Abstract:
OBJECTIVE To observe the sterilization effect of nanometer photocatalysis air sterilizer mounted in hospital.METHODS We carried out a dynamic survey on air average numbers of colony through field experiment and practical operation.RESULTS The field experiment displayed that the air bacterium dissolution rate was 55.64-75.94% and the bacterium content degraded as time extended,after nanometer photocatalysis air sterilizer been used 1-2 h;the result of practical operation in four seasons of the year revealed that the average bacterium colony numbers in each ward region was lower than before sterilizer mounted,the air bacterium dissolution rate was 73-82.3% in the third ward region and 44.5-76.3% in the fourth ward region.CONCLUSIONS It is effective to use the nanometer photocatalysis air sterilizer to sterilize the air in hospital under the condition of inspection.The airflow of the central air conditioning can practice the air sterilization function more validly.
