Description

Technical Field

[0001] The utility model relates to the technical field of air flotation machines, in particular to a shallow layer air flotation machine. Background Technique

[0002] The shallow layer air flotation machine mainly uses the buoyancy generated by bubbles in water to separate substances such as solid particles or grease suspended in water from the water. Specifically, the shallow layer air flotation machine usually consists of a water tank, a pump, a gas source and a sludge discharge port. Sewage is sent into the water tank by the pump and a sludge layer with a depth of several centimeters is formed in the tank. Then, a large number of tiny bubbles are injected into the bottom of the tank through the gas source. These bubbles rise to the tank surface and act on the solid particles or grease and other substances suspended in the water. Since the density of the bubbles is smaller than that of these substances, they can bring these substances to the tank surface and form a layer of foam. Finally, these foams are collected and removed, thus realizing the separation of solid and liquid.
