微生物在重金属污染土壤修复中的作用研究

Research on the Role of Microorganisms in the Remediation of Heavy Metal Contaminated Soil

在环境工程的发展过程中,修复重金属污染土壤是重要的研究方向之一。当前,就我国的环境污染状况来看,重金属污染占有较大比重,且对土壤环境造成了严重危害,因此,修复重金属污染土壤刻不容缓,而在诸多的土壤修复技术中,微生物修复技术具有良好的修复效果。本文首先对微生物重金属污染修复技术进行了概述;然后分析了微生物修复在重金属污染土壤中的三种作用,最后对微生物在重金属污染土壤修复中的实际应用展开了研究。

In the development of environmental engineering,remediation of heavy metal contaminated soil is one of the important research directions.At present,in terms of China5s environmental pollution,heavy metal pollution occupies a large proportion,and has caused serious harm to the soil environment,therefore,it is urgent to restore the heavy metal contaminated soil.Among many soil remediation technologies,microbial remediation technology has a good remediation effect.In this paper,the remediation technology of microbial heavy metal pollution is summarized firstly.Then three functions of microbial remediation in heavy metal contaminated soil were analyzed.Finally,the practical application of microbial remediation in heavy metal contaminated soil was studied.
