Abstract:

Micro-nano bubbles have unique physical and chemical properties and can form a synergistic coupling effect with traditional water treatment technologies, making them a green and efficient way for technological iteration and upgrading. Compared to ordinary bubbles, micro-nano bubbles have larger specific surface area and longer hydraulic retention time, which helps to expand the gas-liquid contact area and enhance the mass transfer efficiency. Their abundant surface charges can also promote the generation of reactive oxygen species, promoting the degradation of organic pollutants. The generation methods, common characterization techniques, and visualization methods of micro-nano bubbles were summarized. The research progress and application practices of micro-mano bubbles in water treatment processes were reviewed. The mechanism and influencing factors of micro-nano bubbles enhanced water treatment technology were systematically analyzed. The significant advantages of micro-nano bubbles arisen from their unique physicochemical properties were emphasized, especially in enhancing biochemical, physical-chemical, and membrane treatment processes. Furthermore, it was pointed out that there were still limitations in the continued in-depth research and expanded application of current micro-nano bubble technology. The key research directions for the innovation and upgrading of micro-nano bubbles in water treatment technology were also discussed.

Key words: micro-nano bubbles, water treatment, mass transfer, gas-liquid interface, technology retrofitting
