Abstract: Xiaoqin island seawater desalination project is a part of the freshwater supply system of the whole island. Its freshwater production capacity is 100 m³/d,and the produced freshwater is mainly used as drinking water for the inhabitants on the island. The project background,water intake scheme,treatment process,debugging and trial operation,cost,etc. are introduced in this paper,and the existing problems and social benefits of the project analyzed. Reverse osmosis desalination technology has the advantages of low energy consumption and low cost. Compared with other freshwater supply methods,it is more suitable for remote island areas.

Key words: reverse osmosis, seawater desalination, energy recovery

摘要： 小钦岛海水淡化工程为该岛淡水供应系统的一部分，产淡水能力100 m³/d，产品水用于岛上居民的生活饮用水。从工程背景、取水方案、处理工艺、调试及试运行、成本等方面进行介绍，并对工程中存在的问题、社会效益等进行分析。反渗透海水淡化技术具有能耗低、成本低等优势，相较于其他淡水供应方式更适合边远海岛地区。
