Description

Technical field [0001] The present invention belongs to the field of wastewater treatment, and is specifically a hydraulic-ultrasonic airborne synergistic swirling microbubbles to strengthen ozone mass mass and produce a more hydroxyl radical device. Background technique [0002] In recent years, with the rapid development of coking, pharmaceutical, petrochemical, printing and dyeing, chemical and other industries, the ecological issues that have all kinds of wastewater that are difficult to degrade organic matter have become more serious. Most of these wastewater contain a polycyclic aromatic hydrocarbon, a halogenated hydrocarbon, a heterocyclic compound, an organic pesticide, and the like to poisonous organic pollutants. These pollutants are complex and toxic. Once the discharge of the environment will have a great influence on the ecological environment and human health. However, traditional biochemical methods are difficult to deal with these difficult to degrade organics. ...

AI Technical Summary

Problems solved by technology

In recent years, the application of ozone-microbubble technology, ozone-hydraulic cavitation technology and ozone-ultrasonic cavitation technology in water treatment has been extensively studied, but the mass transfer efficiency of ozone and the generation of hydroxyl radicals need to be improved. Therefore, it is necessary to provide a device that generates a large amount of strong oxidizing hydroxyl radicals while enhancing ozone mass transfer, thereby improving the utilization rate of ozone and effectively degrading refractory organic matter, expanding the application range of the ozone oxidation process
