重金属污染土壤修复技术探讨

Discussion on remediation technology of heavy metal contaminated soil

土壤重金属污染日趋严重,给生态环境和人体健康构成严重威胁,研究土壤重金属污染修复技术对保障人体健康和环境可持续发展具有重要意义。本文在概述土壤重金属污染类型、来源、特点、危害的基础上综述了国内外有关重金属污染土壤修复技术,分析了不同修复技术的特点,并针对各种修复方法,阐述了其修复条件、原理、应用实例,重点论述了生物修复的机理和应用。

Heavy metal pollution incidents happened frequently,becoming more and more serious in our country, and they had serious impact on ecological environment and human health. How to control heavy metals-contaminated soil becomes one of the noted environmental problems. The present paper aims to provide a critical review on the technology of soils contaminated by heavy metals, At the same time, the domestic and foreign typical remediation practices of heavy metals- contaminated soil are On this basis, the future development of remediation technology of heavy metal contaminated soils was prospected.
