Abstract: PURPOSE: A wastewater treatment method is provided to treat livestock wastewater promptly and environment friendly compared with existing treatment method by mixing physical treatment method using filtering membrane and biological treatment method. CONSTITUTION: The method for efficiently treating nitrogen in livestock wastewater comprises first treatment process primarily treating wastewater by removing solid from livestock wastewater flown in through an excrement purifier(1) in a centrifugal solid-liquid separator(2) and sending the solid removed livestock wastewater to a membrane system(4) so that the livestock wastewater flows in a flow rate of 0.5 to 1 ton/day; and second treatment process of secondly treating the wastewater by storing the solution treated in the first treatment process in a holding tank(3) so that the treated solution is sent to an Anammox process(5) or 30 to 50% of the treated solution is recirculated and sending the first treated solution rotationally coming out to a fluidized bed reactor(6) in a flow rate of 30 to 50 L/day.
