基于资源综合利用的海水淡化工艺选择

介绍了海水淡化技术现状及浓海水综合利用的意义，分析了低温多效蒸馏和反渗透两种海水淡化工艺在浓海水综合利用时的不同之处，并以1．56万t／d海水淡化工程为例对两种海水淡化工艺进行了综合比较。基于资源综合利用的海水淡化工艺比较为海水淡化工艺的选择提供了一种新的思路，为沿海电厂海水淡化工程在两种海水淡化工艺选择时提供一定的借鉴。

Seawater technologies selection based on integrated utilization of resources

Power plant integrated with seawater desalination process is an effective solution for resolving the shortage of freshwater in coastal areas of China. The brine from desalination plant can potentially affect marine life and ecology. Brine reusing not only can to reduce marine pollution, but also can obtain the chemical resources to compensate for lack of land resources,and dilute the cost of desalination. So Power plant integrated with seawater desalination process is a strategy for combating water shortage. The technical comparison of SWRO and LT - MED based on the capacity of 15 600 t/d seawater desalination project which integrated with brine reusing is presented,and a new approach for selection of the two desalination processes is provided.
