| Summary: | 碩士 === 國立雲林科技大學 === 化學工程與材料工程系碩士班 === 101 === In this study, the electrochemical / persulfate oxidation procedure of organic substances contained in the TNT wastewater system removal study was diluted with deionized water to 20 times the processing of waste acid trinitrotoluene, the organic matter concentration of about 180mg / L。Studies have shown that the electrochemical / persulfate oxidation process to remove organic matter in wastewater trinitrotoluene process when the electrode potential 6 volt, the reaction temperature is 45 ℃, persulfate concentration of 1.7wt%, pH of 0.5 under operating conditions, experience 21hr after the removal of organics can reach about 90%. Further , the operation of the electrochemical oxidation process the pH effect, persulfate oxidation process to compare the effect of temperature in the electrochemical / persulfate oxidation process with the additive。In the electrochemical oxidation process, the electrode potential 6 volt, reaction temperature 45 ℃, pH = 0.5, after 7hr reaction, in the absence of any oxidants , the mineralization rate can achieve to 33.1%, suggesting oxidizing power of the water from the wastewater, electrolysis into oxygen, thereby generating hydrogen peroxide. The electrochemical / persulfate oxidation process at potentials 6 volt, reaction temperature 45 ℃, pH = 0.5, persulfate concentration of 1.7wt%, after a 7hr, the reaction rate of 66.44% obtained mineralization, and electrochemical / persulfate oxidation process, electrochemical oxidation process that is, for a difference of 33.34% sulfate radical generated effect.
This study shows that hydrogen peroxide (H2O2) generation experiments,electrochemical / persulfate oxidation process, the program can generate electrochemical oxidation of hydrogen peroxide (H2O2), generated by hydrogen peroxide to explain the mineralization of organic matter pathways . And electrochemistry / persulfate oxidation process made the experimental results into the Design-Exper this software, the display of this study is a significant effect, in which electrolysis potential, persulfate concentration, pH value of wastewater is also a significant effect.
