摘要:

20世纪90年代以来,土壤重金属污染日益严重,微生物修复作为一种新兴的土壤重金属修复技术,当前已经成为土壤重金属修复领域的研究热点。本文主要讲述了当前重金属污染的发展趋势以及治理过程中存在的技术问题,重点阐述了微生物修复农田土壤重金属污染机理以及微生物与钝化剂、植物联合修复农田土壤重金属技术的应用情况和实施效果,并提出了制定行业标准和完善微生物联合修复技术的相关建议。

关键词: 土壤, 重金属, 微生物, 农田污染, 联合修复

Abstract:

Since the 1990s, soil heavy metal pollution has become increasingly serious, microbial remediation as a new soil heavy metal pollution remediation technology has become a research hotspot in soil remediation. This article mainly described current development trend of soil heavy metal pollution and the technical problems existing in the remediation process, and focused on the mechanism of microbial remediation of heavy metal pollution in farmland soil, as well as the application and implementation effects of microbes combined with passivators and plants in the remediation of heavy metal polluted farmland soil. At the same time, this article put forward relevant suggestions on formulating industrial standards and improving the microbial remediation technologies.

Key words: soil, heavy metal, microbes, farmland pollution, combined remediation
