Abstract

Abstract:

The electrochemical method for the treatment of wastewater containing organic pollutants has attracted a great deal of attention. The combination of electrochemical reaction and chemical catalysis to activate organic molecules by the electrocatalytic electrode results in their electrical catalytic degradation. In recent years,considerable attention has been paid to particular electrodes because of the increased electrolysis efficiencies. The appropriate choice of electrode material and the use of particle group electrode are effective for the acceleration of electrochemical reaction rate and for the enhancement of electrochemical promotion of catalysis,which favours electrochemical conversion of organics for wastewater treatment. In this paper two important considerations are reviewed:the scientific basis for the selection of electrode materials and the prospects for the use of particle group electrodes.

Key words: wastewater, organic pollutants, electrochemistry, particle group electrode, catalysis

摘要：

电化学方法处理含有机污染物的污水已引起广泛的兴趣。在电催化电极的作用下,电化学反应和化学催化作用结合,导致有机分子的电催化降解。由于粒子群电极可以提高电解效率,所以近年来受到相当的关注。选用合适的电极材料和采用粒子群电极可以加速电化学反应速率和增进电化学对催化作用的促进作用,因而在有机污水处理中它们将有助于有机物的电化学转化反应。其中论述了两个重要的问题:电极材料选择的科学依据和粒子群电极的应用前景。
