Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment aeration device. Background Art

[0002] At present, aeration is often used to treat sewage. Air is artificially introduced into the aeration tank to prevent the suspended matter in the tank from sinking and to strengthen the contact between the 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. However, the existing aeration device will cause impurities in the sewage to accumulate at the bottom of the treatment tank and cannot come into contact with the air, resulting in a dead corner for aeration treatment, which makes it difficult to meet the demand for thorough sewage treatment.

The surface of the transverse screw is threadedly connected to the fixing frame, and the surface of the fixing frame is respectively provided with an aeration component and a cleaning component. The transverse screw is driven to rotate by a servo motor so that the fixing frame moves horizontally inside the aeration tank. During the horizontal movement, the air in the external gas tank is transported to the aeration head through the vertical pipe and the horizontal pipe, and then the air floats up to achieve the purpose of aerating the sewage. The roller brush is driven to rotate by the waterproof motor, so that the bottom of the aeration tank can be stirred, the fluidity of the sewage at the bottom of the aeration tank is enhanced, the dead corner of aeration treatment is eliminated, and impurities are prevented from settling at the bottom of the aeration tank, thereby ensuring the effect of sewage treatment.

[0004] However, in the above-mentioned prior art, when air floats up from the bottom of the aeration tank, the volume of the bubbles gradually increases due to the decrease in air pressure, causing the dissolved oxygen content of the sewage in the upper layer to decrease, resulting in poor aeration effect.
