摘要

A seawater desulfurization and oxidation treatment device is provided with 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 is configured by comprising: 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 on the upstream side from the upstream side weir (21A) and mixes the acid desulfurization seawater (13) with the dilution water (14) while introducing the acid desulfurization seawater therein; and a sub flow path (20B) which supplies the dilution water (14) that is detoured from the upstream side from 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).
