[0002] A sewage biodegradation pool is a facility for treating sewage. It decomposes organic substances into simpler compounds through biological means, thereby purifying the water quality. Common sewage treatment microorganisms include various bacteria, fungi, and other microorganisms. Through the enzymatic action in the metabolic process, they decompose organic substances into simpler compounds and finally convert them into inorganic substances and new biomass. This process is called biodegradation, which is the core of the sewage biological treatment process. To provide oxygen, an aeration system is usually installed in the bioreactor. It introduces air or oxygen into the bioreactor to maintain the oxygen level required for the growth and metabolism of microorganisms. Existing sewage biodegradation pools mainly install mechanical equipment on the water surface to introduce external environmental gases into the water solution, increasing the oxygen content in the water body. However, the contact effect between oxygen and the water solution is limited, and the dissolution amount is relatively low, resulting in a low degradation efficiency of microorganisms in the sewage. In view of this, research and improvement are carried out on the existing problems, and a sewage biodegradation pool is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.

An aeration stone 330 is fixedly installed inside the drive seat 310, and a plurality of air inlet windows 313 are provided on the surface of the drive seat 310 and are uniformly arranged in a circumferential direction on the outer periphery of the aeration stone 330. A partition board 314 is fixedly installed inside the drive seat 310. The scroll compressor 320 includes a moving slide plate 321, a first spiral strip 322, and a second spiral strip 323 fixedly installed on the bottom surface of the top cover 311. The first spiral strip 322 is fixedly installed on the surface of the moving slide plate 321. The output end of the drive seat 310 passes through the aeration stone 330 and the partition board 314 and is fixedly connected to the bottom surface of the moving slide plate 321.

[0024] In this embodiment, a microbial culture bed is provided on the surface of the microbial colonization 200 and a microbial flora for sewage degradation treatment is attached.

[0025] In this embodiment, the top horizontal height of the liquid surface floating pipe 312 is higher than the liquid surface height of the top surface of the degradation tank 100, and a rain cap is fixedly installed at the top end of the liquid surface floating pipe 312.

[0026] Specifically, external air flow is introduced through the top end of the liquid surface floating pipe 312, and the air flow is transported to the bottom end of the degradation tank 100.

[0027] In this embodiment, the center of the moving slide plate 321 deviates from the axis of the driving seat 310, and the motor and the motor shaft inside the driving seat 310 are coaxial with the driving seat 310.

[0028] Furthermore, balls that slide relative to the top surface of the partition plate 314 are provided on the bottom surface of the moving slide plate 321, and the moving slide plate 321 is slidably installed inside the partition plate 314.

[0029] Specifically, the motor inside the driving seat 310 drives the moving slide plate 321 and the first spiral bar 322 on the surface of the partition plate 314 to swing eccentrically, and the second spiral bar 323 remains relatively stationary.

[0030] In this embodiment, both the first spiral bar 322 and the second spiral bar 323 are planar spiral bar structures, and the first spiral bar 322 and the second spiral bar 323 are located on the same horizontal plane.

[0031] Specifically, the air flow is transported and compressed between the first spiral bar 322 and the second spiral bar 323, and moves through the air pump on the bottom surface of the partition plate 314 and is diffused through the aeration stone 330.

[0032] In this embodiment, the aeration stone 330 is porous and loose, including a large number of micropores and air holes. The micropores and air holes are evenly distributed, forming a dense pore network.

[0034] The working principle and usage process of the present utility model:

[0035] In sewage treatment, microorganisms attach to the surface of the microorganism implantation 200 and grow. The internal water flow in the degradation tank 100 fully contacts the surface of the microorganism implantation 200 through the flow channels formed by the interlacing of several degradation tanks 100. Inside the drive seat 310, the motor drives the movable slide plate 321 and the first spiral bar 322 on the surface of the partition plate 314 to swing eccentrically, while the second spiral bar 323 remains relatively stationary. The airflow inside the liquid surface floating pipe 312 is introduced and transported between the first spiral bar 322 and the second spiral bar 323. Through the air pump movement at the bottom surface of the partition plate 314, it passes through the aeration stone 330. The function of the head of the aeration stone 330 is to release compressed air or oxygen into the water through micropores. By using the motor inside the drive seat 310 to drive the movable slide plate 321 and the first spiral bar 322 to swing eccentrically, gas pumping and compression are carried out to increase the air pressure, and in cooperation with the aeration stone 330, the compressed air is released into the water through micropores, reducing the bubble diameter, thereby increasing the oxygen content in the water and promoting the respiration and growth of organisms in the water.
