<p>PROBLEM TO BE SOLVED: To more efficiently purify a sewage with a small-scale equipment, to provide a method for economically purifying the sewage with a low energy and to develop its device. SOLUTION: A different-diameter passage consisting of a sewage inlet passage 12, a rotor 13 rotating vertically to a flow, an intermediate passage 15 with the cross-sectional area made much smaller than that of the inlet passage 12 by providing a slight clearance between the rotor and the device wall 14 and an outlet passage 16 for receiving the water from the intermediate passage 15 having A larger cross-sectional area than the intermediate passage is formed at a part of a sewage purifying pipeline, and a gas passage for ejecting a gas as the bubble by a compressor pump is connected to the front of the different- diameter passage to constitute the device.</p> |
