摘　　要：以某山谷型垃圾填埋场垃圾渗漏液泄漏的地下水污染调查与污染风险管控过程为例,探讨山谷型水文地质条件小尺度场地下含水层非均质性对地下水污染特征的控制作用。通过对研究区水文地质勘查、地下水污染的精准消源控羽和含水层强径流带的高效刻画等实践结果表明:山谷区非均质含水层中“非菲克弥散”现象明显;场地含水层非均质的掌控是地下水污染管控与修复工程成败与优化的关键所在;含水层非均质的把控可明显提高地下水污染精准管控效果,同时还可大大降低管控成本。本案例可为山谷型地下水污染风险管控工作提供可供借鉴的实践经验和技术参考。Taking the process of groundwater pollution investigation and pollution risk control of a valley-type landfill with waste leakage as an example,the control effect of aquifer heterogeneity on groundwater pollution characteristics in a small-scale site with valley-type hydrogeological conditions was discussed.The results of hydrogeological exploration,precise source and plume control of groundwater pollution and efficient characterization of the strong runoff zone of the aquifer showed that the phenomenon of"non-Fick dispersion"was obvious in the heterogeneous aquifer in the valley area.The control of site aquifer heterogeneity was the key to the success and optimization of groundwater pollution control and remediation projects.Aquifer heterogeneous control could significantly improve the precision control effect of groundwater pollution,but also greatly reduce the control cost.This combined case could provide practical experience and technical reference for valley-type groundwater pollution risk control.
