PROBLEM TO BE SOLVED: To provide an aerobic biological treatment method in which oxygen supply speed of an oxygen dissolving membrane can be kept high by preventing adhesion of organism to the oxygen dissolving membrane.SOLUTION: The aerobic biological treatment method is provided in which oxygen is dissolved in water to be treated in a reaction tank 3 through an oxygen dissolving membrane module 32 disposed within the reaction tank 3 and the water to be treated is subjected to aerobic biological treatment. In the aerobic biological treatment method, adhesion of organisms to the oxygen dissolving membrane module 32 is prevented by suspending or flowing an organism-adhering carrier in the reaction tank 3.SELECTED DRAWING: Figure 1 【課題】酸素溶解膜に生物が付着することを防止することによって、酸素溶解膜の酸素供給速度を高く保つことができる好気性生物処理方法を提供する。【解決手段】反応槽３内に配置された酸素溶解膜モジュール３２によって酸素を該反応槽３内の被処理水に溶解させ、被処理水を好気性生物処理する好気性生物処理方法において、該反応槽３中に生物付着担体を懸濁又は流動させることにより酸素溶解膜モジュール３２への生物の付着を防止することを特徴とする好気性生物処理方法。【選択図】図１
