Abstract

PURPOSE: To enhance oxygen dissolving efficiency and total power effect by providing an ejector pump having a valve to an output side thereof and a nozzle or the like in the vicinity of a liquid surface in an aeration tank with a water depth of 10m or more so as to flow a jet stream downwardly in a vertical direction.
CONSTITUTION: The aeration tank is constituted from a cylindrical aeration tank 1 with a water depth of about 10W300m having different diameter in an upper and a lower sides thereof and a separate tank 11 housing an ejector pump 2. The main body of the ejector is present in the tank 11 different from the aeration tank 1 arranged in water in the vicinity of the liquid surface in the aeration tank 1 and a pumped liquid emitted from the ejector pump 2 having a valve 8 provided to the emitting port side thereof is injected to a vertical downward direction in the opposed side from a nozzle 4 and involves air from an air sucking pipe 5 equipped with a valve 9 of which the inlet is opened into the atmosphere and injects the same to a throat. Subsequently, the injected air is entered into a diffuser 7 and emitted into the aeration tank from a terminal emitting port.
