摘　　要：随着水中氟元素的增多,饮用水氟含量严重超标,氟危害已经影响到人们正常生活。文章介绍了当前氟在水处理中的几种方法,有吸附法、化学沉淀法、混凝沉淀法、电凝聚法、离子交换法和反渗透法,同时介绍了纳米材料作为吸附剂的高效新型方法。通过几种方法的描述,指出水中离子的种类、含量、氟初始浓度等影响因子对除氟过程有很大影响,提出降低环境离子的影响和深入研究去除机理来提高除氟效果。With the increase of fluoride in water, the fluoride content in drinking water exceeds the standard, and the harm of fluoride has affected people＇s normal life. This paper introduces the current methods of fluorine in water treatment, adsorption method, chemical precipitation process, coagulation precipitation, ion-exchange resin method, reverse osmosis,at the same time introduced the nanomaterials as adsorbent efficient new method. Through the description of the methods, the type, content of ions in water, initial concentration of fluorine and other influence factor has a great influence on the fluoride in process, put forward to reduce environmental ion and further study of the influence of removing mechanism to improve the effect of fluoride.
