The so-called primary sewage is the direct discharge of untreated living or industrial wastewater in the city. At present, the utilization method is that the raw sewage directly enters the sewage source heat pump system for heat exchange, and the indoor building is cooled and heated in the case of consuming a small amount of electricity. There are several technical difficulties in wastewater reuse that need to be overcome: blockage, corrosion, and heat transfer efficiency.
After the urban raw sewage directly enters the sewage heat exchanger for heat exchange, the heat exchanged is transferred to the indoors by the heat pump inside the sewage source heat pump.
The advantages of recycling the city's primary sewage are: energy saving and environmental protection, no pollution.
