Device for simulating nitrogen and phosphorus pollutant circulation and removal mechanism under wetland lake water level change

The utility model discloses a nitrogen and phosphorus pollutant circulation and removal mechanism device under simulation of wetland lake water level change, which relates to the technical field of sewage treatment and comprises a transparent shell, a water inlet pipe, a water outlet pipe and an exhaust pipe are fixedly communicated with the surface of the transparent shell, and sampling holes and electrode holes are formed in the surface of the transparent shell. A gravel layer is laid at the bottom of the transparent shell, the upper portion of the gravel layer is filled with lakebed sediment, and a water level monitoring device is arranged on the surface of the transparent shell. The device can detect the circulation and removal mechanism of nitrogen and phosphorus pollutants under the change of water level by simulating the environmental conditions of wetland lakes, can more deeply understand the characteristics of spatial and temporal change of lake water environment, has the characteristic of no need of
