摘要
本文介绍了近年来主要海水淡化方法—— SWRO、MSF、MED的某些新进展。海水淡化市场的激烈竞争和海水淡化技术进步 ,尤其是 SWRO的进展 ,使淡化的能耗下降了近一半 ( 3k Wh m3以下 ) ,产水的出厂价也几乎下降了一半 ( 0 67美元 m3)。近两年大型海水淡化厂的国际招标中 ,SWRO以低投资费、低能耗、低产水价而占上风。预计 2 1世纪的海水淡化市场会有很大发展 ,SWRO将是主要的海水淡化方法。
The paper introduces recent some progress about the process of seawater desalination of SWRO,MSF and MED. With intensifying competition of the market of seawater desalination and the technical development, especial in SWRO, there has been significant progress in reducing the energy requirement. It was reported that total energy requirement is below 3 kWh/m 3, and the prices of desalted water fall to below $0.55/m 3 for SWRO. For large scale seawater desalting plant in international revip for proposals, SWRO won bids at lowst capitalization, power requirement and price. A great development is anticipated for the 21st century in seawater desalination market, and SWRO will be mainly process.
