红河州瓶(桶)装饮用水厂灌装车间空气洁净度调查

Indoor Air Clean Investigation of the Filling Workshop of Bottled Water Production Factory in Honghe

通过对红河州辖区内的瓶(桶)装饮用水灌装间进行空气洁净度检测,了解饮用水厂灌装车间的空气洁净度水平。依据《GB50073-2013洁净厂房设计规范》《GB50591-2010洁净室施工及验收规范》和《GB50687-2011食品工业洁净用房建筑技术规范》,于2015年1月—2017年12月对红河州内64间饮用水厂灌装车间的悬浮粒子、压差、换气次数等参数进行检测和评价。结果表明:千级洁净间的悬浮粒子合格率为95%,压差合格率为91%,换气次数合格率为45%;万级背景下百级洁净间的悬浮粒子合格率为90%,压差合格率为70%,换气次数合格率为50%。

The indoor air clean of the filling workshop of bottled water production factory was tested in order to access the air clean level of the production workshop.According to“Code for design of clean room GB50073-2013”,“Code for construction and acceptance of cleanroom GB50591-2010”,and“Architectural and technical code for cleanroom in food industry GB50687-2011”,the suspended particle,differential pressure,and times of aeration were tested and evaluated.The results indicated that the percent of pass of the suspended particle differential pressure,and times of aeration in class 1000 clean room were 95%,91%,and 45%,respectively.the percent of pass of the suspended particle differential pressure,and times of aeration in class 10000 clean roomwere 90%,70%,and 50%,respectively.
