植物-微生物联合修复重金属污染底泥/土壤的研究进展

重金属作为一种持久性污染毒物,近年来在中国由其引起的环境污染已引起了高度的关注。植物-微生物联合修复作为一种绿色环保技术,在石油污染土壤治理中的应用研究日益成熟,将该技术应用于重金属污染底泥/土壤的修复已逐渐开展。该文对中国底泥/土壤重金属污染的现状、处理方法等进行了概括,对植物-微生物联合修复的定义、原理进行了阐述,并从微生物类别的角度叙述了目前能用于重金属污染底泥/土壤处理的植物-微生物联合修复技术的几类不同形式,最后对植物-微生物联合修复法在底泥/土壤重金属污染修复中的应用前景进行了展望。

The Research Progress on Plant-microorganism Combined Remediation of Heavy Metals-contami-nated Soil & Sediments

As a kind of persistent toxic,heavy metals pollution has caused a high degree of attention recently in Chi?na.As a green technology,plant-microorganism combined remediation are increasingly mature on its application in the oil pollution of soil,so appllying to the restoration of sediment/soil heavy metal pollution has been gradually car?ried out.This article summarizes the current situation of sediment/soil heavy metal pollution,the processing method and so on.Also the definition,principle about the plant-microorganism combined remediation was expatiated,and the different forms of plant-microorganism combined remediation on plant-microbial was described.Finally ,the ap?plication foreground of the plant-microorganism combined remediation in sediment/soil heavy metal pollution repair was prospected.
