新型饮用水除氟吸附剂研究进展

Progress in Research on Novel Fluoride Adsorbent for Potable Water Treatment

吸附法是目前饮用水除氟应用最广泛的方法,而吸附剂的特性是决定除氟成本和效果的重要因素。将工农业废弃物、天然矿物及生物制剂作为除氟吸附剂,可简化吸附剂加工环节,减少环境污染,降低除氟成本。基于对国内外新型除氟吸附剂研究现状的介绍,提出新型饮用水除氟吸附剂的后续研究应侧重预处理和使用后的处置方法,以及工业化应用理论基础研究,以寻求经济、高效的治理工艺,早日大规模应用于饮用水水处理中。

Adsorption is the most widely used method for fluoride removal for present potable water. The cost and efficiency of fluoride removal are mainly influenced by the characteristics of the adsorbent. If the industrial, agricultural wastes and natural minerals and bioadsorbents are used as the adsorbent of fluoride, which can summarize the proceeding technique of fluoride adsorbent, reduce pollution to environment and decrease the cost of water treatment. The research of novel adsorbent for aqueous fluoride removal was introduced, thereafter, the trends and future use of these materials for fluoride removal were predicted. The method of pre-treatment and disposal, as well as the application in potable water treatment should be further investigated.
