摘要: 采用Ti/IrO2电极间接阳极氧化处理活性黑5模拟废水,主要研究pH值、电压、电解时间及NaCl投加量对其降解效果的影响。结果表明,在pH值为3,电压20 V,电解时间60 min,NaCl投加量2.5 g/L的条件下,该染料的降解率及脱色率均达到100%,苯环结构的降解可达45%,COD去除率可达60%。并对该染料的降解规律进行了初步探讨。Abstract: The treatment of simulated wastewater containing Reactive Black 5 was carried out by indirect anodic oxidation with Ti/IrO2 electrode. The influences of pH value, voltage, electrolysis time and NaCl dosage on the degradation performance were studied. The results show that the removal and decolorization rate of the dye are both 100%, the removal rate of aromatic ring is 45% and COD removal rate is 60%, under the following conditions:pH=3, voltage=3 V, electrolytic time=60 min, NaCl=2.5 g/L. Finally, the degradation law of the dye was investigated preliminarily.
