Research on PFS coagulating treating the ceramic wastewater

PFS coagulation sedimentation method of high concentration ceramic wastewater. As turbidity, absorbance removal, conductivity haracterization to determine the PFS reagents. Comparison of different reaction conditions, the turbidity removal, color removal, conductivity, optimal operating conditions to determine the dosage of PFS. Experiment, the ceramic waste water 300 mL, stirring time for 5 mins, settling time is 30 mins, first set the PFS amount of 500-2000 mg / L, then the more the amount of PFS, the worse the treatment effect; then set the amount of PFS 40-280 mg / L, the amount of PFS in the 100-130 mg / L, treatment is better; the last set PFS amount of 100-130 mg / L, PFS determines the most appropriate dosage, and the results show that, PFS appropriate dosage of 105 mg / L, turbidity removal rate of 93.8%, 98.0% removal rate of absorbance, electrical conductivity of 92.7%.
