Sewage heat recovery has got more and more attention. The development of sewage source heat pump technology is important for building energy-saving and consumption reduction. The working principle,characteristics and classification of sewage source heat pump technology as well as the system design were introduced. The development of new heat exchangers,latest progress in technologies of anti-clogging,scale control and anticorrosion were reviewed. The bottleneck for the widespread application of sewage water source heat pump technology was pointed out. The source separation of domestic sewage in residential areas,recovery and reuse of waste heat from grey water( bath and washing sewage)are a prospective developing trend of sewage source heat pump system in future.
