摘要
A Trimethoxysilane modified polymer flocculant (PMCAD) was synthesized and applied in wastewater from effluent A/O bioreactor. The turbidity removal, color removal and zeta potential of flocculant PMCAD were determined through the treatment of coking wastewater from A/O bioreactor. Results showed that flocculant PMCAD was more efficient for turbidity removal than that of PAM. The largest removal rates of turbidity and color were 94.44 % and 67.78 % respectively at the dosage PMCAD of 200 mg/L at pH 7. the zeta potential of flocs for coking wastewater increased as the PMCAD dosage increased from 100 to 600 mg/L at pH 7.
