Description

Technical Field

[0001] This utility model relates to an aeration device, specifically a gas-liquid mixing aeration device, belonging to the field of wastewater treatment technology. Background Technology

[0002] Aeration refers to the artificial introduction of air into a biological aeration tank using appropriate equipment to achieve a desired effect. Aeration not only brings oxygen into the tank by contacting the liquid with air, but also accelerates the transfer of oxygen from the air into the liquid due to liquid agitation, thus achieving the goal of oxygenation. In addition, aeration also prevents suspended solids from settling and enhances the contact between organic matter and microorganisms with dissolved oxygen, thereby ensuring that microorganisms in the tank can oxidize and decompose organic matter in wastewater under conditions of sufficient dissolved oxygen.

[0003] A mixing aeration device for industrial wastewater treatment, disclosed in Chinese Patent Application Publication CN217868357U, involves a motor that drives a reciprocating screw to rotate. This rotating screw, through a threaded structure, moves a connected placement plate. The placement plate then slides back and forth outside the screw and guide rod, smoothly driving the blower and aerators above to move back and forth within the sedimentation tank. This effectively aerates the water in the entire sedimentation tank. Rotating blades are installed on the outer walls of several fixed semi-rings. During use, when the first air guide pipe moves along the moving assembly, the blades on the first air guide pipe slide back and forth, contacting the water in the sedimentation tank and rotating. This rotation stirs the water, ensuring more thorough mixing and improving the aeration effect.

[0004] In the above patented solutions, the water source can be smoothly stirred by the rotation of the blades, making the water source in the sedimentation tank more thoroughly mixed. Therefore, it can improve the aeration effect of the water source in the sedimentation tank to a certain extent. However, the rotation of the blades of this device can only be driven by the water source in the sedimentation tank, and the rotation speed is low, which will result in insufficient mixing of the water source in the sedimentation tank and reduce the aeration effect.

[0005] Therefore, a gas-liquid mixing aeration device is proposed here. Utility Model Content
