海水淡化技术,顾名思义常被理解为只能淡化海水,没有别的用途。实际上,它属于分离科学与技术,即用化学的、物理的方法从溶液中取出水,或除去溶液里的盐,二者都能达到淡化的目的。国外把利用海水、苦咸水生产出适合人们日常用的淡水,叫做除盐;把淡水进一步纯化生产出特殊工业(如电子、发电和医药等)所需的纯水、超纯水,叫做除矿。此 Desalination technology, as its name implies, is often understood as desalinating seawater for no other purpose. In fact, it is a separation science and technology that uses chemical and physical methods to remove water from a solution or to remove salt from a solution, both of which can achieve the purpose of desalination. Foreign use of sea water, brackish water to produce suitable for daily use of fresh water, called desalination; the further purification of fresh water to produce special industries (such as electronics, power generation and medicine, etc.) required for pure water, ultra-pure water called mine. this
