[0002] With the increasing awareness of environmental protection and the increasingly prominent problem of water shortage, sewage treatment technology has received widespread attention and application.

[0003] In the process of sewage treatment, by adding coagulants and flocculants to the sewage, the suspended matter, colloidal substances, etc. in the sewage can be formed into larger particles or floccules, which are convenient for subsequent separation and treatment. The flotation technology is to inject air into the sewage to form tiny bubbles, so that these particles or floccules are attached to the bubbles, and then float to the water surface for separation. Traditional sewage treatment equipment is often not sufficient and fast in mixing and reaction. Due to the single stirring method or insufficient stirring intensity, the coagulant and flocculant in the sewage cannot be fully mixed and reacted with the sewage, resulting in low treatment efficiency. Therefore, a sewage treatment flocculation flotation equipment is proposed to solve the above-mentioned problems. Utility Model Content

The two small motors are respectively fixedly connected to both sides of the sliding block 4 near the end, and the output ends thereof pass through the side of the sliding block 4 and are respectively fixedly connected to the two stirring rods 8.

[0029] It should be noted that the accelerated reaction component is the core part of sewage treatment.

This movement method makes the stirring process more comprehensive and helps to improve the mixing and reaction effect of sewage. At the same time, the two small motors 7 drive the stirring rod 8 to rotate and stir respectively, further enhancing the mixing and reaction effect of sewage.

[0030] In this embodiment, sealing rings are arranged outside the rotating rod 3 and at the top and bottom surfaces of the top plate of the reaction box 1 , and a supporting block 13 is rotatably connected to the bottom of the rotating rod 3 .

Two small motors 7 drive two stirring rods 8 to rotate and stir respectively, further enhancing the mixing and reaction effect of the sewage. The design of the feeding trough 10 makes the dosing process more uniform and convenient. The feeding trough 10 is fixed on the sliding block 4 through the fixing frame 9. As the sliding block 4 moves, the feeding trough 10 can add coagulants and flocculants to the sewage at different depths. This design not only improves the mixing and reaction speed, but also enables the coagulants and flocculants to contact and react more fully with the impurities in the sewage, thereby improving the treatment effect. At the same time, the coordinated use of the card plate 11 and the cover plate 12 makes the opening and closing of the feeding trough 10 simple and convenient, while ensuring the safety during the dosing process.
