Abstract: This paper introduced the principle and technological superiority of sewage source heat pumps. According to the water
quality characteristics of treated sewage, the problems related to blockage, corrosion and scaling were solved by setting reasonable
pre-treatment device for sewage utilization, adding secondary circulation water circuit and backwashing filter, and selecting heat
exchanger of special material. Through the actual measurement of project case and energy efficiency evaluation of national civil
building energy efficiency evaluation agency, it was concluded that the system energy efficiency ratio was 3.61, the unit energy
efficiency ratio was 5.44, the energy efficiency of civil buildings was 65%, the energy efficiency of public buildings was 50%; SO₂
emissions reduction was 11.9 t, CO₂ emission reduction was 1 469.35 t, and annual dust emission reduction was 5.95 t compared
with other air conditioning systems; annual cost savings was 1.232 3×10⁶ yuan.
