Abstract

In comparison with traditional bubbles, micro-nano bubbles (MNBs) could generate hydroxyl radical(·OH) and owned advantages of large specific surface area, high gas-liquid mass transfer efficiency, high zeta potential at the bubble interface, easy self-pressurization and collapse, and they have been widely used in environmental engineering. This paper summarized the formation mechanisms of the ·OH generated by MNBs and its influencing factors. The application of the produced ·OH in water and wastewater treatment was briefly introduced. In addition, the development direction and application of MNBs are prospected, which are promising to provide reference for the theoretical research and practical application of micro nano bubble technology.
