Research on Reutilization of Heat Energy from Municipal Wastewater of China

摘要

This paper analyses the heat energy characteristics of municipal sewage and the methods of reclaiming and using the municipal sewage heat energy, recovered energy can be served for heating or cooling. Establishes the economic analysis model based on the annual expenditures method, and carries out the economic analysis of sewage source heat pump heating water system and other heating water system. It is shows that sewage source heat pump system with reclaiming the municipal sewage heat energy has obvious effects of saving energy and environment protection. Also points out the prospect of application of the sewage source heat pump system the system in China.
