Abstract:The composite coagulant of PFS-PDM —was prepared by polyferric sulfate and poly (dimethyldiallylammonium chloride). The enhanced coagulation treatment of micro-pollution Liuxi River water was studied with the composite coagulant of PFS-PDM. The treatment efficiency of the Liuxi River water with PFS and PFS-PDM were compared and analyzed. The experimental results showed that the removal efficiency of turbidity, UV254, and algae from micro-polluted source water by the composite coagulant was higher than PFS. The removal efficiency of turbidity, algae and UV254 increased by 22.1%、19.5% and 14.9% respectively when PFS-PDM dosage was 3mg/L. The composite coagulant showed better enhanced coagulation performance.
