摘要
近年来,微纳米气泡(MNBs)由于其具有比表面积大、水中停留时间长、气液传质效率高、Zeta电位高和能产生大量含氧活性基团等独特物理、化学特性而受到人们的广泛关注。随着对MNBs产生原因及其机理的不断研究,人们发现MNBs在环境修复、医疗、工业、农业等领域具有很好的应用潜能。文中简要介绍了MNBs强化气液传质、高Zeta电位与高稳定性、强化自由基生成等气液界面作用,并对MNBs技术在水处理、农业种植与水产养殖中的应用进行了综述,希望为其在相关领域应用提供理论和技术参考。
In recent years,micro-nano bubbles(MNBs)draw widespread attention due to the unique physical and chemical properties,such as high surface area,long residence time in water,high gas-liquid mass transfer efficiency,high Zeta potential and the ability to generate a large number of reactive oxygen species.With the continuous study of the causes and mechanisms of MNBs,it has been found that MNBs have good application potential to be applied in environmental remediation,medical treatment,industry and agriculture.In this paper,the gas-liquid interface interaction such as strengthen gas/liquid mass transfer,high Zeta potential,high stability and strengthen free radical generation are briefly introduced.This paper reviews the application of MNBs technology in the fields of water treatment,agricultural planting and aquaculture,to provide a theoretical and technical reference for the application in related fields.
