反电渗析法海水淡化副产浓水盐差能利用

摘要海水淡化是解决淡水资源短缺的有效途径，其副产的浓海水具有较高的浓度，而基于离子交换膜的反电渗析（RED）法发电是对盐差能利用的有效手段。通过模拟计算研究了以反渗透法海水淡化副产的浓水和海水为进料的情况下，RED装置发电的功率密度和能量效率，并探讨了多级操作对于RED系统功率密度和能量效率的影响。结果表明：单级RED的发电功率密度随水回收率的提高和隔板厚度的降低而增大，但过程的能量效率均低于30%。RED多级操作能显著提高系统的能量效率。探讨了影响淡化浓海水盐差能利用效果的因素，并提出多级RED作为提高浓水盐差能利用效率的手段，研究结果为海水淡化副产浓水的利用提供了一种新的思路。

Abstract： Seawater desalination is an effective approach to solve the problem of worldwide water scarcity. The process discharge high concentration brine as by-product together with fresh water. The reverse electrodialysis(RED) is an emerging ion-exchange-membrane-based process that draws electrical power from the salinity gradient between two solutions. RED was used to harvest the salinity gradient energy between the brines discharged from seawater reverse osmosis (SWRO) unit and the seawater. The power density and energy efficiency of both the single-and multi-stage RED process were studied by modeling. The power density of the single-stage RED increases with the increasing of water recovery in SWRO and the decreasing of RED compartment thickness, but the efficiency is less than 30%. Multi-Stage RED could further improve the energy efficiency. This research provided a new approach for brine management.
