摘要：The source water of Ganzhou Sanshui Plant mixes the water of Zhangjiang River and Fengshan Reservoir to change the water quality of the source water, which makes the water treatment more difficult and the sedimentation tank runs away. In order to ensure the water quality of the factory water in the case of changes in water quality, the coagulation effect of three common coagulants was studied by a beaker test, and pre-oxidation was carried out using potassium permanganate. The results show that the organic matter in the source water is mainly humic acid. With the increase of coagulant dosage, the residual turbidity showed a gradual decline. When the dosage exceeded 40 mg/L, the system showed some degree of turbidity. With the increase of potassium permanganate dosage, the turbidity removal rate showed a gradual increase trend. When the dosage reached 0.7 mg/L, the continuous increase of KMnO₄ dosage did not significantly improve the turbidity removal. Under the condition that the coagulation effect is optimal, 0.5 mg/L potassium permanganate can significantly improve the sedimentation of flocs and reduce the turbidity of water after sinking.
