The invention relates to a sewage treatment system by coupling microorganism embedding immobilization with aerobic granular sludge, which is characterized by comprising a tank body for an anaerobic zone, a tank body for an anoxic zone, a tank body for an aerobic zone, a secondary sedimentation tank and a hydraulic cyclone separator which are sequentially arranged from left to right, the tank body for the anaerobic zone is communicated with the tank body for the anoxic zone through a first pipeline, the tank body for the anoxic zone is communicated with the tank body for the aerobic zone through a second pipeline, the tank body for the aerobic zone is communicated with the secondary sedimentation tank through a third pipeline, and the side wall of the upper end of the secondary sedimentation tank is connected with a water outlet pipe through a water outlet pump. The lower end of the secondary sedimentation tank is funnel-shaped, and an outlet in the bottom of the secondary sedimentation tank is connected with
