Abstract

PURPOSE: To purify waste water at lower cost and in a short time by removing organics adhered to bubbles formed during aeration in the form of hydrated sludge by using a specific powder in the quick aeration treatment of organics-rich waste water.
CONSTITUTION: Organics-rich waste water is subjeced to air-oxidation by continuous aeration and biological membrane oxidation repeatedly, and at the same time organics adhered to bubbles are removed in the form of hydrated sludge by spattering a powder, e.g., diatom earth or activated clay. For example, waste water is flowed from the pipe 14 into the storage tank 1 and then sent to the bubble separator 8 after being stirred in the aeration tower 5 through the flow meter 6 and the aeration tube 4. And bubbles covered with a viscous film having a high surface tension, generated in quantities on the surface of the tank 8, are scraped down to the sludge tank 26 by means of the bubble scraper 9, and then diatom earth or activated clay powder is sprayed onto the bubbles from the jet nozzle 11 by compressed air from the compressor 3 for defoaming. Then, the sludge is removed.
