PURPOSE:To mix fine air particles into the water over a wide range by generating a spiral water flow by the impeller of a water flow generator, and supplying compressed air to the central part of the water flow in the same direction as the water flow. CONSTITUTION:The spiral water flow JF is generated by the impeller 2 of the water flow generator 1, and compressed air is supplied from a compressed air source 13 such as a blower to the central part of the water flow in the same direction as the water flow through an air supply pipe 11, an air chamber 10, a communicating pipe 12, etc. As a result, an air flow AF is generated in the water flow, the air in the central air flow is swallowed up by the wave JFW of the spiral water flow JF, and the air is mixed into water over a long distance as fine particles. |
