A flue gas desulfurization according to the present invention includes a desulfurization absorber that removes SOx and dust contained in flue gas, spray pipes that are provided in the desulfurization absorber, an absorbent feeding means that feeds an absorbing-agent-slurry containing absorbent, in which limestone is used as an absorbing agent, into the desulfurization absorber, nozzles that are provided in the spray pipe to spray the absorbent into the desulfurization absorber, an alkaline-agent feeding means that feeds an alkaline-agent containing solution into the desulfurization absorber, and an waste-water discharge pipe for discharging filtrate obtained by solid-liquid separating the absorbent discharged from the desulfurization absorber as waste water. A feed amount of the alkaline-agent containing solution into the desulfurization absorber is adjusted based on a discharge amount of the waste water.
