Open publisher page 2 citations

Abstract

Fenton reagent is utilized to pre-treat AN wastewater with high concentration.The effects of some factors on the degradation of AN are investigated,such as pH value,concentration of Fe~(2+) and H_2O_2,initial concentration of AN,temperature,adding mode of H_2O_2,concentration of UV and C_2O~(2-)_4 and so on,and the functioning mechanisms of different factors are analyzed.The results show that the residue rate of AN decreases below 20% and the synergistic effect of UV and C_2O~(2-)_4 on Fenton reagent is good when the concentration of AN stays at 300mg/L with 400mg/L Fe~(2+) and H_2O_2 respectively and reaction time 15mins.
