Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment flotation machine. Background Art
[0002] A sewage treatment flotation machine is a device that uses the principle of gas and liquid separation to treat water. It generates a large number of tiny bubbles, causing air to attach to suspended particles in the form of highly dispersed bubbles, resulting in a state with a density lower than that of water. Buoyancy causes the particles to float on the water surface, thus achieving solid-liquid separation.
