Abstract
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 operated, a plurality of wetlands in the multi-stage wetland can be connected in series; according to the sewage treatment system, multiple operation modes are integrated into one device, so that the function of switching multiple wetland types and operation modes is realized, and the adaptability to sewage treatment and the resource utilization of wetlands are improved.
Description
technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a controllable wetland tail water treatment system of a constructed wetland with switchable sprinkler irrigation. Background technique [0002] Constructed wetlands are different from natural wetland systems. They are a kind of sewage collection and treatment system artificially constructed to simulate natural wetland systems. Constructed wetlands are mainly composed of substrates, plants, microorganisms and water bodies. Through species symbiosis and material circulation, environmental pollution can be reduced, and sewage can be treated and recycled. Compared with the traditional sewage treatment system, the artificial wetland has the advantages of large buffer capacity, better treatment effect, saving investment, and convenient operation and maintenance; at the same time, selecting suitable wetland plants according to the local ecological environment and geographical...
