摘要
流动电极电容去离子(FCDI)技术是在传统固定电极电容去离子(CDI)基础上发展衍生的新一代电容去离子技术,打破了传统CDI间歇式操作的局限,能够连续运行并有效应对高浓度盐水的脱盐要求。此外,FCDI因在能量/资源回收方面固有的优势而备受关注。随着水处理技术能量自给和资源循环进入探索新阶段,有关FCDI技术在能量/资源回收的特性研究显得尤为重要。例如,工艺运行参数的优化、装置构造的设计及电极和电解液特性等都可能影响能量回收效率。在资源回收方面,对废水中有价元素进行回收,不但可以实现资源的循环利用,缓解资源短缺,还可以降低对水环境的危害。因此,本文综述了FCDI在能量回收、能耗方面的影响因素及资源回收中的应用潜能,有助于推动FCDI技术进一步优化和广泛应用,使其在能量回收与资源循环领域发挥更大作用。
Flow electrode capacitive deionization(FCDI)is a new generation of capacitive deionization technology derived from the traditional fixed electrode capacitive deionization(CDI),which breaks the limitations of the traditional CDI's intermittent operation,enabling continuous operation and effective desalination of high-concentration brines.In addition,FCDI has garnered attention for its inherent advantages in energy/resource recovery.As the energy self-sufficiency and resource recycling of water treatment technology enters a new phase of exploration,the characterization of FCDI technology in terms of energy and resource recovery is of particular importance.For instance,the optimization of process operating parameters,the design of device structure and the characteristics of electrodes and electrolyte may affect the energy recovery efficiency.In terms of resource recovery,the recovery of valuable elements in wastewater can not only realize the recycling of resources to alleviate the shortage of resources,but also reduce the harm to the water environment.Therefore,this paper reviews the influencing factors of FCDI in energy recovery,energy consumption and the application potential in resource recovery,which can help to promote the further optimization and wide application of FCDI technology,so that it can play a greater role in the field of energy recovery and resource recycling.
