| Abstract: | In order to observe the efficacy of peracetic acid aerosol in disinfection of ward air, spray with ultralow volume sprayer and plate sedimentation sampling method were used to carry out the experimental study. The results showed that spraying 5000 mg/L water solution of peracetic acid at a dose of 20 ml/m 3 in the ward with doors and windows closed reduced more than 90% of natural bacteria in air of 10 wards after 30 min contact, with the reduction rate ranging from 93% to 100%. The results indicated that spraying of peracetic acid aerosol could fulfil the requirement of disinfection of ward air. |
