国内重金属污染土壤修复技术研究进展

Research Progress of Domestic Heavy Metal Contaminated Soil Remediation Technology

随着工农业的发展,土壤重金属污染问题日益严峻。土壤重金属污染具有持久性、无法自然降解、处理难度大等特点,对于工农业生产和人类健康造成了巨大威胁。因此,重金属污染土壤修复技术的发展显得尤为重要。土壤修复技术在国外发展较早,在国内仍处于起步阶段。本文介绍了目前国内主流的重金属污染土壤修复技术,阐明了各技术的优缺点,综述了国内的研究进展情况。为以后土壤修复技术的研究提供借鉴。

With the development of industry and agriculture, the problem of heavy metal pollution in soil has become increasingly severe. Soil heavy metal pollution is persistent, cannot be degraded naturally, and is difficult to deal with. It poses a huge threat to industrial and agricultural production and human health. Therefore, the development of heavy metal contaminated soil remediation technolo-gy is particularly important. Soil remediation technology developed earlier abroad and is still in its infancy in China. This article introduces the current mainstream domestic heavy metal con-taminated soil remediation technologies, clarifies the advantages and disadvantages of each tech-nology, and summarizes the domestic research progress, which provides reference for future re-search on soil remediation technology.
