A desulfurization apparatus includes a blowdown water line, an organic matter remover, an absorber, and a makeup water introducing line. The blowdown water line is for introducing boiler cooling tower blowdown water from a boiler cooling tower. The organic matter remover is disposed on the blowdown water line to remove organic matter in the boiler cooling tower blowdown water by activated carbon. The absorber is configured to absorb sulfur oxides in flue gas from a boiler. The makeup water introducing line is for introducing the boiler cooling tower blowdown water from which the organic matter has been removed as makeup water for the absorber.
