摘要
傍河取水是常见的地下水供水形式之一 ,但水源地的水质常常受到河流污染物的威胁。近年来 ,随着区域地下水位的下降和开采条件的变化 ,河水补给地下水的形式也趋于多样化 ,从而影响着污染物的迁移。本文通过对河水与地下水的各种关系的分析 ,给出了河水污染地下水的各种模式 ,并综合得出其数学模型及其解 ,最后用实例说明其应用过程。
The pumping of groundwater beside the river is one of the common types of groundwater supply. Nevertheless,the water quality is commonly threatened by pollutants in the river. In recent years,with the lowering of groundwater table in the region and the changing of exploitation condition,the types which the river recharges groundwater tend to become varied,which affects the migration of pollutants.Through the analysis of various relations between river water and groundwater,the models by which the river water pollutes groundwater and the related math models as well as their solutions are given in this paper.Finally,a practical example is used to illustrate the process of application.
