摘要
综述了工业废水电化学处理技术的进展和应用。介绍了电化学氧化、电化学还原、电絮凝、电气浮、电渗析等方法。阐述了电化学氧化技术目前没有工业化的主要原因是低的电流效率、高能耗和大的操作费用,如何提高传质特性、电流效率、开发用于废水处理的高效电解槽是亟待解决的问题。特别指出了未来工业废水电化学处理技术的发展方向是生物难降解废水处理用的阳极材料、电化学反应器、电化学组合技术、生物膜电化学反应器工艺。
This article reviews the development and applications of electrochemical technologies in industrial wastewater treatment. Electrochemical oxidation, electrochemical reduction, electrocoagulation, electroflotation, electrodialysis are described. But so far, electrochemical technology has not been commercialized because of low current efficiency, high-energy consumption and high operating costs. Consequently, how to enhance mass transfer characteristics and to increase current efficiency, develop highly efficient electrochemical cell for wastewater treatment is still a very urgent problem. Particularly, it is indicated that anodic materials for bio-refractory wastewater treatment, electrochemical reactors, combined electrochemical methods, biofilm-elctrode process will be the directions of electrochemical processes of industrial wastewater treatment in the future.
