In a wastewater treatment process, wastewater passes through an aerobic biological oxidation zone (12) for oxidizing BOD and converting ammonia nitrogen to nitrate. The effluent is passed to an aerobic mixing zone (16) and mixed with effluent from an anaerobic/anoxic zone (20) receiving sludge from a settling zone (24). Alternatively, an anoxic and/or anaerobic zone may be provided between the oxidation zone and aerobic mixing zone for receiving sludge, fermented sludge, or effluent from the anaerobic/anoxic zone for phosphorous removal.

Dans un système de traitement d'eaux usées, les eaux usées passent par une zone (12) d'oxydation biologique aérobie pour oxyder la DBO et convertir l'azote ammoniacal en nitrate. L'effluent passe ensuite dans une zone (16) d'agitation aérobie et il est mélangé avec l'effluent d'une zone (20) anaérobie/anoxique recevant des boues d'une zone de décantation (24). Dans une variante, on peut prévoir une zone anoxique et/ou anaérobie entre la zone d'oxydation et la zone de mélange aérobie pour recevoir des boues, des boues fermentées ou l'effluent de la zone anaérobie/anoxique, pour assurer une élimination du phosphore.
