【摘要】：目的觀察二氧化氯(ClO2)對坑道空氣進(jìn)行消毒的效果,同時(shí)測定空氣中ClO2濃度及降解時(shí)間,為部隊(duì)進(jìn)入消毒后房間提供安全依據(jù)。方法用撞擊法及沉降法同時(shí)檢測坑道空氣消毒前后細(xì)菌總數(shù)及真菌數(shù),用ClO2空氣監(jiān)測儀(iTX)監(jiān)測坑道內(nèi)、外3種類型房間空氣中ClO2濃度,觀察降解時(shí)間。結(jié)果(1)坑道房間空氣用0.1%C1O2劑量為10 mL.m-3消毒30 min,撞擊法及沉降法檢測細(xì)菌總數(shù)分別減少94.6%、93.5%,真菌數(shù)分別減少92.1%、89.6%。(2)坑道房間、坑道外平房及密閉房間空氣中的ClO2從10 mg.m-3降解至0.3 mg.m-3安全劑量,降解時(shí)間分別為961、45及639 min。結(jié)論(1)房間密閉性能好,墻面使用不易吸水的材料,ClO2降解速度慢,否則降解較快。(2)以0.1%ClO2劑量為10 mL.m-3用于坑道空氣消毒,殺菌效果滿意。消毒后96 min,ClO2濃度符合衛(wèi)生標(biāo)準(zhǔn),部隊(duì)及防空人群可以進(jìn)入,120 min降解完全,進(jìn)入時(shí)更安全。
[Abstract]:Objective to observe the efficacy of chlorine dioxide (CLO _ 2) in disinfection of tunnel air, and to determine the concentration and degradation time of ClO _ 2 in the air so as to provide a safe basis for the troops to enter the room after disinfection. Methods the total number of bacteria and fungi before and after disinfection were detected by impact method and sedimentation method. The concentration of ClO2 in the air of three types of rooms outside and inside the tunnel was monitored by ClO2 air monitor (iTX), and the degradation time was observed. Results 1) the air in the tunnel room was disinfected with 0.1 mL 路m ~ (-3) for 30 min, the total number of bacteria detected by impingement method and sedimentation method decreased 94.66 ~ (93. 5), and the number of fungi decreased 92. 1% and 89. 6% 路2% respectively) in the tunnel room, the total number of bacteria was decreased by 94. 6% and 93. 5%, respectively. The degradation time of ClO2 from 10 mg.m-3 to 0.3 mg.m-3 was 961c45 and 639mins respectively. Conclusion (1) the room is well sealed, and the degradation rate of ClO2 is slow when the wall is not easy to absorb water. Otherwise, the degradation rate is faster. 2) the 0.1 ClO2 dose of 10ml 路m-3 is used to disinfect the air in the tunnel, and the bactericidal effect is satisfactory. The concentration of CLO _ 2 at 96 min after disinfection was up to the hygienic standard, and the troops and air defense people could enter and decompose completely for 120 min, and it was safer to enter.
