Abstract: The Photoelectro-Fenton(PEF) apparatus has been established by means of TiO₂/Ti as anode,activated carbon fiber(ACF) as the cathode,Fe plate as the inductive electrode,under UV light irradiation,and the response surface method(RSM) used for investigating its decolorization capability for actual printing and dyeing wastewater. The results show that the order of factor significance is as follows:initial pH > reaction time > current density > aeration rate. The regression of mathematical model is comparatively good. The decolorization rate predicted by the model is 98.51%,when the initial pH is 4.52,reaction time 130.37 min,current density 7.47 mA/cm² and aeration rate 1 579.96 mL/min. Compared with actual values,the error rate is only 1.06%.

摘要： 以TiO₂/Ti为阳极，活性炭纤维（ACF）为阴极，Fe板为感应电极，在紫外光的照射下构建光电-Fenton（PEF）装置，并采用响应面法（RSM）考察其处理实际印染废水的脱色能力。结果表明，各因素显著性顺序为：初始pH > 反应时间 > 电流密度 > 曝气速率，数学模型回归性较好；在初始pH=4.52，反应时间为130.37 min，电流密度为7.47 mA/cm²，曝气速率为1 579.96 mL/min时，模型预测的脱色率为98.51%，与实际值仅有1.06%的误差。
