Aeration equipment commonly used in sewage treatment
In the AO process wastewater treatment equipment and sewage treatment projects, aeration equipment can often have an important impact on the treatment effect. As a professional manufacturer of rural sewage treatment equipment, Kinglv pays attention to the details of sewage equipment, insists on quality above all else, and ingeniously casts fine equipment. A lot of research has been done on the aeration equipment. Different sewage treatment systems need to be properly matched with aeration equipment to achieve maximum effect. Today, Kinglv Environmental Protection will bring you to understand the more common aeration devices in sewage treatment.
Aeration equipment can generally be divided into three categories: surface aeration, blast aeration, and jet aeration. The surface aeration device, that is, the mechanical agitation aeration device, is realized by the operation of the axial flow impeller and is directly driven by the motor to spray the waste water through the conduit through the water guide plate. During the process of spraying, the water will form a thin water curtain thinly, which becomes a water droplet after being contacted by air, and when the falling water droplet collides with the liquid surface, the large amount of bubbles and turbulence generated increases the oxygen content of the water.
China's integrated sewage treatment equipment mostly uses compressed air aeration equipment, which is often referred to as a blower. Under the action of a blower, the purpose of aeration in water is achieved through a duct and a diffusion device, and the air and the liquid in the pool can be made. Produce effective contact. The blast aeration device has the advantages of convenient operation and management, simple equipment structure and automatic operation and maintenance.
The amount of water in the jet aeration device is generated by the submersible pump, which passes through the nozzle to become a high-speed water flow, and the negative pressure forms a rear intervening air around the nozzle. After the water flow and the mixed flow are mixed, the mixed flow is formed in the diffusion pipe, and Rapidly sprayed out, the water flow will be mixed with a large number of bubbles, and at the same time deeper in the water, as well as a large area of vortex stirring, to achieve the entire aeration.
