摘要
水源热泵系统的开发利用与地下水环境息息相关。为了给研究区水源热泵项目的进一步开发和利用提供参考,从地下水动力场、地下水温度场、地下水化学场3个方面探讨了水源热泵系统对地下水环境的影响。其中,地下水水位逐年升高且降落漏斗范围缩小,水源热泵系统对研究区地下水动力场没有影响;地下水温度整体稳定,局部地热单供暖区水温有下降趋势,回灌水温差对研究区地下水温度场有局部影响;该系统导致地下水蒸发作用强烈,Cl^(-)和SO_(4)^(2-)含量不断增大,水化学类型由HCO_(3)-Ca·Mg转变为HCO_(3)·Cl·(SO_(4))-Ca·Mg。研究表明,定期监测地下水指标与合理设置地热开采量,可显著降低水源热泵系统对地下水环境的不利影响,促进水源热泵系统的推广应用和可持续发展。
The development and utilization of water source heat pump systems are closely related to the groundwater environment.In order to provide reference for the further development and utilization of water source heat pump projects in the research area,this article explores the influence of water source heat pump systems on groundwater environment from three aspects,including the groundwater dynamic field,the groundwater temperature field,and the groundwater chemical field.Among them,the groundwater level has been increasing year by year and the range of the falling funnel has been reduced.The water source heat pump system has no effect on the groundwater dynamic field in the study area;The groundwater temperature is generally stable,and there is a downward trend in the water temperature of the local geothermal single heating area.The temperature difference of the recharge water has a local impact on the groundwater temperature field in the study area;This system leads to strong evaporation of groundwater,increasing the content of Cl^(-)and SO_(4)^(2)-,and changing the hydro-chemical type from HCO_(3)-Ca·Mg to HCO_(3)·Cl·(SO_(4))-Ca·Mg.The research shows that regular monitoring of groundwater indicators and reasonable setting of geothermal mining output can significantly reduce the adverse impact of water source heat pump system on groundwater environment,and promote the popularization and application of water source heat pump system and sustainable development.
