Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sewage treatment, especially to a sewage treatment aeration device for environmental engineering. BACKGROUND

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. During the treatment process, it is necessary to prevent the sinking of suspended solids in the tank, strengthen the contact of organic matter with microorganisms and dissolved oxygen in the tank, and ensure that the microorganisms in the tank have sufficient dissolved oxygen to oxidize and decompose organic matter in the sewage. Therefore, an aeration device is needed.

[0003] The Chinese patent with publication number CN221319641U provides a sewage treatment aeration device for environmental engineering, particularly in the technical field of aeration devices. It includes a fixed frame, two groups of which are fixedly installed on the inner wall of the sewage tank. Inside the fixed frame, there are left and right symmetrical vertical rods. A sliding sleeve is slidably installed on the vertical rod. Two groups of sliding sleeves are symmetrically installed on the left and right sides. A linkage plate is fixedly installed between the two groups of sliding sleeves. A rectangular opening is formed through the linkage plate. Multiple groups of aeration pipes are arranged between the two groups of linkage plates. The aeration pipes are equipped with multiple groups of aeration heads. During transmission, the transmission chain drives the transmission column to move in a rectangular path. The transmission column drives the corresponding linkage plate to rise and fall. When the two groups of linkage plates rise and fall synchronously, they drive the multiple groups of aeration pipes to rise and fall in the sewage tank. This facilitates the discharge of oxygen at different depths in the sewage tank by the multiple groups of aeration pipes, achieving the effect of comprehensive aeration of the sewage in the sewage tank.

[0004] However, the existing aeration device needs to be fixedly installed at the bottom of the tank during installation and use. Although this can achieve the purpose of aeration, the impurities in the water can easily block the nozzle of the gas disc when the gas disc is used upward. Moreover, since it is fixed at the bottom of the tank, it cannot achieve aeration of the entire tank. Long-term use not only damages the equipment but also affects the subsequent work of sewage treatment, which is poor in practicality.

[0005] Therefore, the present case proposes a sewage treatment aeration device for environmental engineering to solve the above technical problems. UTILITY MODEL CONTENTS
