摘要
对采用不同的金属氧化物或金属水合氧化物作为吸附剂,不同的硅酸盐类矿物作为载体的改性滤料去除饮用水中过量氟的性能进行了评述。论述了这些吸附剂和载体各自的优缺点和应用现状以及改性滤料在饮用水除氟方面的优越性。并初步探讨了不同的改性滤料的除氟机理和去除效果、可能的影响因素和我国现今除氟技术的应用概况。说明在除氟领域中,改性滤料作为一种无毒害,且经济上可行,操作上可行的除氟材料其发展空间还很大。
It reviews and evaluates the existing applications of different metallic oxides and hydrated matter as adsorbents, silicate mineral as carrier to the removal of fluoride from drinking water, talking about their respective merits and defects. It also discusses the mechanism and effect of fluoride removal with modified filter media, and general situation of its usage in fluoride removal techniques. So, modified filter media, as a kind of antipoisonous and economically feasible matter, will embrace a good foreground in the removal of fluoride.
