Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an air flotation device for wastewater treatment with a deodorizing structure. Background Art

[0002] The flotation device for wastewater treatment mainly produces a large number of fine bubbles in the water, causing them to adhere to solid or liquid particles in the wastewater with a density close to that of water, resulting in an overall density less than that of water. Then, the complex of these bubbles and pollutants rises to the water surface by buoyancy, thereby achieving the purpose of solid-liquid or liquid-liquid separation.

[0003] A flotation device for wastewater treatment disclosed in the Chinese utility model patent application disclosure CN220618514U has a synchronously moving bubble discharge and secondary dispersion mechanism that can rotate with the rotating control frame when in use, and the bubble discharge end can also move left and right, so that the flotation treatment is more sufficient and uniform. At the same time, after the bubbles are discharged, there is also a synchronously moving dispersion agitator on the top to stir and break the discharged bubbles, making the bubbles smaller, thereby further improving the flotation effect. It is simple to use, novel in structure, good in flotation effect, and high in practical value. However, the existing flotation device is prone to produce unpleasant odors during processing, resulting in an uncomfortable working environment. Utility Model Content
