摘要
微纳米气泡(MNBs)具有尺寸小、比表面积大、水中停留时间长、Zeta电位高、氧化性强、传质效率高、生物活性强、无二次污染等特性,相比传统的宏观气泡,具有更高效的修复环境水体的性能。在分析国内外已有的研究基础上,就气泡分类和产生方式的研究进行介绍;详细探讨了MNBs的优良特性及不同因素对其特性的影响;分析了MNBs在水体和多孔介质中的运移规律和受控因素,重点阐明了MNBs修复环境水体的作用机理;系统评述了MNBs在环境水体修复中的研究进展,重点介绍了臭氧MNBs的应用前景,并对MNBs在环境水体修复的后续研究方向进行了展望。
Micro-nano bubbles(MNBs)are more energy-efficient than traditional macro bubbles in terms of environmental water remediation because of their perfect characteristics,such as small dimension,large specific surface area,long residence time in water,high Zeta potential,strong oxidization,high mass transfer efficiency,enhancement in biological activity,and no secondary pollution.Based on the analysis of existing researches,first,the bubble classification and generation method are introduced.Next,the excellent characteristics of MNBs and the corresponding influencing factors are discussed in detail.Subsequently,the migration regulation and controlled factors of MNBs in water and porous media are analyzed,focusing on the mechanism of MNBs in remediating environmental water.Finally,a systematic review of the current status of the research on MNBs and the application in environmental water remediation is evaluated,with the promising application prospects of ozone MNBs as the priority.The future research directions of MNBs in environmental water remediation are discussed as well.
