Abstract

PURPOSE: To enable sewage to be aerated cheaply and efficiently with simple construction by using a water pump to mix sewage with air in place of a blower and by jetting the mixt. into sewage.
CONSTITUTION: Water pump 5 is set in water to be aerated. Water-delivering ejector 6 is put into gas-dispersing nozzle 3 to raise the press. of air jetted from nozzle 3. The air is fed from blower 2. The delivery air vol. of blower 2 and the jet air vol. of pump 5 are made about equal. Pump 5 may be set on land to produce good effects as well.
