中文摘要:

通过对土壤四氯化碳含量的测试,研究了某水源井附近和某电器设备安装公司厂区土壤四氯化碳污染特征,明确了水源井地下水的污染源和污染途径,分析了土壤四氯化碳污染晕分布的控制因素。在该水源井及厂区附近的钻孔土样中均检出了连续分布的四氯化碳,最高浓度可达46.0 ng/g,在厂区内部四氯化碳主要分布在包气带中,而在厂区外围则主要分布在含水层中。该公司在历史上倾倒在地表的四氯化碳清洗剂,在厂区内通过垂直入渗进入含水层,而后受场地地下水流场的控制,沿地下水主要流向向厂区东部水源井水平运移。现状场地内不存在饱和浓度的四氯化碳污染团(DNAPL Poll)。土壤四氯化碳污染晕的分布主要受污染源的距离、岩性、水动力条件、四氯化碳的自然降解和水源井抽水等因素的控制。

英文摘要:

Through measurements for the carbon tetrachloride(CTC) content in the soil,this paper studied the characteristics of CTC pollution in the soil near a water source well and in an electric equipment installing company,cleared the sources and channels of groundwater pollution,and analyzed the controlling factors of CTC pollution plume distribution in the soil.Continuous distributions of CTC were detected in the drill hole soil samples near the water source well and the company with a top concentration of 46.0 ...
