摘要
目的:观察臭氧水消毒器产生臭氧水的杀菌效果。方法:采用悬液定量和载体定量杀菌试验进行检测。结果:该机产生含臭氧4.20 mg/L的水溶液对大肠杆菌、金黄色葡萄球菌和白色念珠菌作用5 min的杀灭率均为100%;当菌液中含有10%蛋白胨时,对大肠杆菌、金黄色葡萄球菌和白色念珠菌作用5 min的杀灭率分别为55.67%、59.48%和37.44%。用消毒液流动浸泡载体定量杀菌试验,含臭氧4.20 mg/L的水溶液作用30 min对大肠杆菌、金黄色葡萄球菌和白色念珠菌的平均杀灭率分别为99.95%、99.99%和96.94%。结论:该臭氧水消毒器产生的臭氧水具有一定消毒效果。
Objective： To observe the germicidal efficacy of the ozone water generated by Ozone Water disinfector. Method： suspension quantitative and carrier quantitative germicidal tests were used for examination. Result： The results showed that the ozone water containing ozone 4.20 mg/L generated by the disinfector killed 100% of Escherichia coli, Staphylococcus aureus and Candida albicans after 5 minutes. If peptone exposure 10 g/L was in suspension, the killing rates of Escherichia coli, Staphylococcus aureus and Candida albicarL,, after 5 minutes exposure were 55.67 %, 59.48 % and 37.44 % respectively. When quantitative germicidal test method using carriers irranersed in running liquid disinfectant was used, the ozone water containing ozone 4.20 mg/L killed 99.95%, 99.99% and 96.94% of Escherichia coli, Staphylococcus aureus and Candida albicans in average after 30 minutes. Conclusion： The results suggest that the ozone water generated by Ozone Water Disinfector had disinfection effect.
