十种家庭饮水除氟器的功能与应用

本文报告十种家庭饮水除氟器的功能与应用的调查结果。在实验室比较了五种活性氧化铝除氟器的功能,然后到津、内蒙和鲁的16个村调查了199户氧化铝(3种类型)和110户骨炭除氟器(4种类型)的应用情况。处理水含氟量<1.0mg/L的合标率分别为48.2％和50.9％。家庭除氟器的功能应予肯定。主管部门的重视,用户自觉参与,除氟器的合理设计和便于使用,以及良好的滤料再生,是影响处理水合标率的关键。目前,有些地方的使用率很低(最低约10％左右),亟待解决。

Investigation on the Function and Operational Performance of 10 Types of Household Drinking Water Defluoridation Device

This article reported the results of investigation on the function and operational performance of 10 types of household drinking water defluoridation device. The authors compared the function of 5 types of household defluoridation device in the laboratary, then investigated 199 activated alumina defluoridation devices (including 4 types) and 110 bone char defluoridation devices (including 4 types ) in 16 villages of Tianjin Municipality, Inner Mongolia Autonomous Region and Shandong Province. The qualification rates of fluoride level < 1.0 mg/ L in treated water were 48.2 and 50.9% respectively. The function of household defluoridation device should be affirmed. Pay great attention to it by the administrative organizations, users conscious joining, rational designing of the device and easy to operation, and careful regeneration of the media were the main factors that affected the qualification rate of treated water. Recently, the problem of very low utilization rate of such device had occurred in many localities (at a lowest rate of 10% or so) must be solved quickly.
