| Abstract: | A novel flocculant decolorant DF was synthesized by using formaldehyde, ammonium chloride, dicyandiamide, urea and thiourea as raw materials. It was used to treat dyeing and printing wastewater incorperating with other reagents. The experimental results showed that DF exhibited significant effect for decolorization of anionic dyeing and printing wastewater. The removal ratio of chroma was up to 60% at a time and that of COD was also up to 60%. |
