Sewage source heat pump and waste water source heat pump is an important tool for the energy cycle, heat pump technology in applications worldwide and has been the rise of more than 60 years of history, in China there are more than 10 years of history. However, since the majority of the urban world is very short of land resources, leading to lack of groundwater resources in the city, seriously constrains the water source heat pump and ground source heat pump a wide range of applications. Every city has industrial wastewater and domestic sewage, and municipal wastewater is characterized by the witer cold and summer warm, winter temperatures generally in the 14 c - 19c, the summer temperature has stabilized at around 22c, and the water temperature, water is relatively stable. If raw sewage source heat pump recovery of the heat treatment, can be solved at least three billion square meters of buildings heating problem in winter.

Raw sewage water complex, a large number of sewage mixed with debris. To solve these problems, our company successfully developed a fully automated machine, such as effluent decontamination equipment, not only will the sewage effluent effectively filter out debris and can be filtered using the sewage debris transport the sewage after the heat exchanger Back to the trunk sewers, will not cause secondary pollution, but also to overcome the resistance of sewage debris, such as technical difficulties, the achievement of water, heat recovery, heat pump heating to break the bottleneck.

The system's initial investment and operating cost savings are more than 20% margin. Third, as a result of a machine used (refrigeration, heating and domestic hot water), eliminating the need for ordinary central air-conditioning cooling tower, boiler room or engine room heat exchanger initial net investment; Compared to water-source heat pump, eliminating the need for drilling costs; Compared to ground-source heat pump to save the cost of land and investment.

Raw sewage source heat pump technology is not only energy-saving and environmental protection. Compared with large-scale coal-fired boiler, primary energy use of more than 80% efficiency, unit heat load power consumption to save more than 10 percent of groundwater sources to 50%, than the traditional central air-conditioning system to save 30% - 60% of operating costs. Because the entire system does not need cooling towers, there is no running water in summer evaporation and drift water, 10, 000 square meters to more than 4000 tons of water-saving and the use of one tons of sewage every energy, could reduce the 4.8 kilograms of carbon dioxide emissions, but also reduce the emission of a large number of sulfide, nitride. At the same time, solve the cooling tower or air-cooled cooler operating table noise.
