三维电极法粒子电极制备及对苯酚废水的处理研究

Particle Electrodes Preparation and Phenol Removal Research in Three-dimensional Electrodes Reactor

电化学法是近年来一种备受关注的处理含酚类难生物降解有机废水的方法,实验制备了ZnO、CuO、Fe2O3掺杂的炭气凝胶作为粒子电极,进行了三维电极法处理苯酚模拟废水试验,考察了几种粒子电极材料对苯酚的去除效果。研究表明,在相同的处理条件下,ZnO掺杂的炭气凝胶作为粒子电极对苯酚的去除效果最好。

Electrochemical treatment is a promising alternative for the treatment of phenolic waste water. Electrocatalytic oxidation of phenol was investigated in the presence of ZnO,CuO,Fe2O3 supported on carbon aerogel as particle electro des. Special attention was paid to experimentally probe the performance of pheno l removal in the process of repeated batch runs. The experimental results showed that, at the same conditions, ZnO dispersed carbon aerogel, as particle electro des could remove phenol-containing wastewater much more efficiently than other p article electrodes.
