Study on Pharmaceutical Wastewater Pretreated by Chemical Coagulation Method

Abstract:

This study took three factors three levels orthogonal experiment scheme and chose PAM as the coagulant, pretreated a pharmaceutical factory wastewater by chemical coagulation method, and the results indicated: when coagulant dosage was 50 mg/L, pH was 5 and mixing time was 20 minutes, the removal efficiency of SO₄^2- and COD could be 39.0% and 72.5% respectively. The water quality could meet the requirements of the subsequent treatment processes.
