Claims

[Scope of utility model registration request]

It consists of a pump and an ejector that is fluidly connected to the discharge port of the pump in a tank containing the liquid to be treated, and that the ejector surrounds a nozzle to which the liquid from the pump is supplied and the nozzle. A nozzle body comprising an air chamber having an air introduction pipe for introducing gas, and a diffuser through which liquid ejected from the nozzle passes. An aeration device equipped with a liquid feed port that sends the liquid to be treated outside the tank between the discharge ports. .
