Provided is a hot-water supply temperature control structure for a waste heat recovery system using a mixing valve, wherein the hot-water supply temperature control structure comprises: a hot-water tank including a waste heat exchanger which generates hot water by recovering waste heat from a waste heat source, a heating heat exchanger in which heat is exchanged to provide heating using the hot water, and a temperature sensor which checks the temperature of the hot water, and storing the hot water which exchanges the heat in the waste heat exchanger; a boiler heating the hot water, which exchanges the heat in the hot-water tank, to satisfy a heating and a hot-water supply predetermined temperature predetermined by a user, and supplying the heated hot water to a heating space and a hot-water supply space; the mixing valve installed on a hot-water line connected from the hot-water tank to the boiler, and capable of supplying a mixture of direct water and the hot water, which flows from the hot-water tank, to the boiler after mixing the direct water with the hot water; and a control part controlling the mixing valve after determining the amount of the direct water to be mixed with the hot water flowing in the hot-water line when temperature in the hot-water tank is detected to be as much as 0 to 10°C lower than the hot-water supply predetermined temperature of the boiler by the temperature sensor.
