微纳米气泡光学观测系统开发

Development of optical observation system for micro-nano bubbles

微纳米气泡技术在污染的地下水原位修复领域具有巨大的应用潜力。设计了一套微纳米气泡的光学观测系统,该系统由模型箱、激光器、CCD相机、显微镜头、三维可调节支架及图像处理软件组成,可以对微纳米气泡在水体中及多孔介质中的粒径分布、运动速度和吸附特性等进行观测,并分析其影响因素。该系统观测的微纳米气泡粒径范围为900nm以上。该系统功能强、观测精度高,在实际教学和科研中发挥了重要作用。

The micro-nano bubbles technology has potential use for remediation of contaminated groundwater . However ,the physical properties of micro-nano bubbles in water and porous media have not been investigated comprehensively so far . an optical observation system including model box , laser device , CCD camera , microscopic lens , adjustable holder and post-processing software is designed for imaging the bubble size distribution ,velocity and adsorption of micro-nano bubbles （＆gt; 900 nm） in water and porous media .This optical system is advanced ,functional and accurate ,playing an important role in teaching and researching .
