反渗透与低温多效法海水淡化工艺在电站应用中的比较

摘要

The seawater desalination is the main way to obtain fresh water for a coastal power plant which was lack of freshwater resources.At present there are two main technical routes that are reverse osmosis method and low temperature multiple effect distil ation ( LT-MED) method.The comprehensive comparison of the two techniques is made.And the advantages and disadvantages are analyzed according to the regional characteris-tics and area planning of Zhoushan Islands.The most suitable seawater desalination technology for Zhoushan Power Plant is recommended.%海水淡化是淡水资源紧缺的沿海电厂向海洋获取新鲜淡水的主要方式，目前主要有反渗透膜法和低温多效热法等技术路线。对上述两种技术从工艺、技术经济性等方面进行综合比较，分析各自的优势及存在的不足。最后根据舟山地域特点及地区海水淡化规划，推荐适合舟山电厂的海水淡化技术。
