Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a high-efficiency wastewater aeration tank. Background Art

[0002] Aeration tanks are biochemical reactors designed according to the characteristics of microorganisms. Aeration is a means of making air and water come into strong contact, with the purpose of dissolving oxygen in the air into water, or expelling unnecessary gases and volatile substances in water into the air. It is a means of promoting the exchange of substances between gas and liquid, and strengthening the contact between organic matter and microorganisms and dissolved oxygen in the tank, thereby ensuring that the microorganisms in the tank can oxidize and decompose organic matter in sewage under the condition of sufficient dissolved oxygen.

[0003] After searching, the utility model patent with announcement number CN209957498U discloses a high-efficiency aeration tank for sewage treatment, including an aeration tank, an air pipe is arranged at the bottom of the inner cavity of the aeration tank, one end of the air pipe is closed, and the other end extends to the outside of the aeration tank and is connected with a high-pressure gas source, a plurality of aeration heads are evenly installed on the outer wall of the air pipe, the aeration tank is U-shaped, and a rotating shaft is rotatably arranged between the inner walls of the U-shaped aeration tank, a rotating shaft seat is fixedly installed on the outer wall of one side of the aeration tank, and a motor is fixedly installed on the outer wall of the other side of the aeration tank, the motor is connected to an external power supply through a wire, one end of the rotating shaft is inserted into the rotating shaft seat and rotatably connected, and the other end of the rotating shaft is connected to the power shaft of the motor through a coupling, and a plurality of stirring blades are radially arranged on the outer wall of the rotating shaft. The high-efficiency aeration tank for sewage treatment greatly increases the contact area between gas and sewage, and effectively improves the aeration efficiency.

[0004] However, the above patents still have the following shortcomings: the aeration head is only convenient for aeration from the bottom of the aeration tank to the top, and the aeration direction is relatively fixed, which affects the efficiency of aeration; in addition, the wastewater at both ends of the aeration tank is not convenient for contact with the aeration gas, which also affects the quality of aeration. For this reason, we propose a high-efficiency aeration tank for sewage treatment. Utility Model Content
