FIELD: liquid aeration equipment for saturation of liquid with air oxygen to provide for biological purification of sewage water in municipal and industrial water purifying constructions.
SUBSTANCE: apparatus has aeration tank with aeration unit made in the form of ejector with aeration pipe fixed at ejector outlet end and having diameter d, and sewage water feeding and discharging pipes. Branch pipe inserted into inlet part of aeration pipe is (0.5-0.2)d long and is equipped with (0.3-0.5)d high guiding protrusions formed as cylindrical spirals adapted for causing silt mixture to circulate by cavitation at G=0.01-0.05 to provide for intensive dispersion therein of bubbles of air sucked by ejector, and uniform distribution of air bubbles across section of silt mixture flow.
EFFECT: increased efficiency and stability of biochemical purification of sewage water.
