Temperature control device in seawater culture pond water backflow processing

A temperature control device in seawater culture pond water backflow processing comprises a backflow water tank, culture ponds and heat exchange pumps. The temperature control device is characterized in that a heat storage water tank and a plurality of heat exchangers are additionally installed; a water outlet of the heat storage water tank is communicated with a solar water heater through a water pump, a water outlet of the solar water heater is communicated with a water inlet of the heat storage water tank, another water outlet of the heat storage water tank is in pipeline communication with a heat source header pipe through a water source heat pump, and the heat source header pipe is in pipeline communication with a plurality of heat source branch electromagnetic valves; each backflow branch pipe is communicated with a liquid inlet of a corresponding heat exchanger, and a liquid outlet of each heat exchanger is communicated with a backflow port of each culture pond; and each heat source branch electromagne
