某铁路车站候车室集中空调通风系统卫生状况调查

为了解铁路车站候车室集中空调通风系统卫生状况及运行特点,为相关部门加强监管、合理规划提供依据和建议,对某城际铁路10个车站的集中空调通风系统进行公共场所卫生学验收检测及日常检测,并对比两次检测结果。检测结果显示,验收检测送风卫生指标细菌总数合格率为50%、真菌总数合格率为70%;风管内表面卫生指标细菌总数合格率为40%,真菌总数合格率为40%。日常检测送风卫生指标细菌总数合格率为100%、真菌总数合格率为100%,风管内表面卫生指标细菌总数、真菌总数合格率低。提出该城际铁路车站候车室集中空调通风系统存在微生物指标超标风险,应定期检测、清洗、消毒,加强卫生管理。

Investigation on Sanitary Conditions of Centralized Air Conditioning and Ventilation System in Waiting Hall of Railway Stations

In order to understand sanitary conditions and operation characteristics of centralized air conditioning and ventilation systems in waiting hall of railway stations, and to provide basis and suggestions for relevant departments to strengthen supervision and reasonable planning, hygiene acceptance tests and daily tests of centralized air conditioning and ventilation systems in 10 stations of an inter-city railway were carried out in public places, and the comparison was made between the two test results.The test results showed that the qualified rate of the total bacteria and fungi was 50% and 70%respectively. The qualified rate of the total number of bacteria and fungi on the inner surface of the air duct were both 40%.The qualified rate of the total bacteria and fungi in daily air supply hygiene indexes is 100%, and the qualified rate of the total bacteria and fungi on the inner surface of the air duct is low. It is proposed that the centralized air conditioning and ventilation system in the waiting hall of the intercity railway station has the risk of exceeding the standard of microbiological indexes, and regular inspection, cleaning and disinfection should be carried out to strengthen health management.
