摘　　要：分析了生活污水在管内换热的机理。采用热电偶温度计直接测量的方法,对重庆市某小区生活污水管道的污水温度进行了现场测试,分析了污水温度变化的原因。利用污水温度日较差和温度变化标准差等评价指标,研究了不同地点污水温度波动情况,并分析了原因。基于分析结果,对污水源热泵系统取水点设置进行了探讨。Abstract： The heat transfer mechanism of sewage in the pipes was analyzed. It was found that the heat transfer was associated with a variety of factors and the effects of the air above the sewage on its temperature varied with seasons. The all-day temperature of sewage in pipes of one residential quarter in Chongqing was measured by a thermocouple thermome- ter. And the reasons of temperature variation were analyzed. The temperature variation of sewage in different sites was studied by using daily range temperature, standard deviation and etc. The reasons were analyzed as well. Based on the conclusion, the selection of the intake point of sewage source heat pump system was discussed.
