拦截沟技术在污染地下水风险管控与修复中的应用

Application of Interceptor Trench in Risk Control and Remediation of Contaminated Groundwater

拦截沟是一种有效的地下水修复和风险管控技术,但该技术目前在我国工程应用和相关研究较少。拦截沟设计和构筑方法的基础是现有的水文地质理论研究和工程实践。本文综述了拦截沟的技术原理、适用范围和设计要点,并结合工程实际总结施工与运行要点,阐明了该技术的应用现状,明确了该技术的应用前景及今后进一步研究发展的方向。

Interceptor trench is an efficient technique to remediate the contaminated groundwater and control the risk.However,the technique is neither widely used nor researched in China.The design and the construction of the interceptor trench are based on the state-of-art hydrogeological theory and engineering practice.This review summarizes the technical principles and the scope of application as well as the key points of the interceptor trench design.Considering of the practical experience,this article also reviews the construction and the operation of interceptor trenches,thus clarifying the application status.Finally,the prospects of the technique and the further research direction is proposed.
