矿区重金属污染土壤的修复技术研究现状

Study on Mining Area′s Heavy-metal Soil Pollution Remediation Technology

矿山开采引发的矿区及周边土壤重金属污染已成为严重的环境问题之一。目前重金属污染土壤修复主要采用物理化学技术和植物修复技术,从这2方面较全面地介绍了国内外矿区重金属污染土壤的治理方法,并提出矿区土壤污染治理存在的问题和今后的发展方向。

Heavy metal soil pollution caused by mining activities has become one of the most serious environmental problems. At present physical chemistry technology and phytoremediation are the important methods for solving this problem. This paper specifically introduces the control methods at home and abroad from the two aspects and puts forward the problems existed in the soil pollution control, as well as the development orientation in the future.
