doi:10.11924/j.issn.1000-6850.casb2021-0374

Abstract

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
