摘要
氟是地球表面分布最广的元素之一,长期摄入过量氟会引起氟中毒(地方病)。利用天然矿物中的某些特殊性能,经提纯、活化、改性加工研制出除氟颗粒滤料和活化再生剂;探讨高氟地下水形成机理;阐述滤料除氟原理和影响除氟因素;设计操作简便除氟装置;制定行之有效的除氟工艺流程,在2个农村水厂进行除氟工程扩大应用试验,运行2年来取得较好的除氟效果。
Fluorin is one of the elements that is most widely distributed on the earth surface and a excessive in-take of fluorin may cause fluorin toxicosis （endemic）. An endemic of fluorin toxicosis may hurt the health of the natives and affect the development of local economy. The use of some characteristics hosted in the natural minerals may manufacture fluorin eliminating grain filter material and activated regenerator through purification, activation and modification. The formation mechanism of high fluorin in the groundwater is discussed. The fluorin eliminating principles of the filtering materials and the factors that affect the elimination of fluorin are stated. The fluorin eliminating apparatus is designed for easy operation. The effective folwsheet is framed. An enlarged trial application was carried out in the two rural groundwater plants and favorable effect was obtained through a two-year practice.
