城市污水热能资源化的基础研究

A Basic Research on Heat Energy Resource Stored in Urban Sewage

作为城市污水热能资源化的基础研究,根据理论分析方法,对有效利用城市污水所赋存的热能时,其节能效果和对减轻大气污染的作用进行了若干分析和探讨.分别计算了流量为1 m3/s时城市污水赋存的热量,以及采暖面积为1万m2时所需的城市污水及赋存的热量,与空调、锅炉相比产生相同热量时的一次能和二次能的消减量,以及相应条件下的污染物年间(采暖期)消减量等.

This paper is a basic research on heat energy resource stored in urban sewage. By means of theoretical arithmetic, the author analyzed and discussed that effectively utilizing the heat energy which is stored in the urban sewage could economize energy and have an advantageous effect on reducing air pollution. The author has calculated respectively the saved heat quantity in the urban sewage when the flow capacity is 1m^3/s and the needed urban sewage quantity and heat quantity when the heating areas are 10,000 m^2, and calculate the decrement quantity of primary energy and secondary energy when produces the same heat energy quantity as air conditioning and boiler, as well as the annual（heating period）pollutant decrement quantity under the corresponding condition and so on.
