DEVICE OF TREATING SEWAGE SLUDGE, AND METHOD OF TREATING SEWAGE SLUDGE
To provide a device of treating sewage sludge and a method of treating sewage sludge, capable of decreasing power consumption and an amount of ozone gas used.SOLUTION: A device 100 of treating sewage sludge, comprises: a biological treatment tank 1 that carries out a biological treatment; a settling tank 2 that is disposed downstream of the biological treatment tank 1 to separate sewage sludge into treated water and activated sludge 3; an acid treatment tank 6 that is equipped with an acid feeder 7 for feeding an inorganic acid to surplus sludge 4 which is a portion of the activated sludge 3 and an agitator 8; and an ozone treatment tank 5 that stores acid-treated sludge and reforms the acid-treated sludge with ozone gas sent from an ozone generator 11.SELECTED DRAWING: Figure 1
【課題】使用電力量とオゾンガス使用量を低減する下水汚泥処理装置および下水汚泥処理方法を提供する。【解決手段】生物処理を行う生物処理槽１と、生物処理槽１の後段で、処理水と活性汚泥３とに分離する沈殿槽２と、活性汚泥３の一部の余剰汚泥４に無機酸を添加する酸添加装置７と攪拌機８が設けられた酸処理槽６と、酸処理汚泥を貯留するとともに、酸処理汚泥を、オゾン発生器１１から送出されるオゾンガスで改質するオゾン処理槽５とを備えた下水汚泥処理装置１００。【選択図】図１
