摘要
在自制电化学反应器中,以甲基橙模拟染料废水为处理对象,采用Box-Behnken Design响应面法研究了影响阴阳极同时作用电化学法处理染料废水的因素及其交互作用。实验得出各因素对废水脱色率影响的大小顺序为:电流密度> Fe^3+浓度>Cl^-浓度。各因素之间的交互作用对废水脱色率影响的大小顺序为:电流密度和Fe^3+浓度>电流密度和Cl^-浓度>Fe^3+浓度和Cl^-浓度。优化结果表明:Fe^3+浓度为1.02 mmol/L、Cl^-浓度为10.96 mmol/L、电流密度为11.52 mA/cm^2时,最佳脱色率为94.67%。阴阳极同时作用电化学法对甲基橙去除效果显著。
In a self-made electrochemical reactor,Box-Behnken Design response surface method was used to study the factors and interactions affecting the simultaneous action of anode and cathode on electrochemical treatment of methyl orange simulated dye wastewater.The experimental results show that the order of influence of each factor on wastewater decolorization rate is as follows:current density>Fe^3+concentration>Cl^-concentration.And the order of influence of the interaction between various factors on wastewater decolorization rate is as follows:current density and Fe^3+concentration>current density and Cl-concentration>Fe3+concentration and Cl^-concentration.The optimization results show that when Fe3+concentration is 1.02 mmol/L,Cl^-concentration is 10.96 mmol/L and current density is 11.52 mA/cm2,the optimal decolorization rate is 94.67%.Electrochemical method with simultaneous action of anode and cathode has a significant effect on removal of methyl orange.
