摘要
目的了解高校食堂就餐区紫外线消毒装置使用现状及其消毒效果。方法通过现场调查和平板沉降采样检测,对天津市7所高校27个食堂就餐区紫外线消毒装置使用状况进行调查。结果本次调查的27个高校食堂就餐区中,有16个食堂就餐区安装了紫外线消毒装置,占59.26%,平均安装高度在2.58 m,间距6.5~22 m。安装有紫外线消毒装置的食堂就餐区空气中检测到细菌总数波动在105~2 358 cfu/m^3。结论天津市高校食堂就餐区紫外线消毒装置拥有率接近60%,存在使用不合理现象,食堂就餐区空气卫生质量有待进一步改善。
Objective To investigate the usage situation of ultraviolet disinfection devices installed on canteen area of university. Methods Field investigation and the gravity plate method were used to survey the usage situation of ultraviolet disinfection devices of 27 dining areas of 7 universities in Tianjin.
