Abstract

The present invention generally relates to an aerobic bioreactor for treating aqueous waste comprising: (a) a reservoir (2) having lower and upper portions, and opposite inflow (14) and outflow ends (16); (b) an inlet (15) located at said inflow end (14) for supplying said aqueous waste into said reservoir and an outlet (17) located at said outflow end (16) for supplying the treated aqueous waste from said reservoir; (c) at least one oxygen-containing medium diffuser (40), positioned in said lower portion of said reservoir; (d) at least one air lift pump (38) located in said lower portion of said reservoir and positioned for sucking from said lower end portion and for transporting upwardly at least in part said oxygen-containing medium and a mixed liquor comprised of said aqueous waste and of a biomass capable of biodegrading said aqueous waste; and (e) a channel system (34) positioned in said upper portion of said reservoir for receiving said mixed liquor from said air lift pump and discharging said mixed liquor in the vicinity of said inflow end (14), whereby said at least one air lift pump and said at least one oxygen-containing medium diffuser (40) enable a substantially homogeneous oxygenation of said mixed liquor within said bioreactor.
