臭氧与紫外线协同灭活脊髓灰质炎病毒效果的研究

STUDY ON SYNERGETIC EFFICACY OF OZONE AND ULTRAVIOLET RAYS IN INACTIVATING POLIOVIRUS

为了解臭氧与紫外线协同灭活病毒的效果,采用悬液定量灭活试验进行了实验室观察。结果,以3.0 mg/L臭氧单独作用7 m in,可有效灭活悬液内脊髓灰质炎病毒;以辐射强度85μW/cm2的紫外线,单独作用5 m in,亦可有效灭活脊髓灰质炎病毒。以3.0 mg/L臭氧与紫外线联合作用,仅需要1 m in即可有效灭活悬液内脊髓灰质炎病毒。结论,臭氧与紫外线联合应用,对灭活悬液内脊髓灰质炎病毒具有明显的协同增效作用。

In order to know the synergetic efficacy of ozone and ultraviolet rays in inactivating virus, suspension quantitative inactivating test was used to carry out laboratory observation. Results： Ozone 3.0 mg/L alone with a 7 rain contact time could effectively inactivate poliovirus in suspension. Ultraviolet rays at radiation intensity 85 μW/cm^2 alone with a 5 rain radiation time also could effectively inactivate poliovirus. When ozone 3.0 mg/L was combined with ultraviolet rays, only 1 rain was required to effectively inactivate poliovirus in suspension. Conclusion： Combination of ozone and ultraviolet rays has significant synergetic efficacy in inactivating poliovirus in suspension.
