Study on the Flocculation Treatment of Simulative Dyeing Wastewater by the Dicyandiamide Formaldehyde Polymer

Abstract:

The laboratory-made dicyandiamide formaldehyde polymer is used to study the effect of the flocculation treatment of simulated wastewater of You Li Su-hong EB. And the influencing factors mainly include flocculant dosage, pH and temperature. The experimental results show that when the dicyandiamide formaldehyde flocculant dosage is 8mL / L and pH is acidic or neutral, COD and color removal rate are the highest that have reached more than 70%. Besides, temperature has little effect on the flocculation treatment, and room temperature is enough to make the treatment effect good. Finally compared with the commonly used flocculant PAC, dicyandiamide formaldehyde polymer treatment effect is better with less addition.
