<p>PURPOSE: A wastewater treatment facility is provided to drastically cut production costs due to volume compactification and to efficiently remove bubbles drifting on the wastewater surface. CONSTITUTION: A wastewater treatment facility includes a bubble capture member (100), a coupling hose (300), a venturi tube (500), and a water pump (400). The bubble capture member is disposed near the wastewater surface stored in an aeration tank (10). The coupling hose is coupled with the bubble capture member by a pipe and absorbs air from the outside. The venturi tube is arranged in the lower part of the coupling hose to be connected to the lower part of the coupling hose and discharges fluid in the lower part of the aeration tank. An underwater pump absorbs and sends wastewater in the aeration tank to the inside of the venturi tube.</p> |
