摘要
高氟饮用水一直威胁着人类的健康,纳滤膜技术以其出水水质稳定、选择性分离和保留一定离子等优点,使其在饮用水处理中具有较好的应用前景。文章详细介绍了高氟饮用水特点、国内外相关除氟技术和纳滤选择性除氟技术的特点及其应用研究的最新进展,并给出纳滤除氟系统在应用设计中优化组合排布的建议。
Drinking water with high fluoride has been threatening human health. Nanofiltration membrane technology has good application prospect in water treatment for its advantages of good water quality and selective separation ability. The characteristics of high fluoride drinking water,relevant domestic and foreign fluoride removal technologies, as well as the characteristics of nanofiltration technology for selective defluorination in the latest study progress and its application were introduced. In addition,the membrane design and optimization arrangement for selective defluorination during its application were also suggested.
