摘　　要：废弃取水井封井回填可切断井周边污染源对深层地下水的污染通道和污染途径,有效防止周边污染源对区域地下水造成污染,降低地下水环境污染风险,全力保障地下水生态环境安全。本文在地下水污染源分析的基础上,以深圳市大鹏新区某废弃取水井为例,通过全面调查,在掌握废弃取水井特点的基础上,确定全井回填技术作为封井回填的技术路线,并对回填意义进行了初步分析。Sealing and backfilling can cut off the pollution channels and ways of deep groundwater polluted by the pollution sources around the well,effectively prevent the pollution of regional groundwater,reduce the risk of groundwater environmental pollution,and make every effort to ensure the safety of groundwater ecological environment.On the basis of the analysis of groundwater pollution sources,this paper takes a abandoned water well in Dapeng New District,Shenzhen as an example,through comprehensive investigation,on the basis of mastering the characteristics of abandoned water well,and the whole well backfill technology is used as the technical route of well sealing backfill,and makes a preliminary analysis of the significance of backfill.

关 键 词：废弃取水井 封井回填 生态环境安全
