摘　　要：随着社会的快速发展、工业企业污水的不达标排放,导致全球范围的地下水污染越来越严重,尤其是硝酸盐污染日益突出。电化学法具有对环境友好、反应速率快且操作简便等优点受到广泛关注。本研究通过极化铁丝网强化铁阴极构建三维强化电化学系统,探究不同阴极(铁板和铁丝网)、不同阳极(钌铱钛板与钌铱钛网)、传统电化学系统及三维电化学体系中硝酸盐去除能力的变化,并在构建的三维强化电化学系统中研究了铁丝网的放置位置、数量和电解质的添加量等因素对硝酸盐去除效率的影响。结果表明:以铁丝网作阴极、钌铱钛网作阳极构建的三维强化电化学系统中硝酸盐的去除效率高达100%,且副产物积累极少。With the rapid development of society and the substandard discharge of wastewater from industrial enterprises,groundwater pollution has become increasingly serious worldwide,especially nitrate pollution.Electrochemical method has attracted extensive attention due to its advantages of environmental friendliness,fast reaction rate and simple operation.In this study,a three-dimensional enhanced electrochemical system was constructed by strengthening the iron cathode with polarized wire mesh.The changes of nitrate removal capacity in different cathodes(iron plate and iron mesh),different anodes(ruthenium iridium titanium plate and ruthenium iridium titanium mesh),traditional electrochemical system and three-dimensional electrochemical system were explored.In the three-dimensional enhanced electrochemical system,the effects of the location and quantity of the wire mesh and the addition amount of electrolyte on nitrate removal efficiency were studied.The results show that the removal efficiency of nitrate in the three-dimensional enhanced electrochemical system with iron mesh as cathode and ruthenium iridium titanium mesh as anode is up to 100%,and the accumulation of by-products is very small.
