The invention relates to a multi-flow-state constructed wetland sewage treatment device, and belongs to the technical field of wastewater treatment. Comprising a water distribution pool, a combined flow constructed wetland pool and a water collection and drainage pool, the combined flow constructed wetland pool comprises a vertical downstream constructed wetland pool, a vertical upstream constructed wetland pool and a horizontal flow constructed wetland pool, the water distribution pool, the combined flow constructed wetland pool and the water collection and drainage pool are sequentially connected in series and adjacently arranged from left to right, and the bottom surfaces of the water distribution pool, the combined flow constructed wetland pool and the water collection and drainage pool are located on the same horizontal plane; the heights are the same. According to the invention, three flow states are realized in one set of constructed wetland device, and pollutants such as biochemical oxygen demand, nit
