钢铁行业重金属污染土壤修复技术及展望

Technology and prospects for soil remediation of heavy metal pollution in the steel industry

钢铁行业在烧结、冶炼和轧钢的生产过程中会产生的大量重金属污染物,通过大气沉降及废渣渗滤等方式进入土壤。本文对钢铁行业土壤污染状况及重金属污染场地土壤修复技术进行系统介绍,比较了各种重金属污染土壤修复技术的适用范围、特点及优缺点,并介绍了技术的研究进展。

The steel industry generates a large amount of heavy metal pollutants during the production process of sintering,smelting,and rolling,which enter the soil through atmospheric sedimentation and waste residue infiltration.This article provides a systematic introduction to the soil pollution situation in the steel industry and soil remediation technologies for heavy metal contaminated sites.It compares the applicable scope,characteristics,advantages and disadvantages of various heavy metal contaminated soil remediation technologies,and introduces the technological research progress.
