摘要
利用光敏电芬顿法降解高浓度、高盐分的有机废水(以硝基苯为例),考察FeSO4浓度、草酸钾浓度、电流强度、初始pH对硝基苯降解效果的影响。结果表明:采用紫外光光敏电芬顿法处理硝基苯废水时,盐分耐受度高,降解速度快。最佳降解条件为FeSO4浓度4.5 mmol/L,草酸钾浓度3.0 mmol/L,电流强度1.5 A,初始pH为2,处理1.5 h后,硝基苯的去除率可达93%。
UV-sensitized electro-Fenton technique was used to treat the simulated nitrobenzene wastewater with high salinity.The effects of the FeSO4 and K2C2O4 concentration,current intensity and initial pH value on the nitrobenzene removal efficiency were investigated.Results showed that the simulated nitrobenzene wastewater was rapidly degraded by UV-sensitized electro-Fenton treatment.The optimal conditins were as follows：FeSO4 concentration of 4.5 mmol/L,K2C2O4 concentration of 3.0 mmol/L,current intensity of 1.5 A,and initial pH value of 2.The removal efficiency of nitrobenzene reached 93% in 1.5 h under the optimal conditions.
