Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 3 , a sewage treatment sterilization and disinfection device, including a bottom plate 1, a disinfection chamber 2 fixedly connected to the upper surface of the bottom plate 1, a water inlet pipe 3 and a servo motor 4 fixedly connected to the upper surface of the disinfection chamber 2, a stirring rod 5 fixedly connected to the output shaft of the servo motor 4, and stirring blades 6 fixedly connected to the outside of the stirring rod 5. A chemical agent feeding structure is provided on the upper surface of the bottom plate 1.

[0025] As Figure 1 shown, the chemical agent feeding structure includes a chemical agent tank 7 fixedly connected to the upper surface of the bottom plate 1, an infusion pump 8 fixedly connected to the upper surface of the chemical agent tank 7, a liquid extraction pipe 9 fixedly connected to the extraction end of the infusion pump 8, a first solenoid valve 10 fixedly connected to the other end of the liquid extraction pipe 9, a liquid outlet pipe 11 fixedly connected to the output end of the infusion pump 8, and a pH sensor 12 and a turbidity sensor 13 fixedly connected to the inside of the disinfection chamber 2;

[0026] A secondary treatment assembly for improving the sterilization and disinfection effect is provided at the bottom of the disinfection chamber 2.

[0027] It should be noted that support feet 201 are respectively fixedly connected to the four corners of the bottom of the disinfection chamber 2, and the bottom ends of the support feet 201 are fixedly connected to the upper surface of the bottom plate 1.

[0028] The bottom end of the stirring rod 5 movably penetrates the upper surface of the disinfection chamber 2 and extends to the inside of the disinfection chamber 2 and is fixedly connected to the stirring blades 6.

[0029] The first solenoid valve 10 is fixedly connected to the left side wall of the chemical agent tank 7 and is communicated with the liquid outlet of the chemical agent tank 7. The end of the liquid outlet pipe 11 away from the infusion pump 8 is fixedly connected to the upper surface of the disinfection chamber 2 and is communicated with the liquid inlet of the disinfection chamber 2.

[0030] The pH sensor 12 and the turbidity sensor 13 are both fixedly connected to the inner rear side wall of the disinfection chamber 2, and a foreign object interception net 14 is laid on the inner bottom wall of the disinfection chamber 2.

[0031] The secondary treatment assembly includes a second electromagnetic valve 15 fixedly connected to the bottom of the disinfection chamber 2, a secondary treatment tank 16 fixedly connected to the liquid outlet end of the second electromagnetic valve 15, ultraviolet lamps 17 respectively fixedly connected to the inner front side wall and the inner rear side wall of the secondary treatment tank 16, activated carbon plates 18 respectively fixedly connected to the inner front side wall and the inner rear side wall of the secondary treatment tank 16, and a third electromagnetic valve 19 fixedly connected to the front of the secondary treatment tank 16.

[0032] The secondary treatment tank 16 is fixedly connected to the upper surface of the bottom plate 1, and the activated carbon plate 18 is located between two adjacent ultraviolet lamps 17 on the same side.

[0033] In addition, a chemical agent replenishment port is provided on the front of the chemical agent tank 7, and the chemical agent replenishment port is provided with a matching cover. Through the filtering action of the foreign object interception net 14, the content of solid impurities in the sewage entering the secondary treatment tank 16 can be reduced, and the suspension or impurities in the sewage can be prevented from blocking the irradiation path of the ultraviolet rays, thereby ensuring the use effect of the ultraviolet lamp 17.

[0034] The working principle of the above embodiment is as follows:

[0035] When the sewage treatment process starts, according to the preset pH value and turbidity value, the control system activates the infusion pump 8, accurately extracts the required amount of chemical agent through the liquid extraction pipe 9 and the first electromagnetic valve 10, and injects it into the disinfection chamber 2 through the liquid outlet pipe 11. The pH sensor 12 and the turbidity sensor 13 continuously monitor the changes in the pH value and turbidity of the sewage, and feed the data back to the control system, so as to adjust the dosage of the chemical agent and avoid waste caused by excessive use of the chemical agent;

[0036] After the chemical agent enters the disinfection chamber 2 and is mixed with the sewage, the servo motor 4 is started at this time. The servo motor 4 drives the stirring rod 5 and the stirring blade 6 to rotate in the disinfection chamber 2, forming a strong water flow disturbance, promoting the full mixing of the chemical agent and the sewage, ensuring that the chemical agent can be evenly distributed in the sewage, and improving the efficiency and uniformity of disinfection and sterilization;

[0037] After the preliminary treatment is completed, the preliminarily treated sewage enters the secondary treatment tank 16 through the second electromagnetic valve 15. And in this process, the foreign object interception net 14 intercepts the solid impurities in the sewage to prevent the solid impurities from blocking the second electromagnetic valve 15. When the sewage enters the inside of the secondary treatment tank 16, the ultraviolet rays emitted by the ultraviolet lamp 17 act on the microorganisms in the sewage, destroying their DNA structure to achieve the purpose of highly efficient sterilization. At the same time, the activated carbon plate 18 uses its strong adsorption ability to further remove harmful substances such as organic pollutants and residual chlorine in the sewage and improve the water quality.

[0038] All electrical components appearing in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology will not be elaborated in the text.
