中文摘要： 重非水相液体(DNAPL)污染物是地下水系统中常见的一类有机污染物，对其在地下含水介质中运移规律和修复治理研究是国内外水文地质学和环境科学领域的热点。DNAPL渗入地下含水系统形成多相流，实时定量监测多相流是科学开展地下水系统中DNAPL污染物运移规律和修复治理研究的前提和基础。光透法作为一种经济安全、无损、非侵入的监测方法近年来被用于介质中流体迁移规律监测。本课题拟应用光透法开展多相流实时定量监测的模型和应用系统研究。具体包括：应用光透法建立二相流和三相流条件下的流体饱和度定量模型；光透法在地下水孔隙和裂隙介质条件下的实时定量监测方法和应用；在均质和非均质条件下的应用；在饱和和非饱和条件下的应用；在生物修复和空气扰动修复条件下的应用。

英文摘要： Dense Non-aqueous Phase Liquid (DNAPL) is a kind of popular contaminant in ground water system. Many researchers of hydrogeology and environmental sciences focus on the migration mechanisms of DNAPL and its remediation in subsurface media. Multiphase flow occurs when DNAPL infiltrates unsaturated and saturated subsurface media. Real-time quantitative monitoring multiphase flow is the base and a precondition for scientific study on migration mechanisms and remediation methods and techniques of DNAPL in ground water system. Light transmission method is applied to monitor fluid flow in media recent years with advantages of economy, safety, non-destructive and non-invasive technique. Light transmission method will be applied to real-time quantitatively monitor multiphase flow in this project. Objectives of this project include: models of fluid saturations by light transmission method in conditions of two-phase flow and three-phase flow, models and application light transmission method in porous and fractured media, application in homogeneous and heterogeneous porous media, application in saturated and unsaturated media, application in conditions of bioremediation and air sparging。
