摘要
微纳米气泡具有直径小、比表面积大、水中停留时间长、气液传质效率高、界面电位高和生成自由基等特征。近年来,微纳米气泡技术在环境污染控制领域中的关注度日益增加。相对于其他处理技术,微纳米气泡技术在治理水环境污染方面具有良好的优势和巨大的发展前景。论文介绍了溶气释气法、分散空气法、电解法等主要微纳米气泡产生方法;概述了微纳米气泡在地表水治理、地下水修复、工业废水治理等水处理方面的研究和应用,最后对微纳米气泡技术进行了展望。
Micro-nano bubbles have the characteristics of small diameter,large specific surface area,long residence time in water, high gas-liquid mass transfer efficiency, high interface potential, and generation of free radicals. In recent years,the attention of micro-nano bubble technology in the field of environmental pollution control has been increasing.Compared with other treatment technologies,micro-nano bubble technology has good advantages and huge development prospects in the treatment of water environment pollution. This paper introduces the main micro-nano bubble generation methods such as dissolved gas release method,dispersed air method,and electrolytic method;summarizes the research and application of micro-nano bubbles in surface water treatment,groundwater remediation,industrial wastewater treatment. Finally,the micro-nano bubble technology was prospected.
