Hospital wastewater contains large amounts of pathogenic bacteria, viruses, and chemical agents, exhibiting characteristics of spatial pollution, acute infectiousness, and latent infectiousness. Treating hospital wastewater requires the addition of chlorine for disinfection.

[0003] Currently, methods for controlling total residual chlorine within certain limits all employ manual, timed measurement. This involves manually measuring the total residual chlorine in wastewater and then manually controlling the dosage of chlorine-containing disinfectant based on the concentration. However, this method has significant drawbacks: manual measurement is time-consuming, labor-intensive, and costly; it also has a large margin of error, making it impossible to control the dosage in real-time based on wastewater volume; furthermore, the chlorine disinfectant cannot immediately and fully contact the wastewater after being added, resulting in reduced disinfection effectiveness. Therefore, this invention provides a total residual chlorine control system for medical wastewater to address these issues. Summary of the Invention

The system includes a disinfection tank 1, a monitoring cabinet 2, a chlorine storage tank 3, a residual chlorine monitoring sensor 4, a stirring and cleaning structure 5, a detection tube 6, a return pipe 7, and a dosing pipe 8. The monitoring cabinet 2 is equipped with a controller, which can be a PLC controller. The controller stores a target residual chlorine value, a dosing increase value, and a dosing decrease value. One side of the monitoring cabinet 2 has a U-shaped opening 9, and one side of the U-shaped opening 9 has a monitoring tank 10. The residual chlorine monitoring sensor 4 is installed on one side of the monitoring tank 10, with its monitoring probe extending into the monitoring tank 10. One end of the monitoring tank 10 is connected to the disinfection pool 1 via a detection pipe 6, and the other end of the monitoring tank 10 is connected to the disinfection pool 1 via a return pipe 7. The chlorine storage tank 3 is connected to the disinfection pool 1 via a dosing pipe 8. The chlorine storage tank 3 stores sodium hypochlorite (NaClO) reagent. The dosing pipe 8 is equipped with a dosing control valve 11 and a dosing pump 12. The agitation cleaning structure 5 is installed inside the disinfection pool 1. The detection pipe 6 is equipped with a detection pump 23, and the return pipe 7 is equipped with a return pump 24. The controller in the monitoring cabinet 2 is connected to the residual chlorine monitoring sensor 4, the dosing control valve 11, the dosing pump 12, the detection pump 23, and the return pump 24 to realize signal transmission, monitoring, and control. In the treatment of medical wastewater, wastewater is pumped into a monitoring tank via a detection pipe and pump. A residual chlorine sensor in the monitoring tank monitors the chlorine concentration of the wastewater in real time. The detection pipe is installed inside the disinfection tank, and the detection pump is mounted on the side wall of the disinfection tank. The monitored wastewater is pumped back into the disinfection tank via a return pipe and pump. The return pipe is located above the disinfection tank, and the return pump is mounted on a crossbar for easy real-time chlorine concentration monitoring. This eliminates the need to install the residual chlorine sensor inside the disinfection tank. The sensor can monitor the chlorine concentration in the medical wastewater in real time, and the controller... It stores the residual chlorine target value, the dosage increase value, and the dosage decrease value. When the real-time chlorine concentration is less than the dosage increase value, the dosage is increased through the dosage control valve. When the real-time chlorine concentration is greater than the dosage decrease value, the dosage is reduced. When the chlorine concentration reaches the residual chlorine target value, the dosing is stopped. This facilitates control of the dosage and improves the treatment effect. At the same time, the stirring and cleaning structure can stir the wastewater and the agent during the treatment process, so that the two are fully mixed and in contact, improving the treatment effect. During the stirring process, the brush can remove the sediment on the inner wall of the disinfection tank and clean the inner wall of the disinfection tank.

[0019] The agitation cleaning structure 5 includes a motor 13, a stirring shaft 14, a stirring rod 15, and a brush plate 16. Support columns 17 are installed around the top of the disinfection tank 1, and a cross 18 is installed on the top of each support column 17. The motor 13 is mounted on the cross 18, and the stirring shaft 14 is also mounted on the cross 18. One end of the stirring shaft 14 extends into the disinfection tank 1, and the other end is connected to the output shaft of the motor 13. Multiple stirring rods 14 are evenly installed on both sides of the stirring shaft 14. A brush plate 16 is vertically mounted on one end of each stirring rod 14, and a brush is provided on the side of the brush plate 16 near the inner wall of the disinfection tank 1. The motor is connected to a controller. During agitation, the motor is started, causing the stirring shaft to rotate, which in turn rotates the stirring rod and the brush plate, ensuring thorough mixing and contact between the medical wastewater and the reagent. Simultaneously, the brush on one side of the brush plate can scrub the inner wall of the disinfection tank.

[0020] The monitoring cabinet 2 is equipped with a control panel 19 on the front side. The control panel 19 is equipped with a display screen 20 and function buttons 21.

[0022] Work process:

[0023] The working principle of this utility model is as follows: During the treatment of medical wastewater, wastewater is pumped into the monitoring tank 10 through the detection pipe 6 and the detection pump 23. The residual chlorine monitoring sensor 4 in the monitoring tank 10 can monitor the chlorine concentration of the wastewater in real time. The detection pipe 6 is installed in the disinfection tank 1, and the detection pump 23 is installed on the side wall of the disinfection tank 1. The monitored wastewater is pumped back into the disinfection tank 1 through the return pipe 7 and the return pump 24. The return pipe 7 is located above the disinfection tank 1, and the return pump 24 is installed on the cross 18, which facilitates real-time monitoring of chlorine concentration. It is not necessary to install the residual chlorine monitoring sensor 4 in the disinfection tank, which facilitates monitoring. The monitoring sensor can monitor the chlorine concentration in the medical wastewater in real time. The system stores a residual chlorine target value, a dosage increase value, and a dosage decrease value. When the real-time chlorine concentration is less than the dosage increase value, the dosage is increased through the dosage control valve 11. When the real-time chlorine concentration is greater than the dosage decrease value, the dosage is decreased through the dosage control valve 11. When the chlorine concentration reaches the residual chlorine target value, the dosing is stopped, which facilitates control of the dosage and improves the treatment effect. At the same time, the stirring cleaning structure 5 can stir the wastewater and the agent during the treatment process. When stirring, the motor 13 is started, which makes the stirring shaft 14 rotate, driving the stirring rod 15 and the brush plate 16 to rotate, so that the medical wastewater and the agent are fully mixed and contacted. At the same time, the brush on one side of the brush plate 16 can scrub the inner wall of the disinfection tank.
