Abstract

By the coagulation-flocculation jar test, the PAC adsorption property and coagulation removal property of Atrazine and Chlorothalonil, and influence on removal effect of Atrazine and Chlorothalonil by PAC Adsorption and Enhanced Coagulation in combination have been acknowledged, with different doses of PAC or polyaluminium chloride. The results of test showed that PAC can absorb Atrazine and Chlorothalonil effectively, and that the removal effect of the enhanced coagulation for Atrazine and Chlorothalonil is affected by coagulation effect. Enhanced coagulation cannot remove Atrazine effectively, while it can remove 75% of Chlorothalonil. PAC adsorption and enhanced coagulation in combination can remove Atrazine and Chlorothalonil effectively. For the initial concentration of 0.1 mg/L of Atrazine, dosage of 60mg/L of PAC and 20mg/L polyaluminium chloride can reach more than 98% removal efficiency, and make treated water standard. For the initial concentration of 0.1 mg/L of Chlorothalonil, dosage of 20mg/L of PAC and 20mg/L polyaluminium chloride can reach more than 90% removal efficiency and make treated water up to standard.
