<p>PURPOSE:To efficiently dissolve fine bubbles in a liquid, by arranging a rotary body provided inside an aeration tank in a manner such that the opened side of its drum part is directed downwards to dip a notched part or a hole, an outer blade part and an inner blade part in the liquid. CONSTITUTION:A motor 8 is rotated so as to dip a rotary body 1 in a liquid down to the middle parts of blade parts 4, 5. By rotating said rotary body 1 about its vertical axis as a center, the dent inner part 9 of the rotary body 1 opened downwards comes to negative pressure against the outside. Hence, air flows into said inner part 9 from the outside. Hereon, a notched part 3 cuts a stream of air and a stream of water scattered outwards from the center of the rotation, so that these streams are mixedly brought into contact with each other to efficiently dissolve fine bubbles in the liquid. That is, the circulation of air is brought about by the rotary body 1, and the gas-liquid contact is accelerated by the notched part 3.</p> |
