某地下水源热泵诱发地下水水质变异成因分析

为了研究地下水源热泵的"抽—回"系统运行过程中对地下水水质的变化,选择池州某地下水源热泵工程为研究对象,在收集各项目所在地段的水文气象、地质、水文地质和水质资料的基础上,进行水质水化学类型分析以及相关性分析。并根据区域水文地质条件受热泵系统影响机制,进行水质变异成因分析。研究结果表明:水源热泵系统的运行改变了工程所在地段的地下水化学类型;水质变异成因中常规的动力场、温度场和化学场因素影响可恢复,地质结构因素影响不可恢复。

Groundwater Quality Variation Reasons Induced by Groundwater Heat Pumps

In order to analyze the impacts of groundwater heat pumps to groundwater quality,this paper choose a groundwater heat pump located in Chizhou city as an example.After collecting data from hydrology,weather,geology,hydrogeology and water quality,Correlation analysis and hydrochemical type analysis were conducted based on the hydrology,weather,geology,hydrogeology and water quality data.In addition,analysis on the reasons of water quality variance was carried out according to the impact mechanism of the regional hydrogeological conditions.We conclude that groundwater heat pumps could change the surrounding hydrochemical type,power field,temperature field and chemical field factors can be recoverable,while geological structure changes cannot be restored.
