▎ 摘　　要

NOVELTY - The system has an anoxic tank (100) for removing nitrogen in wastewater introduced from an outer side. A first space portion (210) and a second space portion (220) are separated by a partition wall (201). An anaerobic tank (200) transfers supernatant water to a pressurized flotation tank (500) that is connected with a floating pumping device (221). A coagulation tank (400) injects coagulant into supernatant water introduced from the second space portion of the anaerobic tank to generate coagulated water in which phosphorus in the supernatant water is coagulated. A micro-bubble generator (501) is connected to a rear end of the coagulation tank to remove phosphorus contained in the coagulated water in a form of scum. A separation membrane (302) in the membrane separation tank is coated with polyvinylidene fluoride and graphene oxide. A positive electrode and a negative electrode in the pressure flotation tank removes nitrogen oxides and sulfur oxides. USE - Membrane bioreactor (MBR) wastewater processing system. ADVANTAGE - The device improves efficiency of solid-liquid separation by using micro-bubbles, removes contaminants clogging the separation membrane to extend the life span of the separation membrane, maximizes total phosphorus treatment efficiency, and minimizes a site area required for the process by changing a process sequence of the treatment tank. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the MBR wastewater processing system (Drawing includes non-English language text). 100Anoxic tank 200Anaerobic tank 201Partition wall 210First space portion 220Second space portion
