微纳米气泡的Zeta电位在水处理领域的应用
Application of Zeta potential of micro-nano bubbles in water treatment field
摘要
Abstract
In recent years,micro-nano bubbles technology has been investigated by researchers in environmental science and water treatment.Compared to conventional ozone-based advanced oxidation technology,the advantages of micro-nano bubbles are demonstrated through high oxidation efficiency,low energy consumption,and the absence of secondary pollution.These advantages are primarily attributed to the unique physicochemical properties of micro-nano bubbles,such as a large specific surface area,prolonged residence time,high mass transfer efficiency,and elevated interfacial Zeta(ζ)potential.The interface ζ potential is closely related to the stability of bubbles in water and the interaction with pollutants.When the absolute value of the ζ potential is maintained at a high level,several enhanced properties are observed,including dispersibility improvement,strong adsorption capacity,high oxygenation efficiency,and ozone-enhanced oxidation effects.In this paper,the fundamental characteristics of micro-nano bubbles,the concept of ζ potential,and three ζ potential detection methods(electrophoresis,streaming potential,and electroacoustic techniques)are systematically introduced.Furthermore,the application scope,advantages,and limitations of these detection methods are analyzed to evaluate their practical utility.The application potential of micro-nano bubbles is discussed in the context of air flotation processes,water body restoration,and industrial wastewater treatment.This analysis is regarded as providing critical guidance for both theoretical research and practical implementation,particularly in achieving precise control of ζ potential to address diverse water quality conditions.关键词
