| 摘要: |
| 采用微生物检测技术与致病菌检测技术对教室内环境卫生状况进行检测.分别检测教学环境和教学设施中细菌菌落总数、大肠菌群和致病菌3项微生物指标.利用平板法检测空气中存在的细菌菌落;利用棉拭采样法对教具、设施等进行大肠菌群和致病菌的检验.根据检测结果,了解环境动态变化趋势和教室环境污染状况,针对不同的微生物群制定合理的消毒方法和程序.经检测,9、10月份教室空气质量较好,平均菌落总数不超过10.教学设施在使用后检测到的平均菌落总数要大于使用前的数量,9月检测到的平均菌落总数要大于10月检测到的数据.其中课桌检测到的平均菌落总数范围值在80~120之间,手把检测到的平均菌落总数范围值在10~50之间.教学用具检测到的平均菌落总数范围值在40~80之间.同时,大肠菌群和沙门氏菌的检测结果呈阴性. |

| Abstract: |
| Adopt a microorganism and pathogenic bacteria examination technique to carry on an examination towards the environment and sanitation condition of the classroom.Examine the bacterial colony,coliform group and pathogenic bacteria,these three microorganism index signs in teaching environment and facilities.Use flat band method to examine the sanitation in the air;use cotton swab sampling method to examine the coli group and pathogenic bacteria.According to the results of examination,find out the variety trend of the dynamic state of environment and pollution of the environment condition,establish the reasonable disinfection method and procedure aimed at different microoganismses.Through testing,we confirm that the air quality is good in September and October.The average of total numbers of colony is less than 10.The average of total numbers of colony of the used teaching facilities is greater than the number of before use.The average of total numbers of colony detected in September is greater than detected in October.The range of total numbers of colony detected in desks is from 80 to 120.The range of total numbers of colony detected in handlebars is from 10 to 50.The range of total numbers of colony detected in teaching tools is from 40 to 80.The detection results of coli group and salmonella is negative. |
