[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a wastewater treatment device for pharmaceutical and chemical industries includes a treatment tank 11; an outlet pipe 12 is fixedly connected to the top of the treatment tank 11, an inlet pipe 13 is fixedly connected to the bottom of the treatment tank 11, a central pipe 15 is fixedly connected to the middle of the treatment tank 11, a plurality of partitions 16 are fixedly connected between the central pipe 15 and the inner wall of the treatment tank 11, a plurality of treatment chambers are fixedly connected inside the treatment tank 11 by the partitions 16, and a connecting pipe 17 is fixedly connected to the partitions 16, and two adjacent treatment chambers are connected by a connecting pipe. The bottom of the treatment tank 11 is connected to the air injection assembly of the bottom of the treatment tank 11, and the top of the treatment tank 11 is provided with an exhaust pipe 14. The air injection assembly includes a distribution pipe seat 21, a plurality of air distribution pipes 22 and a plurality of air injection pipes 23. The pipe seat 21 is fixed to the bottom of the treatment tank 11, the plurality of air distribution pipes 22 are fixed to the pipe seat 21, the plurality of air injection pipes 23 are fixed to the air distribution pipes 22, the top end of the air distribution pipe 22 penetrates the bottom wall of the pipe seat 21 and is fixed thereto, and the top end of the air distribution pipe 22 is inserted into the interior of the treatment chamber.

[0024] In use, medical wastewater is injected into the treatment tank 11 through the inlet pipe 13, and then discharged through the outlet pipe 12. The treatment tank 11 is equipped with multiple baffles 16 to divide it into multiple treatment chambers, which are connected by connecting pipes 17. An ozone injection component is installed at the bottom to inject ozone, and then the exhaust pipe 14 discharges the gas. With the above structure, the reaction between ozone and wastewater can be enhanced, and the reaction can be made more complete, thereby improving the wastewater treatment effect. In use, the bottom of the external ozone pipe and the pipe seat 21 are connected, and multiple gas distribution pipes 22 are distributed through the pipe seat 21. Multiple gas injection pipes 23 are fixed to the gas distribution pipes 22, and ozone is injected into individual treatment chambers through the gas injection pipes 23, so as to facilitate the oxidation of organic matter in wastewater by ozone.

[0025] Furthermore, such as Figure 1-5 As shown, the connecting pipe 17 is arranged in an L-shape. A uniform distribution plate 41 is fixedly connected to the bottom of the processing chamber. The bottom end of the connecting pipe 17 passes through the uniform distribution plate 41 and is fixedly connected to it. The uniform distribution plate 41 has multiple through holes 42. A uniform distribution disk 31 is fixedly connected to the top end of the gas injection pipe 23. The gas injection pipe 23 and the uniform distribution disk 31 are connected internally. A gas distribution port 32 is opened at the top of the uniform distribution disk 31. The uniform distribution disk 31 is located below the uniform distribution plate 41.

[0026] In use, the connecting pipe is arranged in an L-shape, and a uniform distribution plate 41 is installed at the bottom of the treatment chamber. The connecting pipe injects sewage into the bottom of the uniform distribution plate 41, and then it flows up from the through hole 42 above the uniform distribution plate 41. Therefore, it can disperse the sewage and facilitate the contact between sewage and ozone for oxidation reaction. The top of the air injection pipe 23 is fixed with a uniform distribution disk 31, and the air injection pipe 23 and the uniform distribution disk 31 are connected. An air distribution port 32 is opened above the uniform distribution disk 31 to disperse the ozone and form multiple small airflows, so as to facilitate the full contact reaction between sewage and ozone.

[0027] Furthermore, such as Figure 1-5 As shown, the central tube 15 is made of transparent glass, and an ultraviolet lamp 5 is fixed to the top of the treatment tank 11. The ultraviolet lamp 5 is inserted into the interior of the central tube 15. A reflector 6 is fixed to the inner wall of the treatment tank 11, and the reflector 6 can reflect light.

[0028] When in use, the ultraviolet lamp 5 is powered on, and it generates ultraviolet light to irradiate the inside of the treatment tank 11. The ultraviolet light catalyzes the decomposition of antibiotics, endocrine disruptors and some organic matter, thereby playing an auxiliary role in the treatment of sewage and improving the treatment effect. The reflector plate 6 is used to reflect ultraviolet light, so as to facilitate the full treatment of ultraviolet light.

[0029] Working principle: During use, medical wastewater is injected into the treatment tank 11 through the inlet pipe 13, and then discharged through the outlet pipe 12. The treatment tank 11 is divided into multiple treatment chambers by multiple baffles 16, which are connected by connecting pipes 17. An ozone injection component is installed at the bottom to inject ozone, and the gas is discharged through the exhaust pipe 14. This structure enhances the reaction between ozone and wastewater, improves the sufficiency of the reaction, and increases the effectiveness of wastewater treatment. During use, the external ozone pipe is connected to the bottom of the pipe seat 21, and multiple gas distribution pipes 22 are distributed through the pipe seat 21. Multiple injection pipes 23 are fixed to the gas distribution pipes 22, injecting ozone into individual treatment chambers through the injection pipes 23. This facilitates the oxidation of organic matter in the wastewater by ozone. During use, the connecting pipes are arranged in an L-shape. A uniform distribution plate 41 is installed at the bottom of the treatment chamber. Wastewater is injected into the bottom of the uniform distribution plate 41 through the connecting pipe and then flows up through the through hole 42 above the uniform distribution plate 41. This disperses the wastewater and facilitates contact between the wastewater and ozone for oxidation. A uniform distribution plate 31 is fixed to the top of the air injection pipe 23, and the air injection pipe 23 and the uniform distribution plate 31 are connected. An air distribution port 32 is opened above the uniform distribution plate 31 to disperse the ozone and form multiple small airflows, so that the wastewater and ozone can fully contact and react. When in use, the ultraviolet lamp 5 is powered on, and it generates ultraviolet rays to irradiate the inside of the treatment tank 11. The generated ultraviolet rays catalyze the decomposition of antibiotics, endocrine disruptors and some organic matter, thereby playing an auxiliary role in the treatment of wastewater and improving the treatment effect. The reflector plate 6 is used to reflect ultraviolet rays and facilitate the full treatment of ultraviolet rays.
