摘　　要：针对水利水电工程施工场地在岩溶地区、高原地区等复杂地质环境下的地下水污染问题,提出了一种新的控制与修复方法,旨在应对因地质条件导致的污染物迁移加速和扩散范围扩大的挑战。构建地下水中污染物的迁移方程,明确污染物的迁移规律与水流流向的关联性;提出地下水污染的控制策略,设计原位修复技术和异位修复技术。实验结果表明:应用所提方法经过28天的修复治理后,某大型水利水电施工场地地下水污染物中苯的浓度出现大幅度降低,最大程度的苯浓度变化236 mg/L^(-1)下降到了5.36 mg/L^(-1),由此可知研究方法下受污染的地下水得到了有效修复。A new control and remediation method is proposed to address the problem of groundwater pollution in complex geological environments such as karst and plateau areas during the construction of water conservancy and hydropower projects.The aim is to address the challenges of accelerated migration and expansion of pollutant diffusion caused by geological conditions.This paper constructs a migration equation for pollutants in groundwater to clarify the correlation between the migration law of pollutants and the flow direction of water flow.The control strategies for groundwater pollution,design in-situ remediation technologies and ex situ remediation technologies are proposed.The experimental results show that after 28 days of remediation treatment using the proposed method,the concentration of benzene in groundwater pollutants at a large water conservancy and hydropower construction site significantly decreased,with the maximum benzene concentration change of 236 mg/L^(-1) decreasing to 5.36 mg/L^(-1).This indicates that the polluted groundwater under the research method has been effectively remediated.
