<p>PURPOSE: A device for discharging in sequencing batch reactor is provided, which is characterized in that a tank floats on the surface of the wastewater which is treated biologically. CONSTITUTION: A method is composed of a tank(10) which can float on the wastewater, a guiding pipe(90-1), a supporting frame(30), a cylinder(40) using oil pressure, and a pump(50). The tank made of FRP has a pipe(150) in shape of cylinder, which has a lot of holes(20) for flowing wastewater. Wastewater is settled in the reactor, and sludge layer is produced. Scum layer is floated on the surface of the wastewater. After a steady state, the pump(50) is operated to expand the cylinder(40), so the hole(20) is opened. Then, treated water is discharged through flexible hose(70).</p> |
