Abstract

An aeration apparatus that would realize favorable mixing of used seawater flowing through a water channel in its side-to-side width direction. There is disclosed an aeration apparatus (10A) disposed along a water channel (1) adapted for flow of the used seawater having been discharged from a desulfurization column of flue gas desulfurization equipment using seawater as an absorbent to thereby attain drainage, the aeration apparatus designed so as to generate microbubbles in the used seawater to thereby perform decarboxylation. The aeration apparatus comprises an aeration unit (20) capable of generating microbubbles from an aeration nozzle (13) attached to a header (12) in communication with an air supply pipe, the header (12) disposed on the bottom face (1a) of the water channel (1), wherein there is provided a nozzle absence section (30) forming a bottom surface area partially inhibiting the generation of microbubbles.
