[0002] my country is an industrial power, and it produces a large amount of difficult-to-treat high-salt wastewater every year. High-salt wastewater is wastewater with a total salt content of at least 1%, which is mainly produced in different industrial production processes such as petrochemicals, coal chemical industry, textiles, leather and pharmaceuticals. High-salt wastewater contains a large amount of free inorganic ions, such as Na + , K + , Ca 2+ 、SO4 2- 、Cl - 、CO3 2- It has the characteristics of high salt concentration, high osmotic pressure, and high total dissolved solids content. Therefore, the difficulty of this wastewater treatment technology is much higher than that of ordinary sewage treatment.

[0003] The direct discharge of high-salinity wastewater not only wastes water resources but also poses significant environmental risks. High-salinity wastewater can severely damage soil ecology, harm crops, and even threaten food production, hindering economic development. It can also pollute rivers and groundwater, severely harming aquatic life, deteriorating the water environment, and posing a potential threat to drinking water safety.

[0004] Currently, Fenton oxidation and ozone oxidation technologies are more commonly used in the treatment of high-salt wastewater.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] See also Figure 1 The figure shows a high-salt wastewater treatment device, which includes a reaction container 100, a high-pressure pump 200, an atomizing tube 300, an ultraviolet lamp 400, an ozone generator 500, an ozone inlet pipe 600 and an exhaust gas processor 700.

[0025] The reaction vessel 100 is a rectangular closed structure with an air outlet 110 on the top and a water outlet 120 on the bottom. An observation window 130 is provided on the side of the reaction vessel 100 to facilitate staff to observe the reaction status inside the reaction vessel 100.

[0026] The water inlet end of the high-pressure pump 200 is connected to the water outlet of the sewage pool 10 through the water inlet pipe 210. It is used to pressurize the high-salt wastewater flowing out of the sewage pool 10 to improve the atomization effect.

[0027] One end of the atomizing tube 300 is connected to the water outlet of the high-pressure pump 200, and the other end extends into the reaction vessel 100 and is located at the top of the reaction vessel 100. The atomizing tube 300 is located within the reaction vessel 100 and has a plurality of atomizing nozzles 310 spaced along its length. This utility model uses the high-pressure pump 200 to atomize high-salt wastewater into the reaction vessel 100, effectively increasing the contact area and reaction time.

[0028] The UV lamp 400 is disposed in the reaction vessel 100 and is located at the center of the reaction vessel 100. A transparent protective sleeve 410 is sleeved on the outer periphery of the UV lamp 400 to protect the UV lamp 400. In this embodiment, the transparent protective sleeve 410 is a quartz sleeve.

[0029] The ozone generator 500 is located outside the reaction vessel 100 and is used to generate ozone. One end of the ozone inlet pipe 600 is connected to the outlet of the ozone generator 500, while the other end extends into the reaction vessel 100 and is located at the bottom of the reaction vessel 100. The ozone inlet pipe 600, located within the reaction vessel 100, has several microporous aeration tubes 610 spaced along its length.

[0030] The tail gas processor 700 is disposed on the top surface of the reaction vessel 100 and is located at the gas outlet 110 of the reaction vessel 100. In this embodiment, the tail gas processor 700 is preferably a 3S-W2 tail gas processor manufactured by Shanghai Tonglin Technology Co., Ltd.

[0031] This utility model uses a high-pressure pump 200 to atomize high-salinity wastewater from a sewage tank 10 and introduce it into a reaction vessel 100, effectively increasing the contact area and reaction time of the high-salinity wastewater. A UV lamp 400, placed in the center of the reactor, then performs advanced oxidation treatment on the atomized droplets. Simultaneously, ozone generated by an ozone generator 500 is introduced into the reaction vessel 100 via an ozone inlet pipe 600 and a microporous aeration short tube 610 at the bottom, synergizing with the UV light to treat the wastewater. Both ozone and UV technologies are advanced oxidation technologies, primarily utilizing light, electricity, and catalysts to generate highly oxidizing free radicals (such as OH) during the reaction process. These free radicals oxidize recalcitrant macromolecules into small molecules or directly into CO2 and H2O through bond scission and electron transfer between the free radicals and the pollutants, thereby improving the biodegradability of the wastewater.

[0032] The utility model skillfully combines ozone and ultraviolet technology, and atomizes high-salt wastewater through atomization technology, thereby increasing its contact area with ozone and ultraviolet, greatly improving the ozone utilization rate, and can effectively remove difficult-to-degrade organic matter in high-salt wastewater, while also achieving the purpose of disinfection and sterilization.
