【 摘 要 】

This study investigated the treatment of water contaminated with textile dye (Cibacron Red FN-R, reactive red 238) using a UV/H2O2 process. The reaction was influenced by the input concentration of hydrogen peroxide H2O2, pH, temperature, and the concentration of textile dye in the wastewater. Analysis of the experimental results displayed both first order and the second order reactions. The reaction type was found to be of a first order throughout the systems. The removal efficiency of the UV/H2O2 process at optimal conditions and dosage (H2O2 = 25 mg/L, pH = 3, temperature = 20 °C for 50 mg/L dye concentration) were found to be 80.633%, 97.07%, and 99.43% at 60 min, 120 min, and 180 min, respectively with K1 = 0.0293 min-1 and R2=0.9992%. COD removal was also studied for the UV/H2O2 process and found to be 62.5%.
