摘　　要：微纳米气泡的出现及其不同于普通气泡的特点,使其在水处理等领域显现出优良的技术优势和应用前景。介绍了微纳米气泡以及其比表面积大、停留时间长、自身增压溶解、界面ζ电位高、产生自由基、强化传质效率等特点,论述了微纳米气泡在水体增氧、气浮工艺、强化臭氧化、增强生物活性等环境污染控制领域的应用研究。之后重点阐述了微纳米气泡发生装置及其发生机理,提出开发结构简单、能耗更低、性能更优的发生装置是微纳米气泡技术未来研究的重点。The appearance of micro-nano bubble and its characteristics different from the ordinary bubble make it show better technical superiority and application prospect. The concept of micro-nano bubble and its traits,including larger specific surface,longer residence time,pressurized dissolution,higher ζ potential,free radical generation and higher mass transfer efficiency were introduced in this paper. The research of micro-nano bubble applied in environmental pollution control such as water aeration,floatation,enhancing ozonation and increasing bioactivity were also described. Then,based on the discussing on the micro-nano bubble generator and its working mechanism,the advantages and disadvantages of micro-nano bubble generator were described. It was proposed that simpler structure,lower energy consumption and better performance generator was the key direction of future research on micro-nano bubble technology.
