Abstract

Flow-electrode capacitive deionization (FCDI) is an innovative approach for removing charged ions from untreated water, utilizing the interaction between ions and flow carbon electrodes. A review of recent publications on FCDI reveals a predominant focus on salt removal from water (desalination) and electro-sorption processes. Though desalination is just one step in improving the water quality, it is worthwhile looking at the research in the context of FCDI techniques that involve other water treatment methods. This paper offers a detailed review of recent literature on FCDI applications in wastewater treatment. Given the broad scope of wastewater treatment, the specific areas where FCDI shows promise, including removal of heavy metal and radioactive elements, organic micropollutant elimination, halogen removal, and resource recovery, are addressed. Additionally, we assess the current research landscape and propose potential future directions in this evolving field.

探讨流动电极电容去离子在生活和工业废水处理中的潜力。

流动电极电容去离子（FCDI）是一种利用离子与流动碳电极之间的相互作用，从未经处理的水中去除带电离子的创新方法。对最近关于FCDI的出版物的审查表明，主要侧重于从水中除盐（脱盐）和电吸附过程。虽然海水淡化只是改善水质的一个步骤，但在涉及其他水处理方法的FCDI技术背景下进行研究是值得的。本文对近年来有关FCDI在废水处理中的应用进行了综述。考虑到废水处理的广泛范围，FCDI在去除重金属和放射性元素、消除有机微污染物、去除卤素和资源回收等特定领域显示出前景。此外，我们评估了当前的研究前景，并提出了这一不断发展的领域的潜在未来方向。
