电容脱盐技术及其在废水处理中的应用

Capacitive Desalination Technology and its Application in Wastewater Treatment

废水脱盐是继COD、氮磷、重金属处理后的热点之一,而电容去离子技术是近年来迅速发展起来的一种新型的脱盐技术,其在含盐废水治理领域具有广阔前景。本文聚焦该技术的最新研究进展,对电容性脱盐的电极材料、脱盐模式、电压、极板间距等影响因素进行了综述,并对该技术的未来发展方向进行了展望。

The wastewater desalination has been deeply concerned after water pollutions of COD, nitrogen, phosphorus and heavy metals. Capacitive deionization (CDI) is a novel saline water treatment and purification technology developed rapidly in recent years, which has broad prospects in the field of saline wastewater treatment. Focusing on the current state-of-the-art of CDI technology, in this paper, the influencing factors such as electrode materials, desalting modes, voltage, plate distance and so on are reviewed. We also provide an outlook on the future development of CDI.
