Advanced oxidation effect of the disinfection system using ultrasonically-generated ozone microbubbles

我们开发了一种利用中空超声喇叭产生臭氧微泡的水消毒处理方法，并研究了这种处理对大肠杆菌的灭活效果。实验结果表明，这种处理涉及大肠杆菌的有效消毒。利用中空超声喇叭产生的臭氧微泡进行处理，由于微泡的高溶解度以及臭氧和超声波辐照的协同作用，即增强臭氧的自分解和自由基的产生，导致了有效的消毒。

We developed a water disinfection treatment approach using ozone microbubbles generated by a hollow ultrasonic horn, and investigated the effect of inactivation for Escherichia coli with this treatment. Experimental results reveal that this treatment involves efficient disinfection of Escherichia coli. This treatment using ozone microbubbles generated by a hollow ultrasonic horn led to efficient disinfection, owing to the high solubility of the microbubbles and the synergism of the ozone and ultrasonic irradiation, i.e. the enhancement of ozone self-decomposition and radicals generation.
