Abstract: The affiliated hospital of Guiyang Medical University was the first organization using the application of sewage heat pump system to cool and heat. After its emergency building took the new sewage heat pump to replace the original geothermal heat pump, there was obvious effect on the energy saving. Compared with the previous year in which the sewage heat pump was not improved, the new sewage heat pump not only reduced the cooling and heating energy consumption costs, but also substantially reduced emissions of air pollutants. The new sewage heat pump played a very good example in the application of clean energy, and it is of great significance on the recycling economy and environmental protection.

Abstract: Reclamation and application of sewage heat energy is a good choice for sustainable development and an effective mean of energy-saving and output-reducing. By analyzing the capacity, temperature and quality of sewage of Guiyang, we obtained the basic conditions for the application of sewage heat energy in Guiyang. The results showed that the sewage of Guiyang was resourceful, and have occurrence of large amount of cold (hot) energy. There was an obvious temperature difference between sewage temperature and atmosphere temperature. Sewage was lightly corrosive. The application conditions of sewage heat energy were suitable. Sewage heat is a clean energy which is easy to recycle. Three factors, including capacity, temperature and quality of sewage, are considered if sewage heat energy was applied. 3 factors of 10 sewage treatment plants and their subsidiary pipe network in Guiyang were monitored and analyzed to verify the application conditions of sewage heat energy in Guiyang. From the perspective of energy-saving and output-reducing, an effective way is explored to develop new energy sources in Guiyang[1,2].
