摘　　要：以双氰胺和甲醛为主原料,在添加改性剂的条件下制备了改性双氰胺-甲醛缩聚物,并直接与硫酸亚铁复合成脱色絮凝剂;以活性艳红X-3B染料废水的脱色率和CODCr去除率为考核指标,探讨了硫酸亚铁投加方式、复合质量比、pH等因素对活性艳红X-3B处理效果的影响。研究结果表明,在一定投加量下,复合脱色絮凝剂处理活性艳红X-3B染料废水的脱色率和COD去除率分别为99%和约75%左右。Modified dicyandiamide-formaldehyde,a flocculating-decolorizing agent,was synthesized by using dicyandiamide(DCD),formaldehyde(HCHO)and add modifier.Under certain conditions,without a separation directly with ferrous sulfate reaction,the composite flocculate decolorizing agent was synthesized,for study on reactive red X-3B dye wastewater flocculation.The effect of the composite mass ratio,pH and other factors on reactive red X-3B treatment were assessed with the decolorization rate and the CODCr removal eff...
