摘　　要：综述了近年来国内外饮用水除氟技术的研究新进展,介绍了沉淀、吸附和膜分离三种处理工艺的热点研究——电凝法、载镧改性吸附法和唐南透析法的基本原理和发展动态,并分析了各自的优缺点。认为开发高效、低成本、易操作和安全的饮用水新型除氟技术是目前的研究重点和方向。New progress of sdudies on defluoridatlon technology home and abroad is summarized in this paper. Especially the fundamental and development of three technologies-electrocoagulation, lanthanum-modified absorbent and donnan dialysis are introduced as the key process of precipitation, adsorption and membrane separation, respectively. Their advantages and limitations are analyzed. It is suggested that the future defluoridation technology should follow the principles of high efficiency, low cost, easy operation and high safety.
