Abstract

Abstract : Owing to some advantages of high oxidation capacity, high mass‐transfer efficiency, high utilisation rate of reagents, simple system for treating pollutants, micro–nanobubble technology (MNBT) has gradually attracted attention and has been successfully applied in environmental pollution control. Currently, its applications in this field are mainly in the aspects of surface water purification, sewage (waste) water treatment, soil and groundwater remediation and sludge treatment which are reviewed. These studies primarily focus on the MNB generation (MNBG) methods, the parameters of pollution treatment and its effect improvement, the coupling techniques of this technology and other advanced oxidation technologies. However, in order to successfully promote its applications to the actual environmental pollution control process, especially the industrial scale, the following efforts are required: covariant response mechanism of water quality – micro–nano aeration parameters – bubble characteristics, further optimisation of synergistic process with other advanced oxidation methods, development of lower energy consumption and more efficient MNBG devices. After discussion and analysis, this work further points out that the purification of exhaust gas such as volatile organic compounds (VOC) and flue gas is one of the research directions worth exploring in the future application of the MNBT.
