The invention discloses a continuous flow aerobic granular sludge reaction device provided with an inner sleeve and a continuous flow aerobic granular sludge reaction method, and belongs to the technical field of biological sewage treatment. The device comprises a water inlet unit, a reaction main body unit, a precipitation-sludge reflux unit and a water outlet unit, an inner sleeve is coaxially sleeved in a reactor main body of the reaction main body unit, an aeration device is arranged at the inner bottom, and a water inlet is formed in the lower part and is communicated with the water outlet end of a water inlet pipe; and the inner sleeve is of a vertically-closed hollow cylindrical structure, and a plurality of through holes are evenly formed in the side wall of the inner sleeve. The inner sleeve is externally connected with a power device capable of driving the inner sleeve to rotate by taking the axis as a rotating shaft, so that the inner sleeve can rotate in the reactor main body and does not interfer
