摘要
当国民经济高速发展,随之而来的是环境污染,同时也加剧了地区性的缺水危机。文中评价了水资源开发利用的现状,分析了水资源未来演变趋势,探寻解决水资源供需要求的发展方向。随着技术条件进一步改善,多效蒸馏、多级闪蒸和反渗透法是海水淡化的主要方法,预计海水淡化的产水成本将逐渐下降,海水淡化将成为解决淡水资源短缺的重要措施之一。
Regional water crissis and environmental contamination take place along with high development of China＇s economy. The status of water source utilization and its future trend have been evaluated so as to seek a solution of water supply and needs. Main desalination ways such as MED, MSF and reverse osmosis have been described in the article. It will surely be one of important measures to solve the shortage of freshwater with sea water desalination along with gradual decreasing of water producing cost.
