<p>PURPOSE:To positively supply a large amount of oxygen into seawater by arranging a large number of wave removing bodies each equipped with a gas sump having recessed parts opened downwardly in a bank body in a multistage fashion and arranging an air or oxygen jet body to the bottom part in the bank body. CONSTITUTION:The air A from air jet orifices 3A is accumulated in the recessed parts 2A of the wave removing bodies 2 each equipped with an air sump of the lowermost stage and the air A overflowing therefrom or the air A not caught by the wave removing bodies 2 each equipped with the air sump of the lowermost stage is accumulated in the wave removing bodies 2 each equipped with the air sump of the next upper stage and further accumulated in the wave removing bodies 2 each equipped with the air sump of the further upper stage and air is accumulated in the respective wave removing bodies 2 each equipped with the air sump arranged in the bank body and, as a result, many water surfaces are formed in the submerged recessed parts 2A to form such a state that oxygen in air A is easily dissolved in seawater. By this method, a large amount of oxygen can be dissolved in seawater and the amount of dissolved oxygen in seawater can be positively increased.</p> |
