Abstract

The effectiveness of enhanced coagulation of polluted surface water with high organic contents by permanganate composite chemicals has been studied through laboratory jar test. It shows that permanganate composite chemicals oxidation greatly enhances the coagulation of the water,resulting in obvious reduction of residual turbidity of settled water. The oxidation of permanganate composite chemicals widens the optimal dosage range of coagulant and improved the stability of treated water quality. The relationship between the optimal dosage of permanganate composite chemicals and the CODMn of raw water is a double rectangular hyperbola y=4.854x/(25.527+x).
