1. A jet pump loop reactor with injection of air bubbles, possibly of oxygen- enriched air, used for sewage oxygenation consisting of a sewage supply chamber, an air supply chamber, a chamber for contacting sewage with air, and a phase separation chamber, characterised in that it has an air injection chamber (1) closed, at the upper part, with a cover (10) with nozzles (11) mounted on it and projecting over the sewage supply chamber (2) situated over the air injection chamber (1), and the sewage supply chamber (2) is partly closed with a cover (12) in the form of a truncated cone, and the opened part of the cover is generally located on the same level as the nozzles (11) which supply the air, limiting, from the lower part, the chamber of intensive sewage circulation (3) constituting annular space between the reactor blanket and a suction and pressure pipe installed inside (7) and broadened, on the lower part, with the use of a damming up component with an intermediate pipe (8) fastened on the upper section of the suction and pressure pipe (7), such an intermediate pipe constituting, together with the blanket, the phase separation chamber (5); above the lower tip of the intermediate pipe (8) with the suction and delivery pipe (7) fastened on it in general concentrically, in the blanket, there is a pipe discharging oxygenated sewage, and above the intermediate pipe (8) there is an air drain connected to a condensation remover (9) system(6).<IMAGE>
