微气泡发生及其在危化品气浮处置中的应用进展
Progress of Microbubble Generation and Its Application in the Flotation Disposal of Hazardous Chemicals
摘要
Abstract
Microbubbles have important research and application value in chemical industry,medicine,en-vironment and other fields because of their large specific surface area,long residence time and high reaction ef-ficiency.At present,the generation methods of microbubbles are various,and the methods used in different fields are not the same.Firstly,a variety of microbubble generation methods,including direct aeration method,dissolved gas release method,liquid phase shear method,etc.,were reviewed,the generation mechanism and prediction model of different microbubble generators were described,and the diameter range of microbubbles generated by each method was compared.Then,in terms of enhanced air flotation disposal of hazardous chemi-cals in water by microbubbles,compared with the traditional air flotation method,it was pointed out that the modified bubble air flotation method can reduce the net negative charge on the surface of the bubbles or reverse its charge to positive,thereby improving the electrostatic interaction between bubbles and hazardous chemicals particles/droplets in water and strengthening the collision adhesion effect between them.Thus,it can essentially improve the efficiency of air flotation disposal.Finally,the next research direction was analyzed and prospec-ted,and it was pointed out that in order to improve the industrial application of microbubbles,the structural modification of microbubble generator and the interface regulation mechanism of bubbles will be the focus of subsequent research.关键词
