地下水源热泵系统以其优越的节能性和环保性在全国范围内得到了推广应用,为了准确地了解地下水源热泵回水对地下水质的影响,本文以安阳市第五人民医院地下水源热泵系统为例,采用TOUGHREACT建立反应物迁移转化模型,对水源热泵系统长期运行中地下水化学组分、含水介质中矿物组分和矿化度的变化情况进行模拟研究。研究结果表明:水源热泵抽回水过程中地下水组分浓度(K~+、Na~+、Ca~(2+)、Mg~(2+)、HCO_3~-)变化程度较小;含水介质中的方解石和云母均发生了不同程度的沉淀作用,钙长石矿物发生了溶解作用;回水井周边的含水介质孔隙度变小,预测期内孔隙度降低了0.0011。水源热泵系统的长期运行对地下水化学组分、含水介质中的矿物组分和孔隙度的影响较小。
Groundwater source heat pump system for its superior energy saving and environmental protection in the country has been popularized and applied, in order to accurately understand the groundwater source heat pump backwater on the impact of underground water quality, this article Anyang Fifth People’s Hospital groundwater source heat pump system is In the case of TOUGHREACT, a model of reactant transfer and conversion was established to simulate the changes of groundwater chemical composition and mineral content in the long-term operation of water source heat pump system. The results show that the concentration of groundwater (K ~ +, Na ~ +, Ca ~ (2 +), Mg ~ (2 +), HCO_3 ~ Of calcite and mica all have different degrees of precipitation, the calcite feldspar minerals dissolve; backwater wells around the porosity of the aqueous medium becomes smaller, reducing the porosity of the forecast period of 0.0011. Long-term operation of the water source heat pump system has less effect on the chemical composition of groundwater, mineral composition and porosity in aqueous media.
