Aeration is a method of bringing air and water into strong contact, with the purpose of dissolving oxygen in the air into the water or expelling unwanted gases and volatile substances into the air. Aeration equipment is widely used in sewage treatment for this purpose.
Aeration refers to the process of forcibly transferring oxygen from the air to the liquid, with the purpose of obtaining sufficient dissolved oxygen. In addition, the purpose of agitating the suspended matter in the tank is to prevent it from sinking and to strengthen the contact between the organic matter in the tank and the microorganisms and dissolved oxygen. This ensures that the microorganisms in the tank can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.
When using biochemical methods to treat sewage, aeration is usually the link with the highest operating cost, and aeration equipment has been constantly upgraded. Today we will talk about the advantages and disadvantages of various equipment.
