Abstract:
(EN) The inside of a treatment tank 2 is divided by dividing members 3 - 6 into a membrane separation area 11, first and second anaerobic areas 12, 13, and first and second aerobic areas 14, 15. A membrane separation device 27 provided with an air diffuser 31 on the lower side thereof is disposed in the membrane separation area 11. Activated sludge passing through the membrane separation device 27 by means of the ascending flow of diffused air from the air diffuser 31 branches from the membrane separation area 11 and flows into the first and second anaerobic areas 12, 13. Part of the activated sludge passing through the first anaerobic area 12 and part of the activated sludge passing through the second anaerobic area 13 flow into the first aerobic area 14, and the remainder of the activated sludge passing through the first anaerobic area 12 and the remainder of the activated sludge passing through the second anaerobic area 13 flow into the second aerobic area 15. The activated sludge of the first aerobic area 14 and the activated sludge of the second aerobic area 15 flow into the membrane separation area 11.
(FR) L'intérieur d'un réservoir de traitement 2 est divisé par des éléments de séparation 3 à 6 en une zone de séparation membranaire 11, des première et seconde zones anaérobies 12, 13, et des première et seconde zones aérobies 14, 15. Un dispositif de séparation membranaire 27 muni d'un diffuseur d'air 31 sur sa face inférieure est disposé dans la zone de séparation membranaire 11. Une boue activée traversant le dispositif de séparation membranaire 27 sous l'effet d'un flux ascendant d'air diffusé en provenance du diffuseur d'air 31 bifurque depuis la zone de séparation membranaire 11 pour rejoindre les première et seconde zones anaérobies 12, 13. Une partie de la boue activée traversant la première zone anaérobie 12 et une partie de la boue activée traversant la seconde zone anaérobie 13 rejoignent la première zone aérobie 14, tandis que le reste de la boue activée traversant la première zone anaérobie 12 et le reste de la boue activée traversant la seconde zone anaérobie 13 rejoignent la seconde zone aérobie 15. La boue activée de la première zone aérobie 14 et la boue activée de la seconde zone aérobie 15 rejoignent la zone de séparation membranaire 11.
(JA) 処理槽2内が仕切部材3~6によって膜分離区域11と第1および第2無酸素区域12,13と第1および第2好気区域14,15とに仕切られ、膜分離区域11には、下部に散気装置31を備えた膜分離装置27が配置され、散気装置31の散気により上向流として膜分離装置27内を通過した活性汚泥が膜分離区域11から分岐して第1および第2無酸素区域12,13に流れ込み、第1無酸素区域12を通過した活性汚泥の一部と第2無酸素区域13を通過した活性汚泥の一部が第1好気区域14に流れ込み、第1無酸素区域12を通過した活性汚泥の残部と第2無酸素区域13を通過した活性汚泥の残部が第2好気区域15に流れ込み、第1好気区域14の活性汚泥と第2好気区域15の活性汚泥が膜分離区域11に流れ込む。
