Description

Technical Field

[0001] The present invention specifically relates to the technical field of sewage treatment, and in particular to an aeration and sedimentation integrated sewage treatment device. Background Art

[0002] Sewage treatment (wastewater treatment) is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] Aeration tanks are biochemical reactors designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by people. Aeration tanks use the activated sludge method to treat sewage. A certain sewage retention time is provided in the tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. However, the aeration pipes in existing aeration tanks are laid at the bottom of the pool, so that aerobic microorganisms in the upper sewage in the aeration tank cannot obtain enough dissolved oxygen, which leads to a decrease in the efficiency of aerobic microorganisms in sewage treatment. The overall aeration degree of sewage is uneven, and due to aeration, a large number of bubbles will float on the surface of the pool water, affecting the water quality. Summary of the invention
