Abstract
Effects of the sorts and concentration of flocculants, types of PAM and pH value on the advanced treatment of Vitamin E production wastewater by magnetic flocculation process were studied. When the effective flocculant prepared in our lab was chosen as the flocculating agent and its concentration was 1.0 g/L, The cationic PAM 802 was as the coagulant aid and its concentration was 15 mg/L, pH was controlled as 9.0, CODCr removal rate achieved the maximum of above 31%.
