地下水硝酸盐原位修复技术研究进展

摘要

介绍了地下水硝酸盐原位修复技术,对目前使用较多的渗透反应墙与注射井引入工程实例加以说明.指出原位修复技术不同的适用条件,同时提出浅层地下水系统本身的自然净化机制对大范围的地下水硝酸盐的防治更具经济优势.%This paper focuses on the technologies for insitu remediation of nitrate in groundwater, and describes the commonly used technologies, PRB and injection wells, and their applications. Appropriate conditions for insitu remediation technologies are proposed. It is pointed out that the natural purification mechanism of the shallow groundwater system has the obvious advantage of controlling a wide range of groundwater nitrite.
