[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 4As shown, the utility model provides a technical solution: a chemical wastewater treatment device based on ozone catalytic oxidation, comprising: a treatment mechanism 1, a guide mechanism 2 is arranged on one side of the treatment mechanism 1, the treatment mechanism 1 comprises a cavity 11, a reaction tank 17 is opened inside the cavity 11, a roller 18 is arranged on the inner surface of the reaction tank 17, the inner surface of the reaction tank 17 is rotatably connected to one end of the roller 18, a motor 19 is arranged on the other end of the roller 18, the other end of the roller 18 is fixedly connected to the output end of the motor 19, one end of the motor 19 is fixedly connected to one side of the cavity 11, a valve 110 is arranged on one side of the cavity 11, one side of the cavity 11 is fixedly connected with one end of the valve 110, a diverter plate 12 is arranged on the top of the cavity 11, the top of the cavity 11 is fixedly connected to the bottom of the diverter plate 12, and an ozone generator 13 and an oxidizer 1 are arranged on the top of the diverter plate 12 respectively. 4. The top of the diverter plate 12 is fixedly connected to the bottom of the ozone generator 13 and the oxidizer 14. Two guide plates 15 are provided at the bottom of the diverter plate 12. Catalyst reactor 16 is provided at one end of the two guide plates 15. One end of the two guide plates 15 is fixedly connected to one side of the catalyst reactor 16. The bottom end of the catalyst reactor 16 is located inside the reaction tank 17. A water pump 113 is provided at the top of the cavity 11. The top of the cavity 11 is fixedly connected to one end of the water pump 113. A waste water tank 114 is provided at the other end of the water pump 113. The other end of the water pump 113 is fixedly connected to one side of the waste water tank 114. One end of the bottom of the waste water tank 114 is fixedly connected to one side of the cavity 11. A detection plate 111 is provided at one end of the valve 110. One end of the valve 110 is located above the detection plate 111. One side of the detection plate 111 is slidably connected to the inner surface of the detection table 112.

[0026] In this embodiment, when the device is in use, the ozone generator 13 and the oxidizer 14 are started at the same time, so that the airflows of the two enter the diverter plate 12 at the same time, and the airflow enters the guide plate 15 along the internal channel, and the guide plate 15 introduces the gas into the catalyst reactor 16. This uniform design can ensure that the airflow in the reactor is evenly distributed, avoiding the problem of airflow dead corners or insufficient reaction. Ozone is a strong oxidant, which can accelerate the oxidation reaction after combining with the oxidant. After being introduced into the catalyst reactor 16, the catalyst can further reduce the activation energy of the reaction, thereby accelerating the oxidation process. At this time, after passing through the chemical reactor, the gas will enter the reaction tank 17, and then the wastewater tank 114 is introduced into the reaction tank 17 through the water pump 113, so that the wastewater and the gas merge, and then the motor 19 is started to make the roller 18 start to rotate in the reaction tank 17, which can increase the contact surface area between the gas and the wastewater, accelerate the removal or degradation process of pollutants, and thus improve the purification efficiency.

[0027] Secondly, after treatment, a portion of the wastewater is allowed to flow into the detection plate 111 by opening the valve 110, and then the water quality is tested by the detection table 112, and a detailed water quality analysis is performed to ensure that the treated wastewater meets the discharge standards or quality requirements. If the water quality does not meet the requirements, the operator can take appropriate measures to adjust the treatment system to ensure that the wastewater meets the compliance standards before discharge.

[0028] Example 2

[0029] like Figure 1 - Figure 4 As shown, the guide mechanism 2 includes a guide rail 21, a roller 23 is provided on the inner surface of the guide rail 21, the inner surface of the guide rail 21 is in contact with the outer side of the roller 23, a fixing plate 22 is provided at one end of the roller 23, one end of the roller 23 is movably connected to the inner wall of the fixing plate 22, a detection platform 112 is provided on the top of the fixing plate 22, the top of the fixing plate 22 is fixedly connected to the bottom end of the detection platform 112, and one side of the guide rail 21 is fixedly connected to one end of the bottom of the cavity 11.

[0030] In this embodiment, the detection platform 112 is pushed on the fixed plate 22 so that it is no longer located at the front end of the valve 110 to prevent it from affecting the water quality discharge. During the pushing process, a roller 23 is installed on the fixed plate 22. The existence of the roller 23 can enable the detection platform 112 to be pushed smoothly on the fixed plate 22. By reducing the friction, the roller 23 can make the moving process smoother. Moreover, through the roller 23, the position of the detection platform 112 can be relatively easily adjusted to adapt to different operating requirements, which helps to quickly move the detection equipment when needed without affecting the operation of the entire wastewater treatment system.

[0031] Working principle:

[0032] like Figure 1 - Figure 4 As shown, by starting the ozone generator 13 and the oxidizer 14 at the same time, the gas is introduced into the catalyst reactor 16. After being introduced into the catalyst reactor 16, the catalyst can further reduce the activation energy of the reaction, thereby accelerating the oxidation process. At this time, after passing through the chemical reactor, the gas will enter the reaction tank 17. Then, the wastewater tank 114 is introduced into the reaction tank 17 through the water pump 113, so that the wastewater and the gas merge. Then, by starting the motor 19, the roller 18 starts to rotate in the reaction tank 17, which can increase the contact surface area between the gas and the wastewater and accelerate the removal or degradation process of the pollutants. Secondly, by opening the valve 110, a part of the wastewater flows into the detection plate 111, and then the water quality is detected by the detection table 112, and a detailed water quality analysis is performed to ensure that the treated wastewater meets the discharge standard or quality requirements.

[0033] Pushing the detection platform 112 on the fixed plate 22 so that it is not located at the front end of the valve 110 can ensure that after the wastewater is treated, the discharge of water quality will not be affected by the influence of the detection equipment. The fixed plate 22 is equipped with a roller 23. The existence of the roller 23 can make the detection platform 112 smoothly pushed on the fixed plate 22. By reducing friction, the roller 23 can make the moving process smoother.
