Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to an aerator used for air flotation. Background Art
[0002] An air flotation aerator is a type of aeration equipment used in water treatment processes, primarily in the flotation process. It injects air into water, forming tiny bubbles. These bubbles attach to solid particles suspended in the water, causing them to float to the surface and be more easily separated from the water. This process, known as flotation, is a common method for treating suspended solids in industrial and municipal wastewater.
[0003] In the existing turbine aerator, the air inlet at the upper end of the hollow rotating shaft is exposed to the air for a long time during use. Due to the environment, on the one hand, suspended matter, sediment or other particulate matter in the sewage will block the air inlet along with the air. On the other hand, after long-term operation, microorganisms will form a biofilm around the air inlet, which will also affect the entry of sewage into the bottom through the air inlet. Therefore, it is necessary to provide an aerator for flotation to solve the above problems. Utility Model Content
