实验利用ACF作为阴极，以酸性大红3R染料为模拟废水，通过静态实验研究电流密度、曝气量、电解质浓度以及初始pH值对废水色度去除效果的影响。结果表明：ACF作阴极有很强的吸附能力，氧在阴极表面被还原成H2O2等氧化性物质，对染料的有很强的降解能力，这远好于不锈钢阴极；较低的操作电流密度有助于降低处理成本；电解质浓度和曝气量并不是越大越好，遵循一定的规律；处理效果受初始pH的影响较大，在酸性条件下染料废水的脱色效果好于碱性条件。利用ACF电极在电流密度为6 Am/cm2，电解质浓度为0.04 mol∙L−1，曝气量为0.2 m3/h，初始pH值为3.5条件下处理酸性大红3R废水70 min，废水脱色率可达95.30%。
By using ACF as the cathode, acid scarlet 3R as simulated wastewater, the experiment researches into the effect of current density, aeration, electrolyte concentration and the initial pH value on the color removal of wastewater. The results showed that: ACF cathode has a strong adsorption capacity. Oxygen is reduced to H2O2 and other oxidizing substances H2O2 on the cathode surface. Therefore, it has a strong degradation capacity to dye, which is far better than that of the stainless steel cathode; lower operating current density helps reduce processing costs; higher electrolyte concentration and aeration is not necessarily better, which follows certain rules; the treatment is effected greatly by the initial pH, and the effect of decolorization in the acidic conditions is better than that in alkaline conditions. When the current density is 6 Am/cm2, electrolyte concentration is 0.04 mol∙L−1, aeration capacity is 0.2 m3/h, initial pH is 3.5 and the time of treatment is 70 min, the decolorization rate of wastewater is 95.30%.
