Description

Technical Field

[0001] The utility model relates to the technical field of wastewater purification, in particular to an air flotation device. Background Art

[0002] A flotation device is a water treatment device that introduces air into water in the form of tiny bubbles. These tiny bubbles adhere to particles suspended in the water, forming a three-phase mixture of water, air, and particles. When particles adhere to the bubbles, their density decreases compared to water, causing them to float to the surface, forming a scum layer that is then separated from the water.

[0003] For example, Chinese utility model patent CN220887089U discloses a flotation filtration and slag removal device, wherein the liquid inlet end of the pressure pump is connected to a wastewater inlet pipe; the liquid outlet end of the pressure pump is connected to a first delivery pipe; and the first delivery pipe extends into the pressure dissolved air tank.

[0004] However, it still has the following disadvantages: when dealing with wastewater of the same nature during the scum treatment process, bubbles of only one volume may not be able to effectively lift the scum.
