    RESEARCH PROGRESS ON REMEDIATION TECHNOLOGY OF CHRO-MIUM CONTAMINATED SOILS AND GROUNDWATER IN SHANGHAI

    • 摘要: 上海20世纪70年代含铬废水排放量大,其中六价铬毒性大、溶解度高、迁移性强,极易随水淋溶污染地下水系统。开展高效、经济的土壤和地下水中铬污染修复方法的研究,具有重要的现实意义。本文系统地综述了铬污染场地修复技术现状,包括还原稳定、渗透反应墙、电动修复、生物修复等,重点探讨了上海地区污染深度大于4m的低渗透性的铬污染场地电动反应墙联合修复技术的发展趋势。

       

      Abstract: In the 1970s, a large volume of chrome-containing wastewater was discharged into ground in Shanghai. Hexavalent chromium has the characteristics of high toxicity, high solubility and strong mobility. It can easily contaminate groundwater system. Efficient and economic remediation methods are of great significance. This paper systematically summarizes the remediation status of hexavalent chromium. They include reduction and stabilization remediation, permeable reactive barrier, electrokinetic remediation and biological remediation. It is appropriate to take electrokinetic reactive barriers with strengthening reagent in low-permeability soil when deeper than 4m below ground surface.
