Abstract
PURPOSE: To provide the titled apparatus comprising a prestage treatment tank having a rotary disc with a large diameter provided at a wide interval therein and a poststage treatment tank having a rotary disc with a small diameter provided at a narrow interval wherein an oxygen shortage status is prevented by attaching microorganisms uniformly on these discs and sewage treatment is carried out efficiently.
CONSTITUTION: A sewage poured into a prestage treatment tank 3 in contacted with plural rotary discs 7 with a large diameter rotated by a rotary shaft 9 to form a gelatine like microorganism layer on the surfaces of the discs 7. Then, said sewage is treated in the treatment tank 3 and the sewage with reduced org. substances is introduced into a poststage treatment tank 4 and contacted with plural discs 8 having a diameter smaller than that of the discs 7 and provided at a narrow interval to form the microorganisms on the surfaces of the discs 8. Subsequently, the treated water in the treatment tank 4 is sent into a precipitation tank 6 provided to a lower portion of the treatment tank 4 to subject a sludge to precipitation treatment and the purified water is discharged.
