Description

Technical Field

[0001] The utility model relates to the technical field of artificial wetland oxygenation, and more specifically to an artificial wetland oxygenation device. Background Art

[0002] Artificial wetlands are swamp-like surfaces that are artificially constructed and controlled. Sewage and sludge are distributed in a controlled manner to the artificially constructed wetlands. In the process of sewage and sludge flowing in a certain direction, the sewage and sludge are treated mainly by the physical, chemical and biological synergistic effects of soil, artificial media, plants and microorganisms. During the use of artificial wetlands, since the water flows in a fixed direction on the surface or inside the soil layer, the water has less contact with the air, which makes the oxygen content inside the water body low, and there will be insufficient oxygen content.

[0003] After searching, the utility model patent with announcement number CN218868812U discloses an artificial wetland oxygenation device, including a water storage tank, a water collection cavity and a soil layer, a water storage tank is arranged at one end of the soil layer, and a water pump is installed at the bottom of the water storage tank away from one end of the soil layer, a water collection cavity is arranged inside the soil layer, and wetland planting troughs are evenly arranged on the top of the soil layer, a fixing plate is installed at one end of the top of the soil layer close to the water storage tank, and an oxygenation spray water pipe is installed at one end of the fixing plate close to the soil layer; the patent is equipped with a water pump, a water outlet connecting pipe, an oxygenation spray water pipe and a nozzle. During use, the water pump draws out the water inside the water storage tank, so that the water is evenly sprayed through the nozzle, so that the water can fully contact with the air, thereby increasing the oxygen content in the water body and avoiding the situation of low oxygen content.

[0004] However, the above patents still have the following shortcomings: the area of ​​artificial wetlands is generally large, and the positions of the oxygenation spray water pipes and nozzles are fixed, which is not convenient for large-scale oxygenation; in addition, the contact time between the water mist sprayed by the nozzle and the air is relatively short, and the oxygenation effect is poor. For this reason, we propose an artificial wetland oxygenation device. Utility Model Content
