The invention relates to a precise aeration control system for an aerobic activated sludge reactor. The precise aeration control system comprises an aeration tank and aeration components uniformly distributed in the aeration tank, the aeration component comprises a shell with a ventilation window, an impeller rotationally connected to the interior of the shell, a driving part for driving the impeller to rotate, air inducing pipes arranged in the circumferential direction of the shell at equal intervals, aeration pipes communicated with the air outlet ends of the air inducing pipes, an electric control chamber fixedly arranged at the top of the shell, an electromagnetic valve fixedly arranged at the end part of the air inlet end of the air inducing pipe, a gas flow meter fixedly arranged in the air inducing pipe, and an induced draft fan connected with the air inducing pipe. According to the aeration control system adopted by the invention, the aeration quantity required by the treatment process is calculated
