Abstract

For controlling water eutrophication and decreasing total phosphorus (TP) in effluent of wastewater treatment plants, chemical phosphorus removal was studied. Results showed that the optimal FeCl₃•6H₂O and polyaluminium chloride (PAC) dosage were 20 and 10 mg L^-1, respectively, and the reaction time was 15 minutes. Under this condition, the TP concentration was 0.24 and 0.23 mg L^-1, respectively. No matter adding PAC or FeCl₃•6H₂O, their suspended (SS) and residual metal salts were 2 and 0.15 mg L^-1. The effect of chemical phosphorus removal process on the concentration of COD and NO₃ ^--N showed that the removal efficiency of COD was 45.5% and NO₃ ^--N was only 3.1% when PAC was phosphorus removal agent. However, the efficiency of COD was 34.8% with FeCl₃•6H₂O adding.
