Application of Aerating machine from China manufacturer in sewage treatment

　　Aerating machine from China manufacturer Aeration principle: Aeration is a method of making air and water in close contact with each other. The purpose of aeration is to dissolve oxygen in water or to discharge unwanted gases and volatile substances into the air. In other words, it is a means of facilitating the exchange of substances between gases and liquids. It also has other important functions like stirring and stirring.

　　Aerating machine from China manufacturer The oxygen in the air is converted into water by aeration, and the oxygen is converted from the gas phase to the liquid phase for mass transfer. This mass transfer diffusion theory is a widely used theory, which was proposed by Lewis and Whitman Double membrane theory. This is exactly the case for aeration and stirring. The specific methods are: reduce the size of the bubbles, increase the number of bubbles, increase the turbulence of the liquid, increase the installation depth of the aerator, and prolong the contact time between the bubbles and the liquid. On this basis, aeration equipment has been widely used in sewage treatment.

　　Aerating machine from China manufacturer Blast aeration is a method of introducing air bubbles into the water through a diffuser plate or diffuser tube. This method is generally used for wastewater treatment of ethylene plants. Mechanical ventilation refers to the introduction of air bubbles through instruments such as impellers.

　　Aerating machine from China manufacturer The equipment should meet the following three functions: (1) generate and maintain effective air-water contact, and maintain a certain concentration of dissolved oxygen in water under the condition that biological oxidation continuously consumes oxygen; (2) in the aeration area Generate sufficient mixing and water circulation flow; (3) maintain sufficient liquid velocity to keep living solids in suspension.
