Membrane coupled sequencing batch apparatus for separation

PURPOSE: Provided is a membrane coupled sequencing batch apparatus for separation. The apparatus is characterized in that hollow fiber membrane is submerged in an SBR(sequencing batch reactor) for improving separation efficiency of solid/liquid and for preventing wash-out of bacteria. CONSTITUTION: The apparatus is composed of the following parts: an SBR(2) for treating wastewater biologically; a submerged hollow fiber membrane(1) installed inside the SBR(2) for filtering contaminants; a diffuser(3) for supplying air to the hollow fiber membrane(1); a circulation pump(7) and a mixer(8) for mixing inside of the SBR(2); and a pump(6) for discharging supernatant water filtered by the hollow fiber membrane(1).
