Fe/Fe电凝聚法处理模拟染料废水的影响因素
|
摘要
应用Fe/Fe为反应阴阳电极,选择活性艳蓝模拟废水作为处理对象,以脱色率和能耗为考核指标,对电凝聚法处理活性艳蓝染料模拟废水的脱色行为进行研究。结果表明:在初始pH值为5.5,溶液的搅拌速率为400 r/min,电压为6 V,电解质Na_2SO_4浓度为0.01 mol/L,极板间距为1.0 cm的条件下,使用染料质量浓度为500 mg/L的模拟废水反应35 min,在10 min时活性艳蓝的脱色率达到99%以上。研究表明:以Fe/Fe电极通过电凝聚法对活性艳蓝模拟废水进行脱色处理是可行且高效的。
Taking Fe/Fe as the reactive anode and cathode, choosing simulated reactive brilliant blue wastewater as the treatment object and taking decolorization rate and energy consumption as the assessment indexes, de-colorization behavior of simulated reactive brilliant blue dye wastewater by eletro-coagulation method was studied in this paper. The results indicated that the initial pH value of the simulated wastewater, the stirring rate of the solution, the voltage, the electrolyte Na_2SO_4 concentration and the spacing between two electrodes had influence on removal of the reactive bright blue. Experiment showed that: under the condition that the initial pH value was 5.5, stirring speed of the solution was 400 r/min, the voltage was 6 V, electrolyte Na_2SO_4 concentration was 0.01 mol/L, the spacing between two electrodes was 1.0 cm, and the dye concentration was 500 mg/L, with 35 min's reaction time, the decolorization rate of reactive brilliant blue was up to above 99% at 10 min. The study showed that the de-coloration treatment of simulated reactive brilliant blue wastewater with Fe/Fe electrodes by electro-coagulation method was feasible and efficient.
