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

研究了利用中空超声喇叭产生的臭氧微泡对水体进行消毒处理，并对其灭活水中大肠杆菌的能力进行了评价。在相同的臭氧供气条件下，空心超声喇叭产生的臭氧微泡、超声辐照下分散器产生的臭氧泡和分散器产生的臭氧泡消毒处理完全灭菌所需的时间分别为15、27和30 min，说明超声辐照下臭氧鼓泡增强了消毒效果。

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.
