[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] like Figure 1-4As shown, this utility model provides a high-efficiency wastewater disinfection treatment reactor, including a tank body 1, a partition 2, a chemical inlet pipe 3, a chemical mixing box 4, and chemical dispensing pipes 5. The partition 2 is disposed in the tank body 1, dividing the tank body 1 into multiple wastewater tanks 101 in parallel. The chemical mixing box 4 is installed on the tank body 1, and the top is connected to the chemical inlet pipe 3 for inputting disinfectant into the chemical mixing box 4. Multiple chemical dispensing pipes 5 are evenly connected to both sides of the chemical mixing box 4. The outlet ends of the chemical dispensing pipes 5 are respectively located in multiple wastewater tanks 101, so that the disinfectant can be added to multiple positions in the disinfection tank at the same time. The partition 2 is divided into a high plate 201 and a low plate 202, which are staggered. The upper end of the high plate 201 is higher than the upper end of the low plate 202, and the lower end of the high plate 201 is separated from the bottom of the tank body 1 by a certain distance. A connecting port 203 is provided to connect two connected sewage tanks 101. The lower end of the lower plate 202 is closed and connected to the bottom of the pool body 1, and the upper end is lower than the height of the high plate 201, so that the sewage flows vertically and directionally between multiple sewage tanks 101. The sewage flows from the connecting port 203 at the lower end of the high plate 201 to the next sewage tank 101 and flows upward, and from the upper end of the lower plate 202 to the next sewage tank 101. The upper end of the right side wall of the pool body 1 is provided with an outlet 102 for the sewage to overflow after disinfection. The left end of the pool body 1 is connected to an inlet pipe 103 for sewage to enter the pool body 1. The top of the pool body 1 is provided with a fixing plate 104, and multiple stirring devices 6 are installed on the fixing plate 104 to stir the sewage in each sewage tank 101 evenly. When the reaction tank is in operation, the wastewater to be disinfected flows into the leftmost wastewater tank 101 through the inlet pipe 103. The disinfectant flows into the dosing box 4 through the dosing pipe 3, and then flows into each wastewater tank 101 through the distribution pipe 5. The disinfectant flowing into the leftmost wastewater tank 101 disinfects the wastewater. The stirring device 6 stirs the wastewater. Combined with the disinfection effect of the disinfectant, the wastewater then flows from the connecting port 203 at the bottom of the high plate 201 into the next wastewater tank 101. The disinfectant flowing into the second wastewater tank 101 disinfects the wastewater again. Then, the wastewater flows from the top of the low plate 202 into the next wastewater tank 101, where the disinfectant disinfects the wastewater again. This process is repeated, with the wastewater flowing from left to right through multiple wastewater tanks 101. The wastewater is disinfected multiple times, and finally flows out from the rightmost outlet 102 into the clear water tank. The disinfection treatment reaction tank of this utility model is divided into multiple wastewater tanks 101 by a partition 2 consisting of a high plate 201 and a low plate 202. This allows the wastewater to flow vertically and directionally between the multiple wastewater tanks 101. Each wastewater tank 101 is evenly equipped with a dispensing pipe 5 for adding disinfectant, so that the wastewater can be disinfected in each wastewater tank 101. This repeated disinfection of the wastewater improves the disinfection effect. Furthermore, the dispensing box 4 connects to multiple dispensing pipes 5 at the same time, allowing the disinfectant to reach multiple locations for disinfection simultaneously, improving the efficiency of disinfectant addition and thus improving the efficiency of wastewater disinfection.

[0018] The partition 2 closest to the outlet 102 is a high plate 201, which allows the water in the last sewage tank 101 to flow from bottom to top, so that the sewage can be fully disinfected and flow out from the outlet 102 into the clear water tank.

[0019] The dispensing end of the dispensing pipe 5 in the sewage tank 101 where water flows downward is located at the upper part of the sewage tank 101, which can fully disinfect the sewage and prevent the disinfectant from flowing too quickly from the lower connecting port 203 into the next sewage tank 101, thereby reducing the disinfection effect. The dispensing end of the dispensing pipe 5 in the sewage tank 101 where water flows upward is located at the lower part of the sewage tank 101, which allows the disinfectant to flow upward with the sewage and disinfect the sewage, preventing the disinfectant from flowing too quickly from the upper end into the next sewage tank 101.

[0020] The stirring device 6 includes a stirring shaft 601 and stirring rods 602. The stirring shaft 601 is rotatably mounted on a fixed plate 104 via bearings, with its lower end submerged in the sewage in the tank 1. The stirring rods 602 are evenly connected to the side walls of the stirring shaft 601. A motor 603 is mounted on the fixed plate 104, and the motor 603 is connected to the upper end of the stirring shaft 601 via belt drive. Multiple stirring shafts 601 are interconnected via belt drives. The motor 603 drives the stirring shaft 601 and stirring rods 602 to rotate, stirring the sewage, accelerating the mixing of disinfectant and sewage, and improving the disinfection efficiency of the disinfectant on the sewage.

[0021] The stirring shaft 601 is a hollow rod structure with an open top. A second fixing plate 105 is connected to the first fixing plate 104 via support plates at both ends. An air-blowing device 7 is installed on the second fixing plate 105. The air outlet of the air-blowing device 7 is connected to the upper opening of the stirring shaft 601 via multiple air-blowing pipes 701. The air-blowing pipes 701 and the upper opening of the stirring shaft 601 are rotatably connected via bearings, ensuring that air is blown into the stirring shaft 601 without affecting its rotation. Multiple air outlets 6011 are evenly distributed on the side wall of the stirring shaft 601. The air-blowing device 7 blows air into the stirring shaft 601 through the air-blowing pipes 701. The air is evenly discharged into the wastewater from the air outlets 6011 on the side wall of the stirring shaft 601. Under the coordinated stirring of the stirring rod 602, the mixing of air and wastewater promotes uniform mixing of the disinfectant and wastewater, improving the disinfection efficiency of the disinfectant.

[0022] The air blowing device 7 includes an air distribution box 702, a fixed cylinder 703, a fan blade 704, and a second motor 705. The air distribution box 702 is a hollow structure and is fixedly installed on a second fixed plate 105. Multiple air blowing pipes 701 are respectively connected to the side wall of the air distribution box 702. The lower end of the fixed cylinder 703 is a funnel structure and is fixedly connected to the top of the air distribution box 702. A connecting plate 706 is provided on the top of the fixed cylinder 703. The fan blade 704 is rotatably installed on the bottom of the connecting plate 706. The fan blade 704 is located in the fixed cylinder 703 and is connected to the second motor 705 installed on the connecting plate 706. Motor 705 drives fan blade 704 to rotate, generating airflow that blows air along fixed cylinder 703 into air distribution box 702, thereby simultaneously blowing air into multiple air blowing pipes 701 and multiple stirring shafts 601, so that air is simultaneously blown into multiple sewage tanks 101, promoting the mixing of disinfectant and sewage and improving the disinfection efficiency of disinfectant on sewage.

[0023] Working process: When the reaction tank is in operation, the wastewater to be disinfected flows into the leftmost wastewater tank 101 through the inlet pipe 103. The disinfectant flows into the dosing box 4 through the dosing pipe 3, and then flows into each wastewater tank 101 through the distribution pipe 5. The disinfectant flowing into the leftmost wastewater tank 101 disinfects the wastewater. The stirring device 6 stirs the wastewater. Combined with the disinfection effect of the disinfectant, the wastewater then flows from the connecting port 203 at the bottom of the high plate 201 into the next wastewater tank 101, where the disinfectant flows into the second wastewater tank 101. The wastewater is disinfected again, and then flows from the top of the lower plate 202 into the next wastewater tank 101. The disinfectant disinfects the wastewater again, and this process is repeated. The wastewater flows through multiple wastewater tanks 101 from left to right, thus disinfecting the wastewater multiple times. Finally, it flows out from the rightmost outlet 102 and is discharged into the clear water tank. At the same time, the stirring rod 602 stirs the wastewater, and the air outlet 6011 on the side wall of the stirring shaft 601 blows air into the wastewater to promote the mixing of the disinfectant and the wastewater and improve the disinfection efficiency of the disinfectant.
