Description

Technical Field

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

[0002] The aeration mechanism in sewage treatment is a device used to provide oxygen to the microorganisms in the sewage. In the biological treatment stage, especially in the activated sludge process, aeration is a core step;

[0003] After searching, a Chinese patent discloses a sewage treatment aeration mechanism (authorization announcement number CN219670284U). Although the above patent technology can drive the disc, air outlet pipe, stirring pipe, etc. to rise and fall through the electric cylinder, it is convenient to adjust according to the height of the sewage in the treatment tank, which is convenient for people to use. The cooperation of the motor 2, the transmission toothed belt, the transmission gear 1, the fixed shaft, etc. is convenient to drive the round pipe to rotate, and the round pipe drives the square pipe, the air outlet pipe and the stirring pipe to rotate, stir the sewage, and accelerate the aeration of the sewage, so as to facilitate the air supply of the air supply pipe. Through the cooperation of the round pipe, the air delivery pipe, the square pipe, etc., the gas is transported to the air outlet pipe and the stirring pipe, so that the aeration hole can spray the gas to achieve the aeration of the sewage, and the aeration effect is good;

[0004] However, in the actual application of this patented technology, the above-mentioned sewage treatment aeration mechanism cannot simultaneously link the flow of sewage and air intake when in use. On the one hand, the oxygen supply cannot be adjusted according to the actual demand in the sewage, which may lead to excess or insufficient oxygen supply. When the oxygen supply is excessive, most of the oxygen is not used by microorganisms and escapes from the water surface, causing energy waste. When the oxygen supply is insufficient, the activity of microorganisms is reduced, affecting the sewage treatment effect. On the other hand, if the air intake cannot be adjusted synchronously with the sewage flow, the aeration system may operate in a non-optimal state for a long time, resulting in unnecessary increase in energy consumption and increase in the operating cost of the entire sewage treatment system.

[0015] Through the above technical solution, the water inlet pipe on the top of the upper cover and the drain switch on one side of the sewage tank facilitate the inlet and outlet of sewage, simplify the inlet and outlet operation of sewage, and facilitate the implementation of periodic sewage treatment.

[0016] As a preferred implementation, four supporting legs are fixedly connected to the bottom of the sewage tank.
