Document Type and Number:
Japanese Patent JP5765498
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a treatment method and a treatment apparatus for barren solution including hydrogen sulfide, for efficiently removing hydrogen sulfide from the barren solution.SOLUTION: The treatment method for barren solution including hydrogen sulfide uses an aeration tank that comprises: a reaction container 110 of a vertical cylindrical shape; an agitation blade 120 provided in the reaction container 110; a circular ring-shaped aeration tube 130 having a plurality of blowing-out ports 131 provided in a bottom of the reaction container 110; and a baffle plate 151. Aeration is performed in the aeration tank by spraying aeration gas into the reaction container 110 from the plurality of blowing-out ports 131 of the aeration tube 130 while agitating liquid by rotation of the agitation blade 120, and the flow of the aeration gas is straightened by the baffle plate 151.
