地下水污染控制与修复是场地修复的重点内容。我国在地下水污染控制与修复领域尚处于起步阶段,简述了我国地下水污染场地类型、污染特点以及国外地下水污染控制与修复的主要技术,重点研究整理了国外最为常用的地下水修复技术,即抽出处理技术的技术原理、适用条件、技术优势和限制条件,以及系统设计与运行重点关注内容,为我国的地下水污染控制与修复技术研究和工程实践提供参考。
Groundwater contaminant control and remediation is significant part of contaminated site remediation. In China,there is little experimental or practical research on groundwater contaminant control and remediation,which has been studied aboard for decades. This paper briefly presents the types and characteristics of groundwater contaminated site in China,and introduces common technologies used in U. S. superfund sites. Furtherly,the most frequently-used technic,pump and treat,is reviewed and described in detail in this paper,including its technical principle,applications,restrictions and what need to focus on when designing and operating a PT system,which provide the reference for research on groundwater pollution control and remediation technologies and engineering practice.
