APPARATUS AND METHOD FOR SEWAGE SLUDGE TREATMENT AND ADVANCED SEWAGE TREATMENT

A sludge treatment apparatus includes an aeration tank serving to degrade microorganisms other than Bacillus sp. in sludge to produce organic matter to thereby activate Bacillus sp.; a poor aeration tank serving to reduce the activity of microorganisms in the sludge; a spore-forming tank operated under oxygen-free conditions and serving to induce the degradation and death of microorganisms remaining in the sludge while inducing the formation of spores of Bacillus sp.; a Bacillus sp.-activating reactor provided in an internal return line extending from the spore-forming tank to the aeration tank and serving to supply minerals to the sludge returned from the spore-forming tank to activate spore-type Bacillus sp.; and a sedimentation tank serving to induce the gravity sedimentation of the sludge discharged from the spore-forming tank to separate the discharged sludge into a supernatant and a concentrated sludge.
