To provide a biological activated carbon treatment device capable of treating organic waste water of a high concentration at a high load, without peeling of attached organisms and by supplying a large amount of oxygen.SOLUTION: Oxygen permeable membrane modules 2a to 2c are arranged in a multi-stage in a reaction tank 3. Oxygen-containing gas from a blower B is distributed in the oxygen permeable membrane modules 2a to 2c sequentially through pipes 8,9,10, to be discharged out of a pipe 11. A fluidized bed F of an organism carrier such as activated carbon or the like is formed in the reaction tank 3.SELECTED DRAWING: Figure 1 【課題】付着生物を剥離させることなく、かつ多量の酸素を供給することによって、高濃度の有機性排水を高負荷で処理することができる活性炭生物処理装置を提供する。【解決手段】反応槽３内に酸素透過膜モジュール２ａ〜２ｃが多段に設置され、ブロアＢからの酸素含有ガスが配管４，５，６を介して酸素透過膜モジュール２ａ〜２ｃに順次に流通され、配管１１から排出される。反応槽３内に活性炭等の生物担体の流動床Ｆが形成される。【選択図】図１
