尾矿污染区的植物修复研究进展

The Progress of Phytoremediation in Contaminated area of Mine tailings

植物修复是尾矿污染区土壤修复的常用技术。该技术可在稳定被污染土壤及防止地下水二次污染的同时修复污染土壤,既不破坏污染土壤结构,又减少修复费用,因此已成为重金属污染修复技术的研究热点。尾矿污染区植物修复有两种主要作用方式:植物萃取和植物稳定。本文对不同气候条件下两种植物修复方法的优缺点及其适用条件进行了讨论,并对植物修复技术最新研究动态和今后研究方向进行了阐述。

Phytoremediation is an emerging technology for the remediation of of the research of heavy metal contamination recovering technology, beacuse taminated soil and do not destroy the construction of contaminated soil while mine tailings. It this technology has become a hot spot could recover the conmaking contaminated soil stabilize and stopping groundwater from second - time contaminating. There are two approaches to phytoremediation of mine tailings,phytoextraction and phytostabilization. This review discussed the advantages and disadvantages of the both techniques within the context of some specific climate types. Finally, the development trend of phytoremediation technology is put forward.
