Chlorinated organic pollutants are one of the typical pollutants in the groundwater, and the deeply research and discussion on the PRB technology will be helpful to perfect and improve the in-situ remediation technology that is used to dispose the pollution of chlorinated organic pollutants in the groundwater. In addition, the structure pattern and dechlorinating mechanism of PRB were introduced, and the new research advances of PRB at home and abroad were discussed. Finally, the advantages and disadvantages were concluded, and on the basis of which, the future development directions of PRB were recommended.%氯代有机化合物是一种典型的地下水污染物,对可渗透反应墙技术进行深入的研究和探讨,有利于地下水氯代化合物污染场地修复技术的完善和提高.介绍了可渗透反应墙的结构类型和脱氯机理,讲述了可渗透反应墙技术的国内外研究概况,重点讨论了可渗透反应墙技术的国内外新进展,最后总结了可渗透反应墙技术的优势和不足之处,并在此基础上给出了可渗透反应墙技术的未来发展万向.
