地下含水层储能和地下水源热泵系统中地下水回路与回灌技术现状

Development of ground water loop for ATES and ground water source heat pump systems

介绍了国内外有关技术发展现状及存在的一些技术和环境问题。就地质条件、回灌方式、地下水灌抽比、回扬和洗井次数等指标 ,比较了目前国内和荷兰的技术差异。指出解决地下水回灌的堵塞问题是地下含水层储能和地下水源热泵技术得以发展的关键。强调为避免出现地面沉降和地下水质污染等问题 ,必须采用回灌技术和密闭系统。对政府今后的管理工作提出了一些建议。

Presents the development in the technology and existing technical and environmental problems. According to some indexes including hydrogeologic conditions, injection mode, ratio of injection quantity to extraction quantity of ground water and flushing and washing frequency, compares present technical differences between China and Netherlands. Points out that solving clogging problem during ground water injection is the key to developing ATES and ground water source heat pumps. Emphasizes the appliance of injection technology and sealed systems to prevent ground setting and ground water being polluted. Puts forward some advices for better governmental management.
