摘　　要：海水淡化是解决海岛供水的重要途径,海水预处理是海水淡化技术的关键环节,完善的预处理方案可以保证反渗透海水淡化系统的正常运行,延长反渗透膜的使用寿命,降低海水淡化成本。本文针对小型海水淡化系统的预处理技术的应用,比较分析不同取水方式条件下的预处理方案,并结合福建东门屿独立新能源海水淡化项目的具体应用,对海岛小型海水淡化系统预处理技术的应用展开研究,在试运行过程中积累了一定的经验,可为类似工程提供借鉴和指导。Sea water desalination is an important way to solve islands＇ water supply. Pretreatment of seawa- ter is the key part of desalinization, which can guarantee the normal operation of reverse osmosis （RO） de- salination and extend the life of RO membranes and reduce the cost of sea water desalin^ttion. In this pa- per, a study is conducted on pretreatment of small-sized RO sea water desalinization on the islands by making a comparative analysis of pretreatment under different sea water intake, and using the research re- suits in new energy independent power-grid desalination system in Dongmen islet. In the field trial opera- tion, some good experiences have been gained, which can provide a reference and guidance for similar projects.
