ABSTRACT:
An aeration tank comprising a mixing vessel having starting and end zones. The mixing tank has water-jet aeration columns and communicates with a sludge separator provided with an outlet of recyclable sludge communicable with a circulation pump connected through a pressure pipe line to the aeration columns. There is also provided a regeneration chamber communicated with the outlet of recyclable sludge of the sludge separator and with the end zone of the mixing vessel, and a chamber for deoxygenation of the sludge medium having an inlet of waste water and communicating with the regeneration chamber and with the starting zone of the mixing vessel. A suction pipeline of the pump communicates with the chamber for deoxygeneation of the sludge medium and with the starting zone of the mixing vessel. Each aeration column has a converging inlet portion in which the pressure pipeline of the pump having a nozzle is introduced, and an adjacent portion of invariable cross-section accommodating a disperser of oxygen-containing gas. The inlet portion has ports and is provided with a gas-trapping casing immersed in the sludge medium so as to isolate the inlet portion from the outside.
