Summary:PROBLEM TO BE SOLVED: To provide a seawater desulfurization oxidation treatment device and a seawater flue-gas desulfurization system capable of making the system compact.SOLUTION: A seawater desulfurization and oxidation treatment device includes an oxidation/aeration tank 16 for performing water quality restoration treatment on acid desulfurization seawater 13 containing sulfurous acid (HSO) generated by subjecting a sulfur oxide in exhaust gas from a boiler to seawater desulfurization, using dilution seawater 14 and air, and also includes a main flow path 20A which has an upstream-side weir 21A formed on the inlet side in the longitudinal direction of the oxidation/aeration tank 16 and into which the dilution seawater 14 is introduced, an upstream-side mixing portion 22A which is formed upstream of the upstream-side weir 21A and mixes the acid desulfurization seawater 13 with the dilution seawater 14 while introducing the acid desulfurization seawater 13, and a sub flow path 20B which supplies the dilution seawater 14 that is detoured from the upstream-side of the upstream-side mixing portion 22A of the oxidation/aeration tank 16 to post-dilute the acid desulfurization seawater 13 oxidized and aerated in the oxidation/aeration tank 16.
