| 摘 要： | 为了深入了解垃圾渗滤液对浅层地下水污染的机理,揭示不同龄期垃圾渗滤液在浅层地下水中多组分运移规律,文章以阜新市垃圾填埋场为研究对象,通过室内土柱对比实验,研究了不同龄期垃圾渗滤液在浅层地下水中多组分运移的机理和规律。结果表明不同龄期垃圾渗滤液在入渗过程中都会引起地下水不同程度的污染,且新鲜垃圾渗滤液较老龄垃圾渗滤液更易污染地下水,其污染机理主要为吸附、解析、溶解、沉淀和离子交换等水岩作用。研究结果为今后垃圾填埋场的治理和地下水的修复提供理论依据。

| Abstract: | In order to learn more about the underground water contamination mechanism by garbage leachate, and disclose the transport regularity of leachate components of different periods in underground water, The paper taking Fuxin Garbage Plant as an example, through soil colum contradistinctive test, showed that the leachate in different periods would contaminate groundwater in the process of infiltration more or less. The fresh leachate had a stronger pollution ability to groundwater. The principal pollution mechanism of leachate components was water-rock interaction, such as adsorption, desorption, dissolution, precipitation and ion exchange. The experiment provided a theoretical basis for harnessing the landfill plant and repairing groundwater in the future. |
