[0021] The opening and closing assembly includes a fixed plate 6, which is horizontally fixed to the bottom end of the side of the treatment tank 1, and a hydraulic cylinder 7 is vertically fixed to the top of the fixed plate 6.

The bottom end of the connecting rod 9 is fixed to the top of the upper cover 10. Specifically, when the hydraulic cylinder 7 is running, the connecting plate 8 can be driven to rise and fall, and the upper cover 10 can be driven to rise and fall through the connecting rod 9, so that the upper cover 10 can be controlled to move down and close with the treatment tank 1, so as to meet the sealing requirements of the internal space of the treatment tank 1 and prevent ozone leakage;

[0022] The stirring assembly includes a servo motor 11, which is vertically fixed at the top center of the upper cover 10. The output shaft of the servo motor 11 vertically passes through the upper cover 10, and a rotating shaft 12 is fixed to the bottom end of the output shaft of the servo motor 11, and a stirring paddle 13 is fixed to the bottom end of the rotating shaft 12. Specifically, when the servo motor 11 is running, the stirring paddle 13 can be driven by the rotating shaft 12 to rotate in the treatment tank 1, so that the sewage and ozone can be stirred and mixed, which is beneficial to the catalytic effect of ozone on the oxidation of sewage;

[0023] The filter assembly includes a filter plate 14, which is in the shape of a disc. The rotating shaft 12 vertically passes through the center of the filter plate 14, and the surface of the rotating shaft 12 is fixedly connected to the center of the filter plate 14. The horizontal plane of the filter plate 14 is located below the horizontal plane of the sewage inlet pipe 2. Specifically, when the sewage is injected into the treatment tank 1, it can be first filtered by the filter plate 14 to effectively filter out impurities in the sewage. When the hydraulic cylinder 7 drives the upper cover 10 to move up and down, the filter plate 14 can be driven to rise and fall synchronously, so that the filter plate 14 can be conveniently moved out of the treatment tank 1. Therefore, while meeting the sealing requirements of the internal space of the treatment tank 1, the device can also conveniently move the filter plate 14 out of the treatment tank 1, so as to facilitate the cleaning of the blocked filter plate 14.

[0024] The ozone adding component includes an annular bracket 15, the outer ring surface of the annular bracket 15 is fixed on the upper side of the inner surface of the treatment tank 1, and the edge of the lower surface of the filter plate 14 fits with the upper surface of the annular bracket 15, so that the sewage can effectively flow through the gap between the filter plate 14 and the annular bracket 15, ensuring the filtering effect of the filter plate 14 on sewage impurities. A plurality of connecting rods 16 are vertically fixed on the lower surface of the annular bracket 15, and an annular exhaust pipe 17 is fixed at the bottom end of the plurality of connecting rods 16. The bottom of the annular exhaust pipe 17 is evenly fixed and connected with a plurality of exhaust ports 18, and the stirring paddle 13 is located on the inner side of the annular exhaust pipe 17. Specifically, the setting of the annular exhaust pipe 17 and the annular bracket 15 does not affect the lifting and lowering of the stirring paddle 13 and the filter plate 14;

[0025] The ozone adding component also includes an ozone generator 19 and an air pump 20, which are disclosed to those skilled in the art and will not be described in detail. The ozone generator 19 is arranged on one side of the treatment tank 1, and the output end of the ozone generator 19 is connected to the input end of the air pump 20 through a pipeline. The output end of the air pump 20 is fixedly connected to an air delivery pipe 21, and the top of the air delivery pipe 21 passes through the side of the treatment tank 1. The top of the air delivery pipe 21 is fixedly connected to the annular exhaust pipe 17, and the body of the air delivery pipe 21 is provided with a solenoid valve 3 22. Specifically, the air pump 20 can pump the ozone generated by the ozone generator 19 into the annular exhaust pipe 17 through the air delivery pipe 21, and then evenly discharge it into the treatment tank 1 through a plurality of exhaust ports 18, so that it evenly enters the sewage and performs catalytic oxidation treatment on the sewage;

[0026] An ozone emission pipe 23 is fixedly connected to the edge of the upper cover 10. The body of the ozone emission pipe 23 is provided with a solenoid valve 24, which can be used to discharge ozone and ensure the stability of the internal air pressure of the treatment tank 1. It should be noted that the ozone emission pipe 23 can also be connected to an ozone purification device (not shown in the figure) through a pipeline, such as an activated carbon purification device.

[0027] The use process of the utility model is as follows: the technicians in this field inject the sewage to be treated into the treatment tank 1 through the sewage inlet pipe 2. During the injection process, the sewage can be first filtered by the filter plate 14 to effectively filter out impurities in the sewage, and then the upper cover 10 is controlled by the hydraulic cylinder 7 to move down and close with the treatment tank 1 to meet the sealing requirements of the internal space of the treatment tank 1, and then the solenoid valve 24 is opened, and the ozone generator 19 and the air pump 20 are operated. The air pump 20 can pump the ozone generated by the ozone generator 19 into the annular exhaust pipe 17 through the air delivery pipe 21, and then discharge it into the treatment tank 1 evenly through a plurality of exhaust ports 18, so that it evenly enters the sewage and catalyzes the sewage. During the oxidation treatment, the technicians in this field can start the servo motor 11. When the servo motor 11 is running, the stirring paddle 13 can be driven to rotate in the treatment tank 1 through the rotating shaft 12, so that the sewage and ozone can be stirred and mixed, which is beneficial to the catalytic effect of ozone on the oxidation of sewage. After the sewage treatment is completed, the technicians in this field open the solenoid valve 2 5 to allow the treated sewage to be discharged from the treatment tank 1 through the sewage discharge pipe 4, and then operate the hydraulic cylinder 7 again to move the filter plate 14 out of the treatment tank 1. Therefore, the device can meet the sealing requirements of the internal space of the treatment tank 1 while also facilitating the removal of the filter plate 14 out of the treatment tank 1, thereby facilitating the cleaning of the clogged filter plate 14.
