The invention discloses novel grey green coupling integrated equipment which comprises an anaerobic tank, an aerobic tank I, an anoxic tank, an aerobic tank II, a sedimentation tank and an artificial wetland. The equipment is cylindrical, each process section is annularly arranged, and the anaerobic tank, the aerobic tank I, the anoxic tank and the aerobic tank II are positioned on the outermost layer and are sequentially connected; the middle layer is a sedimentation tank, the inner wall and the outer wall are square, perforated sludge discharge pipes can be conveniently arranged, and the inner layer is an artificial wetland. The method has the beneficial effects that energy is saved, a two-stage AO process is adopted, nitration liquid backflow and sludge backflow are not needed, the operation cost is low, and the method is economical and efficient. Equipment such as a reflux pump and an equipment room is reduced, so that the investment cost is lower, and the equipment is more economical and practical. And d
