Abstract
PURPOSE: To provide a sludge control device for purification tank which controls the sludge concn. in an aeration tank by decreasing the amount of activated sludge in the purification tank.
CONSTITUTION: The sewage in an aeration tank C is sucked and is sprayed through a sewage supply nozzle 3 to the inside circumferential surface of a rotary dehydration drum 2. The sewage is centrifugally separated, and the sludge deposits on the inside circumferential surface of the drum. The light water content flows through the dehydrating hole 5 on the central side of the drum then through the discharge path 33 on the outer side of the drum 2, is conducted into the dropping port 28 provided in the bottom part 6 and is returned to the aeration tank C through a return pipe 29. The deposited sludge 8 is scraped off by scraper vanes 9 and is dropped into a sludge housing box 10 provided below the sludge discharge hole 7 of the drum 2.
