摘要
采用电化学氧化法处理酸性染料废水,考察了反应时间、电流密度、反应pH值、极板间距等因素对染料废水中污染物的去除效能的影响。结果表明,以IrO2-SnO2-TiO2/Ti极板为阳极,以钛网极板为阴极,在电流密度为8.0 A/dm2,pH值为6.0,极板间距为30 mm的条件下,反应120 min后CODCr和氨氮的去除率分别为71.88%、100%。电化学氧化法是处理酸性染料废水的一种高效稳定的方法。
Electrochemical oxidation process was used to treat acid dye wastewater, the influences ot reaction time, current density, pH value, space between electrode plates and some other factors on pollutants removal were investigated. The results showed that, with IrO2-SnO2-TiO2/Ti electrode plate as anode, titanium mesh as cathode, the removal rates of CODcr and ammonia nitrogen reached 71.88% and 100% respectively after 120 min of reaction under the condition that the current density was 8.0 A/dm2, the pH value was 6.0 and the space between electrode plates was 30 ram. Therefore, electrochemical oxidation is an effective and stable process for acid dye wastewater treatment.
