Abstract:
With the expeditious advancement of micro-nano bubbles technology, its amalgamation with ozone oxidation has garnered considerable attention. Micro-nano bubbles are renowned for their inherent advantages in augmenting gas-liquid mass transfer efficacy and the spontaneous generation of hydroxyl radicals. Moreover, their combined employment with ozone yields significant improvements in both ozone mass transfer and oxidation, while also synergistically enhancing ozone catalytic oxidation. By conducting a comprehensive analysis of the distinctive characteristics and generation modality of micro-nano bubbles, scrutinizing the mechanism and influencing factors governing the degradation of organic matter via ozone micro-nano bubbles technology, and delving into the application of this technology in organic wastewater treatment, the advantages and limitations of ozone micro-nano bubbles technology have been elucidated, thereby furnishing a reference for the dissemination and implementation of this technology.
