Degradation Model of Phenol and Concentration of • OH Based on TDE Treatment Method

摘要

In this paper, it is analyzed about mechanism of TDE (three dimensional electrode) reactor; the degradation of pollutant obeys fist order reaction and velocity or effect is controlled by coefficient km during reaction process. Because of the function of semiconductor and electrochemistry catalysis, oxida-nts of hydroxyl radicals and chlorine, which have high effect on phenol, produce in the reactor. Concentration of • OH can be calculated by reaction equation. The process of phenol degradation is dominated by effect of hydroxyl radicals and there are only carbon dioxide and water produce during the reaction.
