The invention discloses an MBBR system for enhancing ammonia nitrogen treatment via an efficient flocculation sedimentation tank and an operation method, belonging to the technical field of water treatment. The MBBR system comprises a reaction tank, a main water inlet pipeline and a main water outlet pipeline, wherein the interior of the reaction tank is sequentially divided into a flocculation reaction zone, a sedimentation zone, an aeration reaction zone and a water outlet zone from front to back; the main water inlet pipeline is connected to a tank body of the flocculation reaction zone; the main water outlet pipeline is connected to a tank body of the water outlet zone; to-be-treated water enters from the main water inlet pipeline, sequentially passes through the flocculation reactionzone, the sedimentation zone, the aeration reaction zone and the water outlet zone, and is then discharged through the main water outlet pipeline; a sludge collecting hopper is additionally arranged in the water outlet zone t
