Waveform subsurface flow constructed wetland nitrogen and phosphorus removal device for dispersing domestic sewage of peasant households

The utility model relates to the technical field of sewage treatment, and discloses a corrugated subsurface flow constructed wetland nitrogen and phosphorus removal device for dispersing domestic sewage of peasant households, which comprises a wetland body, polyethylene impermeable membranes, a water distribution pipe and a water collection pipe, a soil layer, a warm-keeping isolation layer and a filler matrix layer are sequentially arranged in the wetland body from top to bottom, a plurality of lower inclined partition plates are arranged in the filler matrix layer, a plurality of upper inclined partition plates are arranged in the soil layer, one ends of the upper inclined partition plates extend into the filler matrix layer, and the other ends of the upper inclined partition plates extend into the filler matrix layer. According to the utility model, the oxygen content in the wetland body can be effectively increased, and the nitrogen removal capability is improved, so that the device can still be normally
