摘要
正渗透具有低能耗、低污染、高回收等特点,其应用范围非常广泛。具有高渗透压的驱动液是正渗透技术的核心问题。正渗透驱动液的类型有直接利用型和循环利用型,后者包括NH3/CO2汲取液、磁性驱动液、有机化合物驱动液和无机化合物驱动液。随着正渗透驱动技术的发展,驱动液已从简单的盐类、糖类转变为功能性物质。正渗透技术发展空间巨大,将成为解决困扰人类可持续发展的水资源和能源问题的关键技术之一。
The forward osmosis （FO） has good properties of low energy-consuming, low pollution and high recovery with very wide fields of application. The draw solution with high osmotic pressure is the key to the FO technology. The FO draw solution includes direct-use type and recycling type, whose latter one includes NH3/CO2, magnetic, organic compound and inorganic compound draw solutions. With the development of FO technology, the draw solution has changed fxom simple salt, sugar into functional materials. FO technology has great development space, which will be one of key technologies for solving the problems of water and energy resources troubling the human sustainable development.
