AERATION APPARATUS, SEAWATER FLUE GAS DESULFURIZATION APPARATUS INCLUDING THE SAME, AND METHOD FOR OPERATING AERATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an aeration apparatus capable of removing deposited materials occurring on a slit of a diffuser membrane; and to provide a seawater flue gas desulfurization apparatus including the same, and a method for operating the aeration apparatus.

SOLUTION: The aeration apparatus is immersed in diluted used seawater (not shown) which is water to be treated and generates fine air bubbles in the diluted used seawater. The aeration apparatus includes: an air supply line L5for supplying air 122 through blowers 121A to 121D serving as a discharge unit; aeration nozzles 123, each of which includes a diffuser membrane 11 having slits and to which air containing moisture is supplied; and a control unit for performing control to temporarily stop the supply of the air 122 at predetermined intervals.
