Effect of Biochemical Organics on Pretreatment of Dye Wastewater by Flocculation

Abstract:

Effect of the presence of acetic acid on the pretreatment of dye wastewater by flocculation was studied. The effects of pH, PAC and PAM dosage on the flocculation of dye wastewater containing acetic acid were studied, with the dye wastewater without acetic acid as the blank. The results showed that the optimal pH of the dye wastewater with acetic acid by flocculation was 8, and that of the dye wastewater without acetic acid was 6, but the COD_Cr removal efficiencies were no significant difference. The best dosage of PAC and PAM of dye wastewater containing acetic acid was 4g/L and 0.15mg/L respectively. The presence of acetic acid was no influence on the flocculation treatment of dye wastewater. Then the effect of different concentrations of dye wastewater containing acetic acid on the flocculation treatment was followed. The results showed that the treatment effect increased with the increase of wastewater concentration.
