摘　　要：以国内外关于铬污染场地调查和修复技术研究的文献和案例为基础，分析了基于不同场地调查目标和数据获取需求所适用的调查布点及数据分析方法，总结了铬在不同类型污染场地中的残留浓度和分布规律，综述了国内外已经工程应用和正在研究中的针对于重金属铬污染场地的修复技术，并阐述了其各自的适用特点，最后提出了铬污染场地的调查和修复工作中存在的问题和发展方向。On the basis of the relevant literatures published domestically and abroad in recent years, including the development trend, this article tries to deal with Cr contaminated sites in terms of investigation methods, contamination distribution, and remediation methods. Firstly, we have made a summary of the point selection and data analysis methods in response to the different information demands for the site investigation. Secondly, we have divided the typical Cr-contaminated sites into four categories, such as the chrome salt plants, the left area, the waste dumping sites, and the user plants, according to the investigation results gained from the various sites. Along with the Cr-contaminated sites, analysis has also been carried out to find the Cr contamination levels and distribution features, respectively. Thirdly, the article has made a detailed review of the remediation means including the physical-chemical technologies and biological technologies for the different Cr-contaminated sites, while pointing out their respective advantages and disadvantages by giving a list of the Cr versions as a reference to determining their application range. Finally, research directions and development trends in the field have been provided with our comments. Thus, this article has given more clues to the efficient investigations for these potential contaminated sites and further remediation technologies so as to promote a full-fledged research on contaminated site investigation and remediation system.
