Constructed wetland structure and system

The utility model relates to an artificial wetland structure and system. The device is suitable for the technical field of water pollution treatment. The technical problem to be solved by the utility model is to provide an artificial wetland structure and an artificial wetland system. The technical scheme adopted by the utility model is as follows: the constructed wetland structure is characterized by comprising a sewage filtering module, a water inlet and a water outlet, the sewage storage module is arranged around the outer edge of the sewage filtering module and is used for collecting sewage to be treated; the discharge tank is arranged above the sewage filtering module and is communicated with a filtering water outlet hole of the sewage filtering module; and the discharge pipe is communicated with the discharge tank and is used for discharging water in the discharge tank, so that the water level in the discharge tank is lower than that in the sewage storage module, and sewage in the sewage storage module
