摘要: 为了解地下水源热泵运行对地下水环境（地下水化学、水质及微生物）的影响，本文利用沈阳市已建地下水源热泵工程场地，对回灌井定期（2013年7月至2015年10月）监测水质及微生物，并对监测数据进行分析.结果表明：水源热泵系统运行对地下水化学类型（由HCO3·SO4-Ca·Mg型变化为监测早期的HCO3·SO4·Cl-Na·Ca及监测后期的HCO3·SO4-Na·Ca·Mg型）及微生物的生长速率（温度变高或变低均抑制微生物的数量）产生了一定的影响；对地下水中稳定化学组分的浓度影响不大，对"三氮"及Fe、Mn浓度产生波动，导致地下水质量等级略有变化.因而今后工作还需进一步加强热泵系统运行对地下水环境影响监测.Abstract: To study the effect of groundwater heat pump(GWHP) on groundwater environment, including hydrochemistry, water quality and microorganism, the paper analyzes the data from the interjection wells at regular intervals from July 2013 to October 2015 at a GWHP monitoring site in Shenyang. The result shows that GWHP has certain influence on the chemical types of groundwater (changing from the initial HCO3·SO4-Ca·Mg to early HCO3·SO4·Cl-Na·Ca, then to later HCO3·SO4-Na·Ca·Mg during the monitoring process) and growth velocity of microorganism controlled by temperature; the effect on the concentration of stable chemical compositions is little, while the concentration fluctuations of "three-nitrogen", Fe and Mn lead to the slight change of groundwater quality grade. Therefore, it is necessary to strengthen the effect monitoring of GWHP on groundwater environment.
