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。
Water withdrawal from the banks of the river is one of the most common forms of groundwater supply, but water quality in the water area is often at risk from river pollutants. In recent years, with the decrease of regional groundwater level and the change of mining conditions, the form of groundwater recharge by river water also tends to diversify, which affects the migration of pollutants. Based on the analysis of various relationships between river water and groundwater, this paper presents various modes of groundwater pollution by river water, and then concludes its mathematical model and its solution. Finally, it illustrates its application process by examples.
