Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment technical field, concretely relates to a kind of aeration precipitation integrated sewage treatment device. BACKGROUND

[0002] In the sewage treatment process, aeration and sedimentation are usually sequential steps, which are crucial for improving the efficiency of sewage treatment and improving water quality. Specifically, sewage is first treated by aeration, and the oxygen in the air is dissolved in the sewage, or the useless volatile substances in the sewage are expelled into the air. Subsequently, the sewage enters the sedimentation tank, and the density difference between the suspended particles in the water and the sewage is utilized to realize solid-liquid separation under the action of gravity, further purifying the water quality.

[0003] Due to the need for sufficient agitation and oxygen supply during aeration, this usually involves high flow rates and turbulence levels to ensure uniform distribution of oxygen. On the other hand, sedimentation requires lower speeds and turbulence to allow suspended particles in the sewage to settle under the action of gravity. Since aeration and sedimentation require different operating conditions and equipment to achieve their respective goals, they are usually designed separately. However, separate design means an increase in the total floor area of the entire sewage treatment equipment, resulting in increased construction and operating costs, and also increasing the risk of pipeline failure. Therefore, an aeration and sedimentation integrated sewage treatment device is needed to solve the above problems. SUMMARY
