The invention relates to a water working medium high-temperature heat supply heat pump system for recovering waste heat. The system comprises a waste heat recovery system, a water working medium high-temperature heat supply heat pump system body and a solar auxiliary heating storage system, wherein the waste heat recovery system comprises a waste heat liquid inlet pipeline, an evaporator and a waste heat liquid return pipeline which are in fluid communication in sequence. The water working medium high-temperature heat supply heat pump system body comprises a liquid storage tank, a circulating pump, an evaporator, a water vapor compressor, a condenser and a liquid collection tank, wherein the liquid storage tank, the circulating pump and the evaporator are sequentially in fluid communication to form a first fluid circulation loop, the liquid storage tank, the water vapor compressor, the condenser and the liquid collection tank are sequentially in fluid communication to form a second fluid circulation loop, and the liquid collection tank is in fluid communication with the water vapor compressor and used for inputting condensate into the water vapor compressor. According to the invention, the liquid collection tank can automatically compensate for the water vapor compressor, and solar energy can be introduced to heat waste heat liquid when waste heat is insufficient.
