摘要: 纳滤膜在水处理中应用:NF膜的独特性能决定了其特有的广阔应用范围,可主要归纳为以下几个方面。 软化水处理 由于能有效的截留二价离子,具有较低的操作压力和较大的水通量,对苦咸水进行软化和脱盐成为纳滤应用的*大市场。其主要优点是无污泥,无需再生,完全去除悬浮物和有机物,操作简单,占地少等。而在投资、操作和价格等方面与常规方法相近,因此在这个领域具有较强竞争力。 饮用水净化 随着水污染加剧,使人们对饮用水水质越来越关心。试验表明,NF膜可以去除**过程产生的微毒副产物,痕量的除草剂,杀虫剂,...

如果控制适当条件,NF膜还可以将溶液中的不同金属实现分离,如Cd和Ni的分离,先将他们转化成CdCl2和NiCl2,加入NaCl,分别形成荷电络合物和非荷电络合物。NaCl浓度为015mol/L时,在溶液中镉的主要存在形式是CdCl2,但是镍并不以络合形式存在,而以镍离子方式存在,用带正电的NF膜处理,截留镍离子,而让镉自由通过,即可实现金属间的分离。
