The height ratio and diameter ratio of the front-section ASBR reactor to the rear-section ASBR reactor are 2-3. A gas outlet and a trace element adding port are formed in the top end of each of the front-section ASBR reactor and the rear-section ASBR reactor. A water inlet and a water outlet are respectively formed in the bottom side of each of the front-section ASBR reactor and the rear-section ASBR reactor. The bottom center of each of the front-section ASBR reactor and the rear-section ASBR reactor is provided with a gas circulation inlet and an aeration head, and the gas circulation inlet is arranged below the aeration head. An emptying valve and a mud discharging valve are further arranged at the bottom of each of the front-section ASBR reactor and the rear-section ASBR reactor. By the device, high-concentration organic matter can be degraded under an anaerobic condition while ammonia and nitrogen in sewage can be removed, sewage treatment efficiency is increased evidently, and treatment cost is lowered.
