反渗透-离子交换联合除盐系统的选择

INQUIRY INTO SELECTION OF COMBINED DESALINATION SYSTEM WITH REVERSE OSMOSIS-ION EXCHANGE

通过在工程设计实践中,对受海水倒灌水源反渗透系统段间增压泵的研究,提出的设置其意义可减少在水源不受咸潮影响时的第一段膜组件的进口压力及能耗;其也可用于已有的苦咸水淡化系统的工艺改造,从而提高第二段膜堆的产水量(约25%)或降低系统的能量消耗;此外,对后续除咸系统的选择,提出了可供选择的方案。

Through the practice of engineering design, for the study of boosters between the sections of RO system which was affected by seawatr inrasion, the inlet pressure and energy consumption at the first section's membrane module can be decreased when the water source was not affected by salty tide. The system can also be used for the technological reformation with brackish water desalination system, thus the water output of the. Second section's membrane stack can be raised by about 25%, or the system's energy consumption can be lowered. In addition, a scheme was put forward for the selection of following desalination system.
