矿区土壤重金属污染修复技术研究进展

Research Progress on Heavy Metal Pollution Remediation Technology in Mining Area

本文阐述了矿区土壤重金属污染修复的物理-化学修复、生物修复、联合修复的修复技术,探讨了各种方法的原理、优缺点和今后努力的方向。展望了以基因工程改良培育超富集和富集类植物微生物动物、多种技术联合修复、制备可以回收利用吸附土壤重金属的稳定剂、合成清洁易降解的洗淋剂,为土壤重金属污染的整治及其生态修复提出新途径。

This paper describes the remediation techniques of physical-chemical repair, bioremediation and combined repair of heavy metal pollution remediation ill the mining area. And discusses the principles, advantages and disadvantages of various methods and the direction. In order to improve the quality of heavy metals used in the adsorption of soils, the preparation of clean and easily degradable eluent will be the main research object. The results showed that the supernatant and enrichment plant microbial animals could be used in the future. Remediation of heavy metal pollution in soil and its ecological restoration.
