The invention the surface of the water bubbles on from the air aeration in the aerobic atmosphere of the waste water was then sucked by the suction power of the pump discharge back to the aerobic tank bottom to re-introducing the foam into the aerobic tank by deuldorok soluble in water, in the package the process of foam improved so as to minimize the odor generated waste water processing method and relates to the processing unit.
Wastewater treatment process of the invention, while gradually conveying the flowing step, and the influent to enter and store the waste water in the influent tank flow rate control step by step in a plurality of aerobic tank having respective diffusers decomposing organic blowing air in each of the aerobic tank sucking the exhalation phase and the surface of the water bubbles on generated by air aeration in the aerobic step to the suction force of the pump end of the treatment fermentation through the bubble inlet; and the bubble inflow step of re-discharged to the lower portion of each of the aerobic tank It consists of the process steps for processing in the processing tank.
