摘　　要：针对地下水氯代烃污染修复最为常用的七种技术进行了比较,各项修复技术适用范围有所区别,根据地下水污染物种类、污染程度、地质条件等的不同,可以针对性的选择最为适合的修复技术,各项之间也可以联用以达到更好的修复效果。通过对比发现,抽出处理技术和渗透反应墙技术可用于对污染物扩散范围的控制,原位曝气技术、生物修复技术和化学氧化技术可以针对地下水污染源区进行修复,植物修复技术和监测自然衰减技术可用于微污染区域的长期修复。Seven technologies on restoring the groundwater contaminated by chlorinated hydrocarbon were compared. The ap- plication scope of each technology was different. According to the types of the contaminant, the degree of contamination, and the geological conditions, the suitable remediation technology could be chosen. These technologies could also be utilized conjunctive- ly. From the comparison, pump and treat technology and permeable reactive barrier technology were suitable for controlling the diffusion range of the contaminant. In - situ air sparing technology, bioremediation technology and chemical oxidation technology were suitable for restoring the source of contamination. Phytoremediation technology and monitored natural attenuation technology were suitable for long duration remediation on slightly polluted area.
