Abstract
PURPOSE: To obtain a water treating device for deep tank with which the air volume can be easily controlled with a reduction of the power consumption, by spraying the water to be treated to the upper part of a descending water path of the deep tank form an outside tank to suck up the air and sending the treated water back to said outside tank through an ascending water path.
CONSTITUTION: A pump 17 is driven with a valve 18 and a control valve 21 closed and a valve 23 opened, and the inside of an inner pipe 13 is decompressed by a vacuum pump 24. Thus the water to be treated in a descending water path 14 within the pipe 13 is raised up. Then the valve 23 is closed to stop the operation of the pump 24, and the valve 18 is opened to spray the water to be treated through an ejector nozzle 19. At the same time, the valve 21 is slowly opened to mix a proper amount of air into the water to be treated which is sprayed out of the nozzle 19. As a result, the water to be treated within the pipe 13 is flowed down into the path 14 by the difference H of the water levels. Thus the water to be treated is circulated to a tank 12 via an ascending water path 15. Meanwhile the water to be treated which discharged foams in the tank 12 is supplied to an O2 sucking room 16 provided at the upper part of the pipe 13 by a pump 17. Thus the new O2 is supplied, and at the same time the diffeence H is held.
