全世界饮用水的可获取量大大超过需求量和使用量,但水资源分布不均。有些地区的水奇缺,有些地方的居民则早已受到水供应不足的困扰。海水成了实际上取之不尽的水供应来源。如果淡化海水,就能有助于缓解任何临海地区日益增多的供水问题。像所有工业过程一样,海水淡化也需要能源。 The availability of drinking water throughout the world far outstrips demand and usage, but water resources are unevenly distributed. In some areas, water is scarce and residents in some places are already suffering from inadequate water supply. Sea water has become a virtually inexhaustible source of water supply. If we desalinate, we can help to alleviate the ever-increasing problem of water supply in any coastal area. Desalination, like all industrial processes, also requires energy.
