<p>PURPOSE:To curtail necessary power while enhancing the efficiency of circulation, by concomitantly forming circulatory substreams of different velocities and directions in bubble-mixed circulatory laminar flow caused by a main circulatory stream inside a purification tank to diffuse the stream of bubble-mixed water throughout the interior of said purification tank. CONSTITUTION:The apparatus is provided on the inner bottom of a purification tank 14, a velocity is properly changed by a reduction gear 5 while driving an electric motor 4 to rotate a propeller 6 for circulation of sludge and a plate 7 for crushing bubbles, and air supplied through an air supply pipe 9 to an air chamber 8 is introduced through an introducing hole 12 to the bottom of a conduit line A. A part of a main circulatory stream comes into collision with divergence plates 3, 3 to impede its straightness, so that small jet streams are concomitantly formed toward the outside from water-driving ducts 2 because of the pressure of the interior and merged into the main circulatory sludge stream outside the conduit line A. Hence, local eddies are formed throughout the interior of the tank by the difference of velocities and the collision of the jet streams of different directions at these parts.</p> |
