【摘要】：[目的]了解上海市轨道交通地下车站集中式空调风管内表面微生物和积尘量污染状况,以及清洗前后的效果改善情况,为疾病预防、卫生监督等工作的开展提供科学依据。[方法]选取上海市轨道交通具有代表性的地下车站,依据DB 31/405—2012《公共场所空调通风系统运行卫生要求》进行细菌总数、真菌总数和积尘量的检测。[结果]共选择代表性车站30个,风管内表面的细菌总数由清洗前的14.33 cfu/cm2减少到清洗后的1.49 cfu/cm2,真菌总数由清洗前的3.51 cfu/cm2减少到清洗后的1.25 cfu/cm2,积尘量由清洗前的10.08 g/m2减少到清洗后的0.45 g/m2,此3项指标在清洗前后差异均有统计学意义(P0.01)。[结论]清洗是改善轨道交通地下车站集中式空调通风系统风管内表面污染状况的有效措施。
[Abstract]:[Objective] to understand the pollution status of microbe and dust in the inner surface of the centralized air conditioning air duct in Shanghai metro station, and the improvement of the effect before and after cleaning, and provide scientific basis for the development of disease prevention and health supervision. [Methods] select the representative underground station of Shanghai rail transit system, according to DB 31/405 The total number of bacteria, the total number of fungi and the amount of dust accumulated in the air conditioning and ventilation system in 2012< public places. [results] 30 representative stations were selected. The total number of bacteria on the inner surface of the wind pipe was reduced from 14.33 cfu/cm2 before cleaning to 1.49 cfu/cm2 after cleaning, and the total number of fungi was reduced from 3.51 cfu/cm2 before cleaning to after cleaning. The dust volume of 1.25 cfu/cm2 was reduced from 10.08 g/m2 before cleaning to 0.45 g/m2 after cleaning, and the difference between the 3 indexes before and after cleaning was statistically significant (P0.01). [Conclusion] cleaning is an effective measure to improve the internal surface pollution of the centralized air conditioning and ventilation system in rail transit stations.
