More Information
Summary:The invention discloses a constructed wetland tail water treatment system with controllable wettability- and switchable drying and sprinkling irrigation. The system can be switched into a wettability-controllable constructed wetland, a drying constructed wetland and a foliage sprinkling irrigation wetland according to needs. After the wettability-controllable wetland passes through a porous waterdistribution lattice wall and a wetland substrate layer, water is discharged from a water outlet pipe, and the liquid level of the device is controlled as required; when the constructed wetland is switched into a dry constructed wetland, water enters through the perforated water distribution pipe, flows downwards to a wetland main body, is emptied after submerging time, and enters again after idletime; when the wetland is switched into the sprinkling irrigation type wetland, water is fed through a water distribution pipe additionally provided with a nozzle for sprinkling irrigation; when themulti-stage wetland is oper
