摘要
海水淡化是解决淡水危机的重要途径,新工艺、新型膜材料及新能源的利用,有望进一步降低海水淡化成本。介绍了多效蒸发、多级闪蒸、压气蒸馏、反渗透等海水淡化工艺以及基于膜技术的海水淡化集成工艺的最新进展,分析了利用风能、太阳能、核能和化学热能等可替代能源进行海水淡化的可能性,在此基础上,提出了海水淡化未来的发展方向。
Seawater desalination is an important way to solve the problem of fresh water shortage. Lower cost can be obtained by utilizing new technology and membrane materials and alter native energy sources. Recent improvements in seawater desalination using multi-stage distillation, multi - stage flash distillation, vapour compression distillation, reverse osmosis and hybrid processes based on membrane technology are reviewed. The possibility of using wind energy, solar energy, nuclear energy and chemical thermal energy is also discussed, finally the trends towards the future of seawater desalination are provided.
