[0021] The present invention provides a catalytic oxidation treatment device. Figure 1-4As shown, the catalytic oxidation treatment device includes: a base 1; a first treatment tank 2, which is installed on the top of the base 1; a second treatment tank 3, which is installed on the top of the base 1 and connected to the first treatment tank 2, and the second treatment tank 3 is used to cache sewage; a mounting cylinder 4, which is fixed on the first treatment tank 2, and a threaded connector 7 is installed on the inner thread of the mounting cylinder 4, and a sewage pipe 8 is installed on the threaded connector 7; a threaded cylinder 5, which is threadedly installed in the mounting cylinder 4, and a filter bag 6 is installed at the bottom of the threaded cylinder 5; two screens 14, which are respectively installed in the first treatment tank 2 and the second treatment tank 3; two drainage assemblies, which are both arranged on the base 1, and are used to transport sewage.
[0022] In this embodiment, the base 1 serves as the supporting structure of the entire treatment device, firmly supporting the first treatment tank 2 and the second treatment tank 3 to ensure the stable operation of the entire system. The first treatment tank 2 is the main place for catalytic oxidation treatment of sewage, and the second treatment tank 3 is mainly used to buffer the sewage or reactants discharged from the first treatment tank 2. This design helps to balance the flow rate during the entire treatment process and prevent interruptions in the treatment process. The threaded barrel 5 and the filter bag 6 can play a role in preliminarily filtering solid pollutants in the sewage. When the filter bag 6 is blocked, it can be easily removed for cleaning or replacement by rotating the threaded barrel 5, which greatly improves the cleaning convenience and operating efficiency of the device. The screen 14 further intercepts and collects solid particles in the sewage to prevent them from entering subsequent treatment processes or causing pipeline blockage, thereby ensuring the smooth operation of the entire treatment system.
[0023] In a further preferred embodiment of the present invention, the drainage assembly includes a second water pump 15, a third water pump 16, two connecting pipes 17 and two drainage pipes 22, the second water pump 15 and the third water pump 16 are both installed on the base 1, the two connecting pipes 17 are respectively fixed at the drainage ends of the second water pump 15 and the third water pump 16, the two connecting pipes 17 extend into the first treatment tank 2 and the second treatment tank 3, respectively, the two drainage pipes 22 are respectively installed at the drainage ends of the second water pump 15 and the third water pump 16, and any one of the drainage pipes 22 extends into the second treatment tank 3.
[0024] In this embodiment, the second water pump 15 and the third water pump 16 serve as the core power sources of the drainage component. They can work separately or simultaneously to extract the sewage or reactants in the first treatment tank 2 and the second treatment tank 3 according to actual needs, and transport them to subsequent treatment stages or designated locations. The connecting pipe 17 serves as a bridge between the water pump and the treatment tank, ensuring that the sewage or reactants can be smoothly extracted from the treatment tank and transported to the designated location. The design of the drainage pipe 22 makes the drainage process more flexible and changeable. According to actual needs, the sewage or reactants can be discharged into the second treatment tank 3 for further treatment, or directly discharged into other treatment systems or containers.
[0025] In a further preferred embodiment of the present invention, a liquid medicine tank 9 is installed on the side of the first treatment tank 2 and the second treatment tank 3 away from each other, and a first water pump 10 is installed on the top of the two liquid medicine tanks 9. The liquid inlet ends of the two first water pumps 10 extend into the two liquid medicine tanks 9 respectively, and the liquid discharge ends of the two first water pumps 10 extend into the first treatment tank 2 and the second treatment tank 3 respectively.
[0026] In this embodiment, the medicine liquid tank 9 serves as a container for storing chemical agents, and can store different agents according to different treatment requirements. The first water pump 10 serves as a power source for adding agents, and can extract the agents from the medicine liquid tank 9 and accurately add them to the treatment tank according to a preset program or operating instruction. This design realizes the automation and precise control of agent addition, improves the efficiency and effect of sewage treatment, and enhances the targetedness of sewage treatment. By adding different chemical agents, different types of pollutants can be specially treated, which improves the targetedness and effectiveness of sewage treatment. The automated addition of agents reduces the tediousness and errors of manual operation, and improves the automation level and operating efficiency of the entire treatment system.
[0027] In a further preferred embodiment of the present invention, the first treatment tank 2 and the second treatment tank 3 are both equipped with exhaust pipes 11 for discharging waste gas, the tops of the two liquid medicine tanks 9 are both equipped with liquid replenishing pipes, and the two liquid replenishing pipes are both equipped with protective covers.
[0028] In this embodiment, the exhaust pipe 11 is used to discharge the waste gas generated during the treatment process, ensure the stability of the gas environment in the treatment tank, and prevent harmful gases from causing harm to the environment and personnel. The rehydration tube serves as a channel for replenishing chemical agents into the liquid medicine tank 9, ensuring a continuous supply and sufficient reserve of agents. The protective cover plays a role in preventing dust, pollution and misoperation, ensuring the cleanliness and safety of the agents.
[0029] In a further preferred embodiment of the present invention, a stirring rod 13 is rotatably installed in the first treatment tank 2 and the second treatment tank 3, and a support frame 12 is fixed in the first treatment tank 2 and the second treatment tank 3.

[0030] In this embodiment, the main function of the stirring rod 13 is to mix the sewage and the chemical catalyst to ensure that the two are in full contact and a chemical reaction occurs. By stirring, the reaction rate can be accelerated, the treatment efficiency can be improved, and the treatment effect can be made more uniform and thorough. The motor serves as the power source of the stirring rod 13, and the mixing of sewage and the agent is achieved by driving the stirring rod 13 to rotate. The decontamination port 19 is used to discharge solid pollutants or sediments generated during the treatment process to keep the treatment tank clean and running smoothly. By regularly cleaning the decontamination port 19, excessive accumulation of pollutants can be prevented, resulting in a decline in treatment effect or equipment failure.
[0031] In a further preferred embodiment of the present invention, baffles 20 are installed on the first treatment tank 2 and the second treatment tank 3 by bolts, and the two baffles 20 respectively cover the two decontamination ports 19, and sealing rings are installed on the two baffles 20, and the two sealing rings respectively surround the outside of the two decontamination ports 19.
[0032] In this embodiment, the main function of the baffle 20 is to close the sewage removal port 19 to prevent sewage or solid pollutants from overflowing or leaking from the sewage removal port 19 during the treatment process. By fixing with bolts, the baffle 20 can be firmly installed on the treatment tank to ensure the reliability of the sealing effect. The sealing ring, as a key component to enhance the sealing performance, can effectively fill the tiny gap between the baffle 20 and the sewage removal port 19 to prevent the leakage of gas, liquid or solid particles.
[0033] In a further preferred embodiment of the present invention, handles 21 are installed on both baffles 20 , observation windows are provided on both the first treatment tank 2 and the second treatment tank 3 , and valves 18 are provided on both connecting pipes 17 .
[0034] In this embodiment, the design of the handle 21 allows the operator to easily apply force when opening or closing the baffle 20, reducing the difficulty of operation and labor intensity, and also increasing the safety of the baffle 20, preventing accidents such as scratches or burns caused by direct contact with the baffle 20. The observation window allows the operator to directly observe the sewage treatment status in the tank without opening the treatment tank, including the reaction status, sewage color changes, solid pollutant precipitation, etc. This real-time monitoring capability helps the operator to adjust the treatment parameters or take necessary treatment measures in time to ensure the effectiveness and stability of sewage treatment. The valve 18, as a key component for controlling fluid flow, can open or close the connecting pipe 17 as needed to achieve precise control of sewage or chemical catalysts.
[0035] To sum up, compared with the relevant technology, this device can mix different chemical reactants in sewage under different environments by setting up the first treatment tank 2 and the second treatment tank 3. There is no need to wait for one reaction to be completed before adding another reactant, and then wait for the time required for a reaction, thereby increasing the catalytic oxidation efficiency of sewage. By setting a motor to drive the stirring rod 13 to rotate, the sewage and the reactants can be fully mixed, thereby increasing the reaction efficiency. By setting the sewage removal port 19 and closing the sewage removal port 19 through the baffle 20, it is convenient for personnel to handle the solid pollutants in the two treatment tanks, and the sewage can be preliminarily filtered through the filter bag 6.
