The invention discloses an efficient nitrogen and phosphorus removal anti-blocking constructed wetland system, and relates to the technical field of constructed wetland construction. The system comprises an aeration reoxygenation chamber, an enhanced carbon removal chamber, an enhanced nitrogen removal chamber, an enhanced phosphorus removal chamber, a sludge sedimentation tank and the like. A water inlet channel is mainly used for uniformly distributing water and collecting purified water. The aeration reoxygenation chamber is a main body unit for water quality purification and mainly comprises an aeration device, composite filler and plants, and when a polluted water body flows through the unit module, the water quality can be purified by virtue of the composite filler, soil filtration, and activities of aquatic plants, high-efficiency microorganisms and the like. According to the water quality of inlet water and the water quality target needing to be achieved, different concentrated and matched fillers can
