Through a static beaker test, it was analyzed the effect on the removal of turbidity and UV254 by poly-aluminum chloride(PAC) under different dosages and pH values in the PI river,and discussed the relationship between the dosage of PAC and residual aluminum.The results showed that it has good effect on removing turbidity by adding PAC,but it was normal to UV254,the removal rate was not exceed sixty percent, with the increase of PAC dosage, the removal trend of the turbidity after precipitation was similar to that of UV254, while residual aluminum first decreased and then slowly increased.For turbidity removal, the optimal dosage of PAC was 8.5 mg / L, and the optimal pH value range was 7.2-8.5. For removal of UV254, the optimal pH value range was 6.5-7.2. The best experimental conditions for coagulation are PAC dosage of 8.5 mg/L, raw water pH value of 7.2.
