Abstract

Provided is an apparatus for processing sewage by granulating activated sludge and a method thereof. The sewage processing apparatus includes an anaerobic granulation tank for granulating suspended microorganisms; an indirect aeration tank for supplying oxygen to the supernatant transported through a first transport pipe; an aerobic granulation tank for granulating suspended microorganisms; and a discharge pipe for discharging supernatant of finished water obtained after circulating a series of the anaerobic granulation tank, the first transport pipe, the indirect aeration tank, the aerobic granulation tank repeatedly.
