Heat Utilization Of Urban Sewage In Chongqing

With the rapid growth of population,economic development and social progress,which aggravate the energy consumption, environmental pollution and destruction.Looking for renewable clean cool or heat source has increasingly become the goal. In the utilization of low energy, because of the less temperature variation of urban sewage ,which has the characteristics of warm in winter and cool in summer. Urban sewage easily through the existing urban sewage pipe to collect,so it was recongnized the clean energy in recycling and utilization. Effective utilization of urban sewage recycle heat will be the advanced technology with sewage resource in the future. Base on the characteristics of Chongqing and combined with engineering examples, this paper analysis the feasibility and superiority with utilization of the urban sewage.Firstly, the paper analysis the temperature of the main sewage water pipe in Chongqing. Determine the sewage have the potential application in this city, and introduces the different technology application of using the sewage-source heat pump system in Chongqing. Simply deduced the life displacement in Chongqing, analysis and expunded the feasibility of using sewage-source heat with huanle square in Donghe chuntian. For project intends to adopt sewage-source heat pump system or conventional air-conditioning system. Estimating and compared costs of the annual operation, calculation and analysis the saving energy and water. At last, base on the getting water and drain of the project , the environmental influence was detailed analysis. Draw full-text conclusion, adopt sewage-source heat pump system is feasible of the project. Comepared with the conventional air-conditioning system , the project adopt sewage-source heat pump system have prominent energy-saving effect and pro-environment benefit.
