摘要： PROBLEM TO BE SOLVED: To provide an immersed-membrane separation apparatus and a method therefor which is, even when nitrate nitrogen and nitrite nitrogen are generated in a bath with diffused air for membrane cleaning, capable of removing the nitrate nitrogen and the nitrite nitrogen within the identical bath where they are generated. SOLUTION: The immersed-membrane separation apparatus 1 comprises a membrane separation bath 10 for introducing organic waste water after a biological treatment and a membrane unit 11 immersed and disposed therein, for solid-liquid separation of the organic waste water 20 into sludge and membrane-separated waste water. The membrane unit 11 comprises a cylindrical casing 12, a membrane element 13 located above the casing 12, an opening 16 provided in the lower end of the casing 12 above the bottom surface of the membrane separation bath 10 with a gap therefrom, and a diffuser pipe 14 provided between the opening and the membrane element, forming an aerobic zone 30 at the upper part of the membrane separation bath and an anaerobic zone 31 below the membrane separation bath, thus removing the nitrate nitrogen and the nitrite nitrogen out of the anaerobic zone.
