The invention relates to a zanjon air lifting pushing solid circulation inversion A<2>O integrated construction oxidation ditch, which comprises an anoxic zone, an anaerobic zone, an aerobic zone provided with a millipore aerator group and an inversion A<2>O integrated construction oxidation ditch of a solid and liquid separating zone. The solid and liquid separating zone is arranged at the frontend of a main ditch, the anaerobic zone is arranged at the tail end of the main ditch, and water inlets are respectively arranged at the front ends of the aerobic zone and the anaerobic zone. The integrated construction oxidation ditch is characterized in that a horizontal partition board which divides the main ditch into an upper groove layer and a lower groove layer is arranged at the middle-lower part of the main ditch, the aerobic zone and the anaerobic zone are respectively arranged at the upper groove layer and the lower groove layer, the aerobic zone is internally provided with n (n ismore than or equal to 1) aeration lifting zone (s) which is (are) composed of an inlet water-retaining wall, an outlet water-retaining wall and the millipore aerator group and is (are) provided with a lower water inlet and an upper water outlet, the horizontal partition board of a first grade aeration lifting zone is provided with a plurality of lifting holes, and the aerobic zone is internally divided into n aerobic reaction zone (s) corresponding to the aeration lifting zone (s).The integrated construction oxidation ditch has the advantages that: the yielding water quality, particularly thedephosphorization and denitrification effect, is better, the occupation area is reduced, the equipment is reduced, the operation is simplified, and the operation cost is lowered.
