Abstract:
In view of the phenomenon of algae overgrowth in raw water of Handan section of the South-to-North Water Transfer Project in summer, removal efficiencies of chlorophyll-a, turbidity and UV254 by coagulant, activated carbon adsorption and activated carbon loaded with potassium permanganate adsorption were compared in a beaker test. The removal efficiency of raw water pollution index of activated carbon loaded with potassium permanganate was higher than that of coagulant or activated carbon adsorption. When dosage of activated carbon loaded with 0.4 g/L potassium permanganate was 15 mg/L, the best integrated removal effect was obtained, and the average removal rates of chlorophyll-a, turbidity and UV254 in raw water were 77%, 92% and 61%, respectively. Activated carbon loaded with potassium permanganate can increase its iodine value and surface oxygen-containing functional groups, thus enhances the coagulation efficiency.
