摘要
从水质、水温、水量等几个方面介绍了城镇污水的特点,简要分析了热泵的工作原理与分类、优点及其发展。阐述了以城镇污水为热源的热泵系统的可再生性、高效节能、含热量大及用途广泛等特点。分析了适宜推广应用污水源热泵技术的多种场合。通过对以污水处理厂二级处理水为热源的区域供热供冷系统的探讨,对污水源热泵系统进行了简要介绍。
Traits of urban wastewater were introduced from the aspects of water quality, temperature and quantity. Work elements, sort, merit and development of heat pump were illuminated. Traits of heat pump system with urban wastewater were presented sneh as reproducible, energy efficieney, plentiful heat energy and wide use. A variety of occasions where the application of water-source heat pump technology can be appropriate to promote were analyzed. Through analyzing the district heating and cooling system, whieh takes secondary treatment water of wastewater treatment plant as heat source, the wastewater source heat pump system was introduced.
