摘要
采用UV/Fenton氧化处理难降解腈纶废水,研究了Fe2+和H2O2的投加量、pH值、光照时间、光照强度、有机物的浓度等条件对降解腈纶废水效果的影响。通过实验得出了UV/Fenton试剂氧化处理腈纶废水的最佳反应条件为:原水样pH3,Fe2+浓度为10mmol·L-1,H2O2浓度为20mmol·L-1,紫外光照强度为1000W(λ=365nm),光照时间为50min,COD降解率最高达62.77%。
The principals and reaction conditions of acrylic effluent disposal with photo-Fenton＇s oxidation reaction are studied . This experiment reviewed the effect of different Fe^2＋ and H2O2 concentration, pH, illumination time, light intensity and the concentration organic compounds. According to this research, the optimal reaction conditions for the disposal of acrylic effluent using UV/Fenton method were found ： the pH value of wastewater sample is 3 approximately, the concentration of Fe^2＋ is 10 mmol · L^-1 , the concentration of n202 is 20 mmol · L^-1 , the light intensity of Ultraviolet is 1 000 W（with λ =365 nm）, and the illumination time is 50 min. The degradation efficiency of COD is 62.77%.
