【摘要】：目的通過(guò)對(duì)空氣凈化器除菌性能檢測(cè)中液體撞擊式和固體撞擊式采樣法的分析和比較,探討合理的采樣方法。方法分別用兩種采樣方法采集30立方米負(fù)壓氣霧室的空氣中自然菌和白色葡萄球菌氣溶膠,對(duì)采樣結(jié)果進(jìn)行統(tǒng)計(jì)分析。結(jié)果兩種采樣方法對(duì)空氣自然菌的采樣結(jié)果的差異性不顯著;兩種采樣方法對(duì)人為釋放的微生物氣溶膠的采樣結(jié)果存在顯著性差異,平板采樣法的敏感度較高,其中在初始濃度的氣溶膠采集中,兩組結(jié)果具有顯著的相關(guān)性,線性回歸關(guān)系極顯著。結(jié)論人工微生物氣溶膠的環(huán)境穩(wěn)定性差,在液體采樣過(guò)程中消亡率高;在空氣凈化器除菌性能檢測(cè)中,可用液體撞擊式采樣法采集氣霧室0 h微生物氣溶膠。
[Abstract]:Objective to analyze and compare the liquid impingement sampling and solid impingement sampling in the performance test of air purifier. Two sampling methods were used to collect natural bacteria and Staphylococcus albus aerosols from 30 cubic meters of negative pressure aerosol chamber. Results there was no significant difference between the two sampling methods for the natural bacteria in the air, and there was significant difference between the two sampling methods for the artificially released microbial aerosol. The sensitivity of the plate sampling method is high, among which the results of the two groups have significant correlation and linear regression relationship in the initial concentration of aerosol collection. Conclusion the environmental stability of artificial microbial aerosol is poor. In the process of liquid sampling, the microbial aerosol can be collected by liquid impingement sampling method for 0 h.
