<p>PURPOSE: An apparatus for treating sewage/wastewater using air contact biomembrane and submerged biomembrane is provided, which is characterized in that air contact biomembrane and submerged biomembrane are installed to improve treatment efficiency. Also treated water is recirculated to improve treatment efficiency. CONSTITUTION: The apparatus comprises a biomembrane reactor(12) packed with an air contact biomembrane(2) and a submerged biomembrane(3); a sedimentation tank(8) for collecting treated water by the air contact biomembrane(2) and the submerged biomembrane(3); a discharge pipe(7) for discharging sludge of the sedimentation tank(8); a nozzle pipe(1) for transporting supernatant water by a circulation pump(9); and an overflow tank(6) for storing final treated water through a weir(11).</p> |
