In this article,the optimization of coagulation and precipitation process in raw seawater purification process was studied and analyzed by cup-pot experiment.The experimental re-sults showed that the coagulation and precipitation of raw seawater do not need pH value adjust-ment.Under the conditions of flocculation intensity of 45 r/min,precipitation time of 30 min,rapid mixing time of 90 s and flocculation time of 8 min,the coagulation and precipitation treatment of raw seawater is the best.Under the experimental conditions of 30 mg/L FeCl3 coagulant dosage,pH value of 8.03 and precipitation time of 40 min,the turbidity removal efficiency of the coagulant pre-cipitation system can reach 98% and the coagulant precipitation effect is the best.
