PM2.5处理器室内样机研发成功

  记者日前从在上海市举行的PM2.5污染与防治战略研讨会上获悉,PM2.5处理器有望进入家庭。

  上海市大气颗粒物污染与防治重点实验室主任陈建民在会上披露,该实验室已研制出PM2.5处理器样机。其工作原理是将颗粒物雾化,增加颗粒物重量后使其沉降,以此减少空气中颗粒物的含量。据介绍,已经完成的样机体型庞大,是个高约3米、直径1.5米的圆筒状机器,每个小时能处理约100立方米室内空气,PM2.5去除率达到90%。室内和室外PM2.5的含量差别很大,在重度污染时,室内的PM2.5含量比室外低50%左右,在非重度污染时,这一数字还会上升到70%左右。这一处理器小型化后有望进入家庭。

  另据悉,复旦大学公共卫生学院科研团队正在构建“空气质量(雾霾)健康指数”。复旦大学公共卫生学院阚海东教授表示,世界卫生组织最新评估结果表明,大气PM2.5是我国排名第四位的健康危险因素,2010年,我国约有120万名居民的死亡与PM2.5污染相关。

  目前,上海科学家正在研制一种PM2.5处理器,样机已完成,室内PM2.5去除率可达90%,小型化后有望进入家庭。

  上海市大气颗粒物污染与防治重点实验室主任陈建民向记者透露,由该实验室研制的PM2.5处理器的大致工作原理是将颗粒物雾化,增加颗粒物重量后使其沉降,以此减少空气中颗粒物的含量。

  已经完成的样机体型庞大,是个高约3米、直径1.5米的圆筒状机器,每小时能处理约100立方米室内空气,PM2.5去除率达到90%。

  当然室内和室外PM2.5的含量差别很大,在重度污染时,室内的PM2.5含量比室外低50%左右,在非重度污染时,这一数字还会上升到70%左右。
