重金属-有机物复合污染土壤修复研究进展

Advances on Remediation of Heavy Metal-Organic Co-contaminated Soil

重金属-有机物复合污染是一种普遍的土壤污染形式,由于重金属和有机物之间存在复杂的互作关系,且污染物特性导致其在修复机理上存在明显的差异,加大了修复难度,因此亟需开发相应的技术对其加以遏制。该文在前人研究的基础上,从复合污染现状、实用修复技术、不同场地与修复技术选择三个方面对重金属-有机物复合污染土壤修复方法进行综述,最终对土壤修复技术提出展望。

Heavy metal-organic co-contaminated is more common in soil contamination. Due to the complex interactions between heavy metals and organic compounds, and the characteristics of pollutants cause significant differences in the remediation mechanism, which increase the difficulty of soil remediation. Hence, it is urgent to develop appropriate technologies to contain it. This publication reviews the remediation methods of heavy metal-organic co-contaminated soil from three aspects that co-contaminated status, practical remediation technology, and technology selection of different sites, then we also puts forward the prospect of soil remediation technology.
