【摘要】 重金属废水对人类健康和生物多样性构成威胁，废水中重金属的去除和回收至关重要。在众多处理技术中，电沉积技术由于具有清洁、用途广泛和高稳定性等特点在去除和回收废水中金属离子方面引起广泛关注。文献检索发现，近十余年关于电沉积法金属回收的研究呈上升趋势，表明电沉积技术仍然具有较高的关注度。然而，单一电沉积工艺存在较大的局限性，为提高电沉积过程中金属回收率并降低能耗，将其与其它工艺进行耦合十分必要。本文首先分析了影响电沉积法回收金属的核心要素，包括电极材料、电化学反应器设计、操作参数和水质类型等；进一步归纳和总结了电沉积与其它电化学法、膜工艺、超声以及吸附/萃取等其它工艺耦合的研究进展；最后，对目前电沉积法回收金属所面临的问题和挑战进行了讨论，并展望了电沉积法回收金属技术的未来发展方向。更多还原

【Abstract】 Heavy metal wastewater poses a threat to human health and biodiversity. Among the treatment techniques, electrodeposition technique has attracted much attention in the removal and recovery of metal ions in wastewater because of its cleanliness, wide range of uses and high stability. It is found that the papers on metal recovery by electrodeposition at home and abroad have shown an upward trend in the past decade, indicating that electrodeposition technique is still one of the hotspots in current study and has great research potential in wastewater treatment. However, the single electrodeposition process has great limitations, so it is necessary to couple it with other processes to improve metal recovery and reduce energy consumption. In this paper, the core factors affecting metal recovery by electrodeposition were analyzed, including electrode material, electrochemical reactor design, operation parameters and influent quality. Then, the research progress on the coupling of electrodeposition with other electrochemical methods, membrane process, ultrasound, adsorption/extraction and other processes was further summarized. Finally, the problems and challenges of metal recovery by electrodeposition were discussed, and the future development direction of metal recovery by electrodeposition was put forward.更多还原
