坑道空气污染评价及改善措施

目的在坑道空气质量调查基础上,对坑道空气污染状况及危害性进行评价并提出改善措施,为战时或特殊情况下人员进驻提供科学依据。方法对坑道内空气细菌总数、真菌数、真菌毒素、厌氧菌数及部分坑道的床垫、地面、墙壁等物体表面进行真菌检测。结果坑道空气真菌污染十分普遍,有的非常严重,以半密闭型坑道真菌浓度最高为(5 950±3 522)cfu/m3,房间为(9 500±4 128)cfu/m3。坑道医院内床垫表面真菌高达116 400 cfu/cm2,地面为12 300cfu/cm2,墙壁为890 cfu/cm2。结论坑道空气污染尤其是真菌污染严重,人员进驻前必须进行坑道通风,增加进入坑道特别是进入坑道房间内的新风量,必要时进行彻底的空气消毒,减少空气真菌对坑道内固定设施、战备物资及进驻人员健康的不利影响。

Evaluation of Air Pollution in Tunnels and the Improved Measures

Objective To evaluate the air pollution and its perniciousness and point some improved measures based on air quality research of the tunnels,and to provide a basis for personnel's entrance in wartime or under some special conditions. Methods The total bacteria,fungi,fungal-toxin,and anaerobic bacteria in the air of the tunnels,and the fungi number of some objects' surface in part of tunnels,such as mattress,ground and wall were detected. Results Air fungi pollution was extremely universal in tunnels.Some tu...
