采用悬液定量杀菌和流动杀菌的方法，对铜绿假单胞菌（Pseudomonas aeruginosa)、粪链球菌（Strep-tococcus faecium)和大肠杆菌（Escherichia coli)的臭氧消毒效果进行了研究。结果表明，悬液定量杀菌试验中，臭氧浓度0.36 mg/L，作用10 min后，铜绿假单胞菌存活率小于1.0%；臭氧浓度0.31 mg/L，作用3 min后，粪链球菌存活率小于0.1%；臭氧浓度在0.45 mg/L及以上，作用10 min后，大肠杆菌存活率在2.0%以下。流动杀菌试验中，臭氧浓度0.20~0.60 mg/L，作用3 min后，大肠杆菌、铜绿假单胞菌和粪链球菌的存活率在0.01%以下，即杀灭率在99.99%以上。

Both suspension quantitative germicidal test and flow germicidal test were used to study disinfection effects of ozone on the Pseudomonas aeruginosa, Streptococcus faecium and Escherichia coli. The suspension quantitative germicidal test found that the survival rate of Pseudomonas aeruginosa treated with 0.36 mg/L of ozone for 10 min was less than 1.0%, and that of Streptococcus faecium reacted with 0.31 mg/L of ozone for 10 min was less than 0.1%. When the ozone was more than 0.45 mg/L and the time was 10 min, the survival rates of Escherichia coli was under 2.0%. The results of the flow germicidal test showed that the probability of survivability of Escherichia coli, Pseudomonas aeruginosa and Streptococcus faecium treated with 0.20-0.60 mg/L of ozone for 3 min were under 0.01%, with the killing rates of more than 99.99%.
