摘　　要：城市污水的水参数特性是污水源热泵系统的重要设计依据,应用方法的选择关系到系统运行的可靠性与经济性。针对堵塞与换热问题,将污水水质划分为特大尺度、大尺度与微尺度型并作了实测。分析了水温对系统的影响,变化1℃,影响能耗或投资3%;实测了不同区域、季节的水温变化,不同区域相差较大,水温随季节相对稳定。实测了污水水量变化规律,统计了污水水量特性,日时水量变化达40%,排水建筑面积与可供暖空调建筑面积比为6.4∶1。分析归纳了目前的应用方法,综合对比了其特点,均存在可靠性与局限性。The characteristics of sewage parameters is a important basis of design for sewage source heat pump system . Its application methods will influence the operating reliability and economy. Aimed at the problem of block and heat exchange,the quality of sewage is classified into the largest, larger and miniature. The effect of sewage temperature o system is analyzed. The analytical results show that 1% change has a 3 per cent influence on the energy consumption or invests. The changing of sewage temperature is investigated in different regions and seasons. The result indicates that the sewage temperature is relatively stable in different seasons. Meanwhile, the changing of sewage quantity and the characteristics are surveyed, the sewage quantity daily change reaches 40 per cent, the ratio of the drainage buioding area and air conditioning building area in the heat supply is 6.4：1.After analyzing and contrasting, it is found that there are the reliability and limitation for current application methods.
