摘要
本文通过对奇村地热田地下水水化学资料及其水化学空间分布特征的分析,解释了本区地下水水化学成分的形成和演化机理;同时运用PHREEQC软件模拟,得出目前开采冷、热水的混合比范围为1.0∶1-3.2∶1,从而为合理开发利用地下热水提供了依据。
It is a general phenomenon that water with different chemical ingredients mix in natural water environment. No matter what its scale is, exploitation drainage of groundwater, which artificially increases the volume of , changes the natural state of equilibrium of groundwater system to some extent. This will be reflected on both the quantity and quality of water. By monitoring the water quality, not only the variety characteristics of water quality will be acquainted with, but the variety of composite of exploiting resources of groundwater. By analysis of the hydrochemical information and the spatial distribution characteristics of the hydrochemistry of groundwater in Qicun geothermal field, this paper illuminates the formation and evolution mechanics of groundwater ingredients, and gives a rational ratio range of mixture being exploited at present between cold water and hot water of I. 0:1 - 3.2:1 by simulating mixture action through PHREEQC software, which provides a scientific basis for the reasonable development and utilization of the hot water resources.
