摘要
金属冶炼、铝电解及电池生产等化工领域排放大量的含氟废水,实现含氟废水的深度处理(<1 mg/L),对保障人体的健康安全具有重要意义。阐述了现有吸附剂的分类、除氟机理及优缺点,总结了适合深度除氟的吸附剂及其改性方式,为含氟废水深度处理技术研究提供参考。
A large amount of fluorinated wastewater is discharged from chemical fields such as metal smelting,aluminum electrolysis and battery production,the realization of deep treatment of the fluorinated wastewater(<1 mg/L)is of great importance to guarantee the health and safety of human beings.The classification,fluoride removal principles,advantages and disadvantages of existing adsorbents are described,and the types of adsorbents suitable for deep fluoride removal and their modification methods are summarized to provide a reference for the research of fluoride-containing wastewater deep treatment technology.
