摘要
按照高分子类吸附剂、天然矿物类吸附剂、稀土金属类吸附剂等吸附媒介,叙述了近年来国内外含氟废水吸附处理的研究现状,介绍了这些吸附剂特性。对含氟污水吸附处理技术今后的研究方向提出了建议,认为目前氟吸附剂距离实用化还有很大差距,应提高吸附剂利用率和处理效率,克服干扰因素的影响;延长吸附剂的使用寿命,提高吸附剂再生能力,解决后续处理困难问题;深入研究吸附剂的毒性作用及吸附机理,开发新的吸附剂。
According to several adsorption media such as polymer, natural mineral and rare-earth metal, overseas and domestic research status of fluoride wastewater adsorption treatment was reviewed here. Research direction of fluoride wastewater adsorption treatment technology was proposed. Because of the large gaps of fluoride absorbent practical, we should improve the availability and treatment efficiency of absorbent, and overcome the interference factors. In addition, we should enhance the service life and regeneration capacity of absorbent to solve the post-processing difficulty. Furthermore, we study the toxic effect and adsorption mechanism of absorbent for development of new adsorbent.
