Description

Technical Field

[0001] The utility model relates to the technical field of aeration systems, in particular to a micro-nano aeration system for sewage treatment. Background Art

[0002] In the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool contacts with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, prevent suspended objects in the pool from sinking, strengthen the contact between organic matter and microorganisms and dissolved oxygen in the pool, and oxidize and decompose the organic matter in the sewage. This process of forced oxygenation in sewage is called aeration, among which surface aeration equipment is widely used. The working principle is to use a motor to directly drive the axial flow impeller. The sewage is sprayed from the conduit through the water guide plate to the surroundings to form a thin sheet (or water droplet) water curtain, which contacts with the air during flight to form water droplets. When falling, it hits the liquid surface, which produces turbulence and a large number of bubbles, increasing the oxygen content in the water.

[0003] After searching, a Chinese patent with publication number CN214880591U discloses a nano-micro bubble aeration device for sewage treatment systems. Under the action of a gas-liquid separation tank, large bubbles are separated and reused. The bubbles in the mixed liquid can reach micro-nano. The smaller the bubbles, the slower the floating speed, and the higher the dissolved oxygen efficiency in water. It is used in sewage treatment processes such as aeration tanks or regulating tanks, and the sewage treatment effect is significant.

[0004] However, this device cannot make aeration more thorough during the aeration process, which can easily result in a smaller contact area between microorganisms and oxygen during sewage treatment, leading to a weakened sewage treatment effect. Therefore, a new solution is needed to solve this problem. Utility Model Content
