摘　　要：目的 :了解经 YJX- 型活氧消毒杀菌器制成臭氧水的杀菌效果。方法 :开机工作 2 0 min,臭氧水浓度达稳定值后 ,进行试验。结果 :自然条件下 ,该臭氧水经过 2 0 min,自然降解 5 0 %左右。含臭氧浓度为 0 .5 6 m g/ L 的该臭氧水对大肠杆菌作用 1min,对金黄色葡萄球菌作用 5 min,杀灭率均达 10 0 %。用苹果作现场应用试验 ,作用 15 m in,自然菌杀灭率达 98.0 %。结论Objective:To acknowledge the germicidal efficacy of ozone water.Method:Test was carried out after 20 minutes.Results:The ozone water which ozone conceration was 0 56mg/L could kill 100% of escherichia coli with 1min,and kill 100% of staphylococus aureus with 5min.Natural bacteria was killed at 92 7% at the test which immersion of apples in this ozone water after 10min.Conclusion:Germicidal efficacy and stability of ozone water are good.
