摘要


采用UV/Fenton试剂降解SDBS阴离子表面活性剂废水,在初始pH为3.0,Fe^2+浓度为0.033mol·L^-1,H2O2分2次投加,总投加浓度为0.89mol·L^-1时,室温下紫外辐射反应30min,SDBS降解率可达89.01%.将UV、Fenton、UV/Fenton 3种体系处理SDBS废水的效果进行比较,发现UV对Fe^2+催化H2O2氧化降解有机废水存在协同作用. The UV/Fentons reagent was used to treat anionic surfactant wastewater such as SDBS. The optimal operating conditions were determined as follows: initial pH=3, c(Fe^2+)=0.033mmol·L^-1,c(H2O2)=0.89mol·L^-1, and UV irradiation of 30min at room temperature. Under these conditions, the removal rate of SDBS could reach 89.01%. Furthermore, the degradation abilities of UV, Fentons reagent and UV/Fentons were compared, and the synergistic effect between UV light and Fentons reagent was analyzed.
