摘　　要：土壤中六价铬(Cr(Ⅵ))由于去除难度大、危害性强、水溶性高、迁移速率快、以阴离子基团形式存在等原因备受关注。介绍土壤中Cr的来源、污染现状、危害、价态及形态转变、污染场地风险评估等;综述微生物修复、植物修复、电驱动修复、吸附材料修复等能够从土壤中彻底去除Cr(Ⅵ)的原位修复技术的研究进展,总结和评价现有土壤Cr(Ⅵ)污染修复技术的优缺点及应用现状。从工程应用、土壤Cr(Ⅵ)污染程度、土壤质地、修复成本等角度,提出合适的土壤Cr(Ⅵ)污染修复方案,并对未来土壤Cr(Ⅵ)污染修复技术的发展作出展望。Hexavalent chromium(Cr(VI))in the soil has attracted much attention due to its difficulty in removal,strong hazard,high water solubility,fast migration speed and existence in the form of anion groups,etc.The source of Cr,the status of soil Cr pollution,the harm of soil Cr,the valence state and form transformation of Cr in soil,and the risk assessment of Cr contaminated sites are introduced.The research progress of in-situ remediation techniques that could completely remove chromium ions from the soil are focused,such as microbial remediation,phytoremediation,electric drive remediation,and adsorption remediation.The advantages,disadvantages and application status of existing remediation technology of Cr(VI)contaminated soil are summarized and evaluated.Appropriate remediation schemes are proposed from the perspectives of engineering application,soil Cr(VI)pollution degree,soil texture,remediation cost and so on.And the development of soil Cr(VI)pollution remediation technology in the future is prospected.
