| 摘 要： | 文章在铝阳极和不锈钢阴极的电化学体系中，在恒电流模式下，考察了．活性生红M-3BE模拟废水脱色过程及能耗的影响因素。实验结果表明，电流密度、电解液初始pH值、氯化钠电解质浓度、温度、染料浓度对染料溶液脱色效率影响较大；电流密度、电解液初始pH值、氯化钠与硫酸钠电解质浓度、温度对脱色过程能耗影响显著。在一定实验条件下，染料溶液脱色率可达到98％，能耗117．75kwh／（kg dye）。在不同pH的范围内，活性红M～3BE表现的脱色机理不同，pH4～8为混凝与阴极还原脱色共同作用，pH小于4和大于9则表现为阴极还原脱色为主，且低pH下能耗较低。氯化钠既有助于提高染料废水的脱水效率，又有助于降低脱色过程中的能耗。

| Abstract: | To further clarify the mechanism of decolorization of reactive dye and power consumption in the electrochemical system with soluble anode,influence factors on decolorization of C.I.Reactive Red M-3BE simulated wastewater were researched under galvanostatic model and using Al as anode and stainless steel as cathode.The experimental results have shown that the decolorization of the dye is strongly affected by current density,initial pH,temperature,concentration of dye and NaCI,and power consumption strongly affected by current density,initial pH,temperature,concentration of Na2SO4 and NaCI.Under certain experimental conditions,the decolorizing efficiency and power consumption of the dye simulated wastewater is 98%,117.75 kWh/(kg dye),respectively.The decolorizing mechanism of the dye is different in the different range of pH,coagulation and cathodic reduction filled the role of decolorization in the range of pH 4~8,and cathodic reduction predominated in the range of pH<4 or >9.The power consumption is lower in pH<4.The addition of sodium chloride can not only enhance decolorizing,but also be contributed to reduce energy consumption. |
