Common sewage treatment methods include sedimentation, filtration, air flotation, activated sludge process, etc. Air floatation separation device is an important physical separation equipment in sewage treatment, which introduces gas into wastewater to make suspended solids, oil and solid impurities float to the water surface, thereby realizing separation. Its principle is that the pollutants in wastewater are combined with gas bubbles, which are floated and removed under the action of gas bubbles. The connection between air floatation separation device and other sewage treatment technologies is that it can be used as a primary or auxiliary means to optimize the subsequent treatment process, such as sedimentation tank or filtration equipment, to improve the overall sewage treatment efficiency. Using air floatation separation device can bring many benefits: first, it can effectively remove suspended solids, oil and other light substances in wastewater, reducing the burden of subsequent treatment process; second, air floatation separation has high separation efficiency, especially suitable for small suspended particles in wastewater that are difficult to settle; finally, air floatation device occupies small area, easy to operate and maintain, and fast processing speed, so in the process of sewage treatment, air floatation separation device can significantly improve the treatment effect and help achieve more efficient water purification.
[0003] The air floatation separation device of sewage treatment plant introduces micro-bubbles into wastewater, which combines with suspended solids, oil and solid particles in wastewater to form bubble-solid complex. These complexes float to the water surface due to buoyancy, thereby realizing separation from water.

Through the combination of gas bubbles and pollutants, high separation efficiency is achieved. Air floatation device can effectively remove light suspended solids in wastewater, especially for small particles that are difficult to settle. Its working principle improves the efficiency of sewage treatment and reduces the burden of subsequent treatment process.

[0026] The cleaning mechanism includes two drive assemblies fixedly connected to the inside of the shell 1 on both sides, and the drive ends of the two drive assemblies are fixedly connected with transmission shafts 18. The drive assemblies are responsible for providing power, which is transmitted to the cleaning mechanism through the transmission shafts 18. The two drive assemblies are fixedly connected to the two sides of the shell 1 and can operate synchronously to clean the device. The transmission shaft 18 is rotatably connected with a transmission mechanism inside, and the transmission mechanism is rotatably connected with a transmission gear 21 outside.

A through hole is provided between the partition and the bottom of the shell 1. The partition separates the oxygen injection mechanism and the drug delivery mechanism.
[0030] The stirring mechanism includes two stirring motors 6 which are responsible for driving the stirring shaft 7 to rotate, thereby driving a plurality of stirring blades 8 to rotate at high speed. The function of the stirring mechanism is to keep the drugs and water fully mixed, ensuring that the drugs are evenly distributed in the sewage to achieve good treatment effect. The two stirring motors 6 are fixedly connected to the proximal side of the two stirring motors 6. The bottom of the stirring motor 6 is fixedly connected to the stirring shaft 7. The outside of the stirring shaft 7 is fixedly connected to a plurality of stirring blades 8.
[0031] The oxygenator mechanism includes a top plate 11 located at the inner top of the shell 1, which is fixedly connected to support the oxygenation pipe 9.

The bottom of the oxygenation pipe 9 is fixedly connected to the oxygenation shaft 10, which is connected to the oxygenation pipe 9 of the top plate 11. The oxygenation shaft 10 is responsible for generating air bubbles in the water by rotating, enhancing the contact area between oxygen and sewage, and improving the oxygenation effect. The inner part of the shell 1 is fixedly connected to the partition plate 29, which has an L-shaped structure design. The partition plate 29 can effectively separate different working areas and prevent water flow or airflow interference, improving the oxygenation effect. The design of the partition plate 29 takes into account the distribution of air bubbles and the uniformity of sewage flow. The partition plate 29 is an L-shaped block, and it is fixedly connected to the rear side of the oxygenation shaft 10.
[0032] Working principle: The sewage flows into the inside of the shell 1 through the water inlet 28, and then the medicine in the medicine storage box 2 flows into the inside of the shell 1 through the medicine pipe fixed frame 4 fixed to the medicine pipe 3 inside the shell 1. Then the stirring motor 6 fixed to the top of the shell 1 is started by the motor mounting frame 5, which drives the stirring shaft 7 to rotate, and then drives the multiple stirring blades 8 outside the stirring shaft 7 to rotate, so that the dirt and medicine are fully mixed to accelerate the drug water effect rate. The sewage and medicine mixture flows into the rear side of the shell 1 through the through hole at the bottom of the partition plate inside the shell 1. In this process, the sewage backflow pipe 13 guides the treated sewage, which then enters the inside of the oxygenator 12 with the help of the water pump 14. The treated sewage is pressurized by the oxygenator 12, causing air and sewage to mix. Then the treated sewage returns to the inside of the shell 1 through the oxygenation pipe 9, and is released by the oxygenation shaft 10. The air forms small bubbles to separate the sewage and the sewage produced by the reaction of the dirt and the medicine, thereby achieving the function of sewage treatment.
[0033] Then the driving motor 17 fixed in the shell 1 by the motor support plate 16 is started, the driving motor 17 drives the transmission shaft 18 to rotate, then the transmission shaft 18 drives the work shaft 20 to rotate through the belt 19, and then the work shaft 20 drives the transmission gear 21 to rotate, then the transmission gear 21 and the chain 22 are coupled and connected with each other, so as to drive the chain 22 to move, and in the process, the auxiliary gear 24 is driven to rotate, finally the dirt is scraped by the scraper 23 fixedly connected with the chain 22, so that the sewage flows into the inside of the guide block 27, is gathered by the flow gathering block 26 and flows out of the inside of the shell 1, and the treated sewage flows out of the inside of the shell 1 through the water outlet pipe 15, in the above process, the waterproof plate 25 and the bottom of the shell 1 form a cavity, which provides a position for installation of the driving motor 17 and the motor support plate 16.
