| 膜分离法 Membrane separation 膜分离技术是利用膜对混合物中各组分选择透过性能的差异来分离、提纯和浓缩目标物质的新型分离技术。 Membrane separation technology is a new separation technology to separate, purify and concentrate target substances by using the difference of selective permeability of each component in the mixture. 目前常用的膜技术有超滤、微滤、电渗析及反渗透。其中的超滤、微滤用于工业废水的处理时，不能有效去除污水中的盐分，但可以有效截留悬浮固体(SS)及胶体COD；电渗析(electrodialysis)和反相渗透(RO)技术是最有效和最常用的脱盐技术。扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训 At present, the commonly used membrane technologies are ultrafiltration, microfiltration, electrodialysis and reverse osmosis. When ultrafiltration and microfiltration are used in the treatment of industrial wastewater, they can not effectively remove the salt in the wastewater, but can effectively intercept the suspended solids (SS) and colloidal cod; Electrodialysis and reverse osmosis are the most effective and commonly used desalination technologies. 限制膜技术工程应用推广的主要难点是膜的造价高、寿命短、易受污染和结垢堵塞等。伴随着膜生产技术的发展，膜技术将在废水处理领域得到越来越多的应用。 The main difficulties of limiting the application and popularization of membrane technology are high cost, short service life, easy to be polluted and clogged. With the development of membrane production technology, membrane technology will be more and more applied in the field of wastewater treatment. |
