摘　　要：采用Mg(OH)2对活性艳红染料废水进行脱色处理,研究了镁盐投加量、pH值、反应时间和反应温度等因素对脱色效果的影响。结果表明,镁盐对活性艳红染料具有良好的脱色效果,在镁盐投加量为200mg.L-1,pH值为11.5,反应时间为10m in,反应温度为20℃的条件下,脱色率可达97.9%。Decoloration of wastewater containing reactive brilliant red dye by using magnesium hydroxide was studied. The effect of magnesium salt dose, pH value, treatment time and treatment temperature were investigated. The results showed that the magnesium salt had an excellent performance in deeoloration of the wastewater. The deeoloration rate can up to 97.9% with 200mg · L^-1 magnesium hydroxide, pH value is 11.5 , 10min treatment time and 20℃ treatment temperature.
