摘　　要：针对碳气凝胶电极电吸附除盐工艺去除硝酸盐过程中存在的问题,采用电解水催化还原工艺作为其后续工艺,在原碳气凝胶电吸附除盐工艺装置上,进行了一系列平衡试验,对其影响因素进行了研究。结果表明,可以在不增加任何设备的情况下,大幅提高碳气凝胶电极电吸附除盐工艺去除硝酸盐的效果,并使电极得到再生。The water electrolysis catalytic reduction process was employed as the subsequent process of electrosorption desalination to resolve its existing problems in nitrate removal. A series of equilibrium experiments were carried out to study the influencing factors. The tests results indica- ted that, as a subsequent process, the water electrolysis catalytic reduction process could improve the nitrate removal efficiency greatly and regenerate the electrodes without any additional equipments.
