针对某城市原生污水源热泵系统污水干渠特殊的地理位置和施工限制,对其污水系统的取水方式进行了研究,详细介绍了该污水源热泵系统的工艺流程、直接取水方式、污水泵选择、首端过滤装置设计等,并针对实际运行中发现的问题改进防阻方法,提出了一种污水干渠内粗过滤防污思路,供原生污水源热泵系统工程参考。
Aiming at the special geographical position and construction restriction of the sewage main canal of a city’s primary sewage source heat pump system, the water intake method of the sewage system was studied. The process flow of the sewage source heat pump system, the way of direct water intake, the selection of sewage pump, End filtration device design, etc., and to improve the method of preventing the problems found in the actual operation, put forward a kind of coarse filter antifouling ideas in the sewage trunk canal for the reference of the original sewage source heat pump system engineering.
