The development of new disinfection treatment by ozone microbubbles generated from hollow ultrasonic horn

利用空心超声变幅杆产生的臭氧微泡对水进行消毒处理，并对其杀灭水中大肠杆菌的能力进行了评价。通过使用由中空超声变幅杆产生的臭氧微泡、由具有超声照射的分散器产生的臭氧气泡以及在相同的臭氧气体供应条件下由分散器产生的臭氧气泡的消毒处理完全灭菌所需的时间分别为15、27和30分钟，这表明具有超声照射的臭氧鼓泡增强了消毒。

Water disinfection treatment using ozone microbubbles generated by a hollow ultrasonic horn was developed, and its ability to inactive Escherichia coli in water was evaluated. The times required for complete sterilization by the disinfection treatment with ozone microbubbles generated by the hollow ultrasonic horn, ozone bubbles generated by a disperser with ultrasonic irradiation, and ozone bubbles generated by a disperser under the same ozone gas supply conditions were 15, 27, and 30 min respectively, which indicates that ozone bubbling with ultrasonic irradiation enhances disinfection.
