides including physical-chemical remediation,bioremediation and joint remediation,and finally proposed the future research directions of remediation of heavy metal-organic pollutant co-contaminated soil.
