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

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-salt organic wastewater ozone catalytic oxidation system, including an ozone generator 1 and an ozone oxidation tank 12 assembled on one side of the ozone generator 1. A rotameter 2 is installed on one side of the ozone generator 1, an ozone concentration monitor 3 is installed on one side of the rotameter 2, a three-way pipe 4 is connected to one side of the ozone concentration monitor 3, the rear end of the three-way pipe 4 is connected to an air pump 7, a filter mechanism 6 is installed on one side of the three-way pipe 4, and a first solenoid valve 5 is installed at the connection of the three-way pipe 4 with the ozone concentration monitor 3 and the filter mechanism 6. One side of the air pump 7 is respectively connected with a first aeration pipe 10 and a second aeration pipe 11 which are staggered through a shunt pipe 8. One side of the first aeration pipe 10 and the second aeration pipe 11 extends into the ozone oxidation tank 12. A second solenoid valve 9 is installed on the periphery of the shunt pipe 8, and an ozone catalyst 13 is installed inside the ozone oxidation tank 12 at the top of the first aeration pipe 10 and the second aeration pipe 11.

[0022] Based on the above structure settings, the ozone catalytic oxidation system for high-salt organic wastewater consists of an ozone generator 1 and an ozone oxidation tank 12. Among them, the ozone generator 1 is used to provide ozone for the treatment of high-salt organic wastewater, and the ozone oxidation tank 12 is used to provide a container for the high-salt organic wastewater to be treated. The first solenoid valve 5 on the side of the tee 4 close to the filtration mechanism 6 is a normally closed valve, and the first solenoid valve 5 on the side close to the ozone concentration monitor 3 is a normally open valve. Specifically, during the working process, the high-salt organic wastewater to be treated is added into the ozone oxidation tank 12, the ozone generator 1 and the air pump 7 are started, and the air pump 7 transmits the ozone generated by the ozone generator 1 to the inside of the first air diffuser pipe 10 or the second air diffuser pipe 11 through the shunt pipe 8. By controlling the second solenoid valve 9, the gas transmitted by the air pump 7 can be guided into the first air diffuser pipe 10 or the second air diffuser pipe 11, thereby promoting the contact between ozone and high-salt organic wastewater, and realizing the treatment of high-salt organic wastewater in cooperation with the ozone catalyst 13. The rotor flowmeter 2 can be used to detect the flow rate of ozone transmission, and the ozone concentration monitor 3 can be used to detect the concentration of ozone. When the first solenoid valve 5 on the side close to the ozone concentration monitor 3 is closed and the first solenoid valve 5 on the side close to the filtration mechanism 6 is opened, after the air pump 7 operates, the filtration mechanism 6 is used to transmit external gas into the ozone oxidation tank 12 to aerate the high-salt organic wastewater to meet different treatment requirements. The ozone catalytic oxidation system for high-salt organic wastewater is equipped with the first solenoid valve 5. During use, by controlling the first solenoid valve 5, the gas transmitted by the air pump 7 can be controlled according to the treatment requirements after control, improving the effect of aeration treatment. The second solenoid valve 9 can be used to control the flow of the gas transmitted by the shunt pipe 8, and the first air diffuser pipe 10 and the second air diffuser pipe 11 at different positions can be used to treat the wastewater at different positions in the ozone oxidation tank 12, optimizing the use process.

The filter box 601 is installed on one side of the tee 4, and the filter element 603 is detachably installed at the front end of the filter box 601. Among them, air guide holes are opened inside the filter box 601, and the rear end of the filter element 603 is inserted into the air guide holes. Specifically, the filter box 601 can be used to guide the gas during use, and the filter element 603 can be used to filter the impurities in the gas entering the filter box 601, improving the cleanliness of the gas.

[0024] Furthermore, the filtration mechanism 6 further includes an air inlet window 602, and the air inlet window 602 is opened on the top of the filter box 601. Among them, air filter mesh holes are opened on the air inlet window 602. Specifically, the air inlet window 602 can be used to filter the impurities in the gas entering the filtration mechanism 6 during use, preventing the impurities doped in the air from entering the air pump 7.

[0025] Furthermore, a detachable end cover 15 is installed on the top of the ozone oxidation tank 12, and an exhaust gas discharge pipe 16 is installed on the top of the end cover 15. Among them, an exhaust cavity is provided inside the exhaust gas discharge pipe 16 and the end cover 15; specifically, the end cover 15 can be used to shield and protect the top of the ozone oxidation tank 12, and the exhaust gas discharge pipe 16 can be used to guide and discharge the ozone exhaust gas inside the ozone oxidation tank 12.

[0026] Furthermore, a drain pipe 14 is installed on one side of the ozone oxidation tank 12, and the vertical plane of the drain pipe 14 is higher than that of the ozone catalyst 13. Specifically, the drain pipe 14 can be used to discharge the wastewater treated by the ozone catalyst 13 from the inside of the ozone oxidation tank 12 during use, so as to realize the treatment of high-salt organic wastewater.
