摘要

The device for aerating sewage in biological clarification plants and reactors, comprises a pressure chamber (5), an injector nozzle (1), an air suction pipe (2), a pressure pipe (4), and a jet pipe (6), which opens in an opening (O) of the pressure chamber opposite to the air suction pipe. The suction and pressure pipes open in the pressure chamber. The air suction pipe is movable in the area of its free end and opposite to the jet pipe. The pressure chamber leaves an opening in form of the injector nozzle that is small relative to the diameter of the air suction pipe and the jet pipe. The device for aerating sewage in biological clarification plants and reactors, comprises a pressure chamber (5), an injector nozzle (1), an air suction pipe (2), a pressure pipe (4), and a jet pipe (6), which opens in an opening (O) of the pressure chamber opposite to the air suction pipe. The suction and pressure pipes open in the pressure chamber. The air suction pipe is movable in the area of its free end and opposite to the jet pipe. The pressure chamber leaves an opening in form of the injector nozzle that is small relative to the diameter of the air suction pipe and the diameter of the jet pipe. The opening of the injector nozzle is size-adjustable by moving the air suction pipe. The opening of the injector nozzle has maximum size relative to the opening (O). The air suction pipe, the jet pipe and the opening (O) are round so that the injector nozzle has an opening in form of a circular segment. The free end of the air suction pipe or the air suction pipe consists of rubber. The jet pipe is introduced into liquids and water is pressed via the pressure pipe into the pressure chamber. The jet pipe discharges in a fixed bed of the reactor so that a water-air mixture is directed in and/or below the fixed bed. The jet pipe comprises a guiding device at its free end. An independent claim is included for a procedure for aerating liquid media in purification plants and reactors using a device.
