Abstract:
Objective To assess the role of various factors in the sterilization effect of ozone in water and provide the basic data for the correct use of ozone generator. Methods E.coli 8099 was employed as the indicative bacteria. The effect of killing E.coli 8099 by ozone in water was detected under various conditions,such as temperature,pH value,flux. Results The inactivated rates of indicative bacteria were 99.99%～100% by ozone in five minutes under the basic condition of 20 ℃,pH=7.0 and ozone flow of 1 L/min. The bactericidal effect was relatively better at low temperature and low pH value,the high flow of ozone led low sterilization effect of ozone. Conclusion High temperature,higher pH value,higher flow is not conducive for ozone to be dissolved in water,thereby will affect the bactericidal effects of ozone.
