To provide a sewage treatment system that comprises a microorganism material production apparatus that treats returned sludge or the like and produces a microorganism material that works actively in a biological reaction tank, increases the amount of organic matter treated in the sewage, and improves the precipitability of flock.SOLUTION: A sewage treatment system comprises: a microorganism material production apparatus for producing microorganism materials containing spores of specific gram-positive aerobic microorganisms by subjecting moisture-controlled sludge obtained from sewage discharged from households, factories, businesses, etc. to aerobic fermentation, wherein the aerobic fermentation is conducted at a temperature of 60°C to 110°C with oxygen supplied by gram-positive aerobic microorganisms to decompose and kill gram-negative anaerobic and passive anaerobic microorganisms; a microorganism material activation apparatus for converting the microorganism materials into active microorganism materials through germination of the spores contained in the microorganism materials; and an active microorganism material feeder for supplying the active microorganism materials to the first half of a biological treatment tank and maintaining the MLSS of at least a part of the sewage in the tank at 2,000 mg/L to 4,000 mg/L.SELECTED DRAWING: Figure 1
【課題】返送汚泥等を処理し、生物反応槽で有効に作用する微生物資材を製造する微生物資材製造装置を備え、下水中の有機物の処理量を増大させるともに、フロックの沈殿性を良好にした下水処理システムの提供。【解決手段】本発明の下水処理システムは、家庭や工場・企業などから排出される下水から得られる水分調整汚泥を、温度６０℃〜１１０℃で、酸素を供給して、グラム陽性の好気性微生物により好気性発酵させ、グラム陰性の嫌気性および通性嫌気性微生物を分解死滅させ、特定のグラム陽性の好気性微生物の芽胞を含有する微生物資材を製造する微生物資材製造装置を有し、さらに微生物資材から、微生物資材中の芽胞を発芽させた活性微生物資材とする微生物資材活性化装置、およびこの活性微生物資材を、生物処理槽の前半部に供給し、槽内の下水の少なくとも一部のＭＬＳＳを、２０００ｍｇ／Ｌ〜４０００ｍｇ／Ｌに維持する活性微生物資材供給装置を備える。【選択図】図１
