<p>PURPOSE:To enhance treatment capacity and to arbitrarily set the cross-sectional area of a water channel, by forming a flow inhibiting wall to a water channel so as to traverse said water channel and forming a communication passage to said flow inhibiting wall in a horizontal state so as to communicate the upstream side and the downstream side of said flow inhibiting wall. CONSTITUTION:When a motor 24 is driven to rotate an impeller 25 and air is emitted from the air diffusion perforations 42 of an air chamber 42, the liquid mixture in the upstream side of a flow inhibiting wall 5 is flowed into a communication pipe 12 from an inflow cone 23 to enter between the air chamber 41 and a water guide cover 44 through said pipe 12 and sent to the downstream side of the flow inhibiting wall 5 under pressure in a state mixed with air bubbles while the liquid mixture in the water channel 1 flows and recirculates to a counterclockwise direction along the water channel 1. Because the communication pipe 12 is horizontal and the inflow direction of the liquid mixture is horizontal, vortex streams are generated to the liquid surface of the liquid mixture in the same way as such as a case that the liquid mixture is flowed in from above and it is unnecessary to mix air bubbles into the part of the impeller 25 from the liquid surface.</p> |
