| Abstract: | In this paper, the mechanism of TDE reactor is analyzed; the degradation of pollutant obeys linear form and velocity or effect is controlled by coefficient k m during reaction process. Because of the function of semiconductor and electrochemistry catalysis, oxidants of hydroxyl radicals and chlorine, which have high effects on phenol, can be produced in the reactor. The process of phenol degradation is mainly dominated by effect of hydroxyl radicals and there are carbon dioxide and water produce during the reaction. |
