摘要
面对土壤重金属污染问题,迫切需要采取措施来修复重金属污染土壤并将其资源化。通过文献调研,旨在阐明我国目前土壤重金属污染的状况,阐述了重金属污染土壤常见的修复方法,包括物理修复、化学修复、生物修复和联合修复等;并在此基础上,分析了目前重金属污染土壤资源化利用主要方向为土壤化利用、建材化处理及路基填筑,针对当前研究存在的问题提出建议,并对未来研究方向进行展望。
Facing the problem of soil heavy metal pollution,it is urgent to take measures to repair the soil polluted by heavy metals and to resource it.Through literature research,this paper aims to clarify the current situation of heavy metal pollution in soil in China,and expounds the common remediation methods of heavy metal contaminated soil,including physical remediation,chemical remediation,biological remediation and joint remediation.On this basis,it is analyzed that the main directions of resource utilization of heavy metal contaminated soil at present are soil utilization,building materials treatment and subgrade filling.Finally,suggestions are made on the existing problems in current research and the future research direction are prospected.
