【摘要】：[目的]了解人员入驻坑道后空气微生物污染状况,采取有效消毒措施,保障入驻人员健康。[方法]①人员入驻坑道d1～5每日观察坑道空气细菌总数及真菌数。入驻d5人员离开房间,用二氧化氯(ClO2)进行空气消毒,观察消毒效果。ClO2完全降解后人员返回房间,停留24h后调查在消毒后房间有无刺激症状及不良反应。②分别对5条坑道及1个人防工事,用同样方法进行ClO2空气消毒,待降解完全后人员进入消毒后房间,停留2～3h后观察有无刺激症状及不良反应。[结果]①人员入驻坑道后,空气细菌总数及真菌数逐日增高,空气微生物污染加重。②ClO2空气消毒细菌总数及真菌数消亡率,撞击法为93.78%及92.61%,沉降法为94.38%及91.88%。③ClO2降解完全后,停留不同时间,经调查除少部分人有极轻微异味感觉外,其他均无刺激症状及不良反应。[结论]人员入驻坑道后空气微生物污染明显增加,ClO2适合坑道空气消毒,消毒效果满意,对健康无不良影响。
[Abstract]:Objective: to understand the microorganism pollution in the air after entering the tunnel, and to take effective disinfection measures to ensure the health of the personnel.[methods] 1 the total number of bacteria and fungi in the air of the tunnel were observed daily.After entering the room for 5 days, the air was disinfected with chlorine dioxide (ClO2). The disinfection effect was observed. After the degradation of ClO2, the personnel returned to the room.After 24 hours of stay, we investigated whether there were irritation symptoms and adverse reactions in the room after disinfection. 2. 5 tunnels and 1 personal defense were disinfected with the same method of ClO2 air disinfection.The irritation symptoms and adverse reactions were observed 3 hours after staying for 2 minutes.[results] 1 after entering the tunnel, the total number of air bacteria and the number of fungi increased day by day, and the air microbial pollution increased. The total number of air disinfection bacteria and the death rate of fungi were increased.The impact method was 93.78% and 92.61%, the sedimentation method was 94.38% and 91.88%.3ClO2 was completely degraded and stayed for different time. Except for a few people with very slight odorous sensation, there were no irritation symptoms or adverse reactions.[conclusion] the microorganism pollution in the air increased obviously after the personnel entered the tunnel, and ClO2 was suitable for air disinfection in the tunnel. The disinfection effect was satisfactory and had no adverse effect on health.
