摘　　要：地下水有机污染点多面广、污染源不清、治理难度大,如何从源头上控制污染源,减少污染源对地下水的威胁,是地下水污染控制和治理的关键.以典型污染场地为例开展有机污染源辨识研究,建立地下水有机污染源识别技术体系,并应用于典型污染场地地下水有机污染源的识别.在掌握污染场地地质、水文地质条件的基础上,从大量地下水分析化验数据中,确定污染场地特征污染物为四氯化碳,建立污染场地溶质运移模型,并结合单体同位素技术,通过模型反演和同位素溯源,确定了典型场地有机污染源的分布、污染现状,并对识别出的潜在污染源进行调查和土壤取样分析,结果表明,辨识出的两个历史污染源位置、污染物浓度分布结果可靠,为地下水污染治理提供了依据.Groundwater organic pollutions are found in large amount of locations,and the pollutions are widely spread once onset;which is hard to identify and control.The key process to control and govern groundwater pollution is how to control the sources of pollution and reduce the danger to groundwater.This paper introduced typical contaminated sites as an example;then carried out the source identification studies and established groundwater organic pollution source identification system,finally applied the system to the identification of typical contaminated sites.First,grasp the basis of the contaminated sites of geological and hydrogeological conditions;determine the contaminated sites characteristics of pollutants as carbon tetrachloride,from the large numbers of groundwater analysis and test data;then find the solute transport model of contaminated sites and compound-specific isotope techniques.At last,through groundwater solute transport model and compound-specific isotope technology,determine the distribution of the typical site of organic sources of pollution and pollution status;invest identified potential sources of pollution and sample the soil to analysis.It turns out that the results of two identified historical pollution sources and pollutant concentration distribution are reliable.The results provided the basis for treatment of groundwater pollution.
