Abstract

PURPOSE:To remarkably miniaturize the title device by providing an anaerobic treating part at the lower part of a waste water treating tank and an aerobic treating part at the upper part, and allowing both parts to communicate with each other through a solid-liq. separation part. CONSTITUTION:Raw water is introduced into the anaerobic treating part 43 at the lower part of the waste water treating tank 41 by a raw water supply pipe 69, then passed through the solid-liq. separation part 56 wherein solid is separated from liq., and introduced into the aerobic treating part 51 at the upper part of the tank 41. Meanwhile, a part of the treated liq. from the aerobic treating part 51 is passed through a filter medium part 55, and circulated to the anaerobic treating part 43. Another part is filtered by a filtration part 61, and then discharged to the outside of the tank 41 from a discharge pipe 81. The ammonia in the raw water is oxidized by the aerobes in the aerobic treating part 51 into nitric acid, and the nitric acid is reduced into gaseous nitrogen by the anaerobes in the anaerobic treating part 43.
