解决沿海城市水资源短缺的方法:海水淡化

Seawater Desalination:a Way to Solve the Water Shortage in Coastal Cities

水资源是维系城市发展必不可少的一个因素。如何解决沿海城市用水紧张的问题是长期以来萦绕在城市管理者脑中的一个棘手问题。相对于内陆缺水地区,沿海城市由于过度损耗地下水造成的地面沉降或海水入侵是造成沿海城市用水紧张的主要原因之一。文章中主要针对沿海城市用水紧张的问题,根据国内外最新研究进展,分条目的列举出了几种常规的以及新型且有发展前景的海水淡化技术。此外,针对这些我们还进一步对每一种海水淡化技术的优势以及发展前景进行了相关的讨论。笔者希望此文对沿海城市解决水资源短缺的问题会有一定的借鉴意义。

Water resources played an important role in maintaining the development of the cities. How to solve the problem of water shortage plagued the city manager for a long time. Compared with the inland areas, the coastal areas suffered the water shortage problem from the over-exploitation of ground-water. As a result, the seawater invaded into the freshwater area and caused the water shortage problem. In this paper we listed some common and new as well as promising seawater desalination method. Besides, we also discussed the advantage and development prospect of each technology. The authors hope that this article will help in critically analyzing the requirements and accordingly decide on the appropriate strategy to solve the problem of water shortage in coastal cities.
