三维电极法处理含油废水的研究进展

Research Progress of Oily Wastewater Treatment by Three-Dimensional Electrode Method

含油废水是一类较难处理的工业废水,传统的处理方法难以满足废水净化的经济和技术要求。三维电极法作为含油废水一种新型电化学处理法,具有面积体积比大、传质效果好和电流效率高等优点,在含油废水处理领域应用越来越广泛。阐述了三维电极的含义、分类、电流分布和污染物的降解机理等基本内容,着重介绍了三维电极的主电极和填充粒子电极材料及三维电极在含油废水处理方面的研究进展,指出了三维电极法目前存在的问题以及今后的研究方向。

In the treatment of oily wastewater,traditional methods can hardly satisfy the economic and technical requirements of wastewater purification. Three-dimensional electrode method refers to a new electrochemical treatment which owns the advantages of large area-volume ratio,high mass transfer rate and high current efficiency,and it is widely applied in the field of oily wastewater treatment. In the paper,its meaning,classification,current distribution and pollutant degradation mechanism were elaborated; its main electrode,particle-filled electrode material and research progress were emphatically presented; and its current existing problems and future research direction were pointed out.
