Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically relates to a precise aeration system for a sewage aerobic aeration tank. Background Art

[0002] Aeration refers to the artificial introduction of air into the biochemical aeration tank through appropriate equipment in order to increase the dissolved oxygen in the wastewater. Aeration not only allows the liquid in the tank to come into contact with air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the stirring of the liquid, thereby completing the purpose of oxygenation. In addition, aeration also prevents the suspended matter in the tank from sinking and strengthens the contact between the organic matter and microorganisms in the tank and the dissolved oxygen, thereby ensuring that the microorganisms in the tank can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] In conventional integrated sewage treatment devices, in order to achieve the effect of precise aeration, a Chinese patent (publication number: CN202222783212.4) discloses a precise aeration integrated sewage treatment device, which has a facility in the sedimentation tank to drive the aeration pipe to move in the tank body to achieve the effect of precise aeration. However, when the device is aerating, the flow of gas needs to be controlled by a separate air intake fan, which increases the consumption of electric energy, and the driving structure is arranged at the bottom of the tank body, which may be damaged due to being soaked in sewage for a long time. Therefore, a precise aeration system for a sewage aerobic aeration tank is needed to solve the above problems. Utility Model Content
