摘　　要：地下水循环井(Groundwater Circulation Well,GCW)作为一种原位修复技术近年来引起了广泛关注。该技术可以耦合吹脱、空气注入、气相抽提、生物修复和化学氧化等多种修复技术,有望实现轻非水相液体(LNAPL)、重非水相液体(DNAPL)及部分无机物的同步去除。GCW修复技术充分利用了井内空间安装处理装置,有效避免了传统抽出处理技术能耗高、扰动大的缺陷,为地下水原位修复开辟了新思路。综述了GCW修复技术的研究现状和应用进展,梳理和总结了该技术的基本原理及系统组成,提出了GCW修复技术研究与应用所面临的关键问题和主要挑战,并对该技术未来的研究发展方向进行了展望,以期为场地地下水有机污染原位修复技术研究提供参考。Groundwater Circulation Well(GCW)as an in situ remediation technology has attracted widespread attention recently.Various technologies such as blow off,air injection,gas phase extraction,bioremediation and chemical oxidation are combined in GCW to achieve the remediation of various pollutants,such as Light Non-Aqueous Phase Liquid(LNAPL),Dense Non-Aqueous Phase Liquid(DNAPL)and some inorganic substances in groundwater.GCW remediation technology makes full use of the treatment device installed in the well space,and effectively avoids the defects of the traditional extraction and treatment technology,such as high energy consumption and large disturbance,and opens up a new idea for the in situ remediaiton of groundwater.In this review,the research status and latest progress of GCW remediation technology are systematically reviewed.The basic principle and system composition of GCW remediation technology are summarized.The key problems and main challenges of GCW repair technology research are proposed,and the prospects are also given.The review aims to provide a useful reference for the research on in situ remediation technology of groundwater pollution.
