摘　　要：六价铬是一种典型高毒性重金属污染物,其水溶性高、迁移性强、治理难度大。对土壤六价铬污染的来源进行了总结,围绕治理修复技术的研究和应用现状进行了综述,结果发现:在实际应用最广的为化学还原技术、固化/稳定化技术和植物修复技术;联合修复技术比单一技术有更好的适应性,微生物/植物修复技术与风险管控技术相结合将具有广阔的市场应用前景;修复装备的智能化和数字化将极大地推动土壤修复行业的发展。加强源头监管、防治结合,才能从根本上解决土壤污染问题。Hexavalent chromium is a typical heavy metal pollutant with high toxicity,high water solubility,strong migration and difficult treatment.This paper summarizes the sources of soil hexavalent chromium pollution,and summarizes the research and application status of remediation technology.It is found that chemical reduction technology,solidification/stabilization technology and phytoremediation technology are the most widely used in practice.The combined remediation technology has better adaptability than the single technology.The combination of microbial/phytoremediation technology and risk management and control technology will have broad market application prospects.The intelligence and digitization of remediation equipment will greatly promote the development of the soil remediation industry.Strengthening the combination of source supervision and prevention can fundamentally solve the problem of soil pollution.
