超声波雾化消毒机消毒效果观察

为了观察超声波雾化消毒机的杀菌效果,分别用微生物监测仪器法和平板沉降法对其进行了检测。结果,在室温20～23℃,相对湿度为70%～80%条件下,在约3m3的汽车内,用微生物监测仪器法和平板自然沉降法进行了监测。消毒前,其空气自然菌数分别为530cfu/m3和4710cfu/m3;启动超声波雾化消毒机消毒15min,车内空气中自然菌数分别为3cfu/m3和0cfu/m3,消亡率分别为99.64%和100.00%。结论,超声波雾化消毒机对汽车内空气自然菌具有良好杀灭作用。

OBSERVATION ON DISINFECTION EFFICACY OF ULTRASOUND ATOMIZING DISINFECTOR

In order to observe the germicidal efficacy of the Ultrasound Atomizing Disinfector, microbial monitoring instrument method and plate sedimentation method were used for examination. Results: Under conditions of 20～23℃ room temperature and 70%～80% relative humidity, microbial monitoring instrument method and plate natural sedimentation method were used for monitoring in a car of about 3 m3 in size. Before disinfection, the natural bacterial count of air was 530 cfu/m3 and 4710 cfu/m3 respectively. After disinfection with the Ultrasound Atomizing Disinfector for 15 min, the natural bacterial count in air inside the car was 3 cfu/m3 and 0 cfu/m3 respectively, with reduction rate of 99.64% and 100.00% respectively. Conclusion: The Ultrasound Atomizing Disinfector had good efficacy in killing natural bacteria in air inside the car.
