PURPOSE:To enhance power for agitating filthy water in a tank, by attaching horizontally or slightly downwards one or more main ejector bodies to one main ejector pipe at right angle to the main ejector pipe in a manner such that the ejectors are arranged in parallel with each other. CONSTITUTION:A main ejector pipe 1 is provided inside an aeration tank 2, and water 3 sent through an aerating pump is supplied through a flexible tube 4 and a receiving opening 5 into the pipe 1. Main ejector bodies 6 and suction pipes 7 equipped with openings at the jet parts of said main ejector bodies 6 are attached to the main ejector pipe 1. The lower end of a guide rail 8 is fixed onto the bottom of the tank 2, while the upper end is fixed to the upper wall surface of the tank 2. In addition, elevators 11 are provided at the uppermost ends. Two movable supporting stands 9 at the right and left sides support the main ejector pipe 1 and vertically move at the same time. Rotating or sliding pieces 10 are engaged with the guide of the guide rail 8 to make the elevating motion of the movable supporting stands 9 smooth.
