摘要

The removal of COD and color present in dye manufacturing process wastewater were studied using the photo-Fenton oxidation process. Emphasis of this study was placed on the effects of UV light intensity, ferrous and peroxide dosages, and the pH value on the process performance. Around 76/100 and 93/100 removals of COD and color can be achieved, respectively, under the experimental condition of this study. Applying relatively higher UV power was found to accelerate the removals remarkably, the enhanced effect becomes more and more significant as reaction carries on. The presence of ferrous ions enhanced the removal rate greatly during the initial reaction period, and after a certain time point the removal profiles became leveling off due to the lack of H_2O_2 residue in the reaction mixture. An excess of H_2O_2 does not necessarily result in relatively higher removals of COD and color. As for the pH effect, the values of pH=3 and 4 were found optimum for the removals of COD and color, respectively. According to this study, the photo-Fenton process can be considered as a promising technology for the treatment of dye manufacturing process wastewater.
