Description

Technical Field

[0001] The invention relates to the technical field of aeration heads, in particular to a polystyrene microporous aeration head. Background Art

[0002] Aeration is a means of bringing air and water into strong contact. Its purpose is to dissolve oxygen in the air into water, or to expel unwanted gases, suspended solids and volatile substances in water into the air and the water surface. In other words, it is a means of promoting material exchange between gas and liquid. It also has other important functions, such as mixing and stirring. Oxygen in the air is transferred to water through aeration, and oxygen is transferred from the gas phase to the liquid phase by mass transfer. The most widely used theory of mass transfer diffusion is the double membrane theory proposed by Lewis and Whitman.
