Abstract

Yellow River reservoir water, which is slightly polluted and owns a high content of suspended particles, is studied as raw water in this paper. Online particle counting instrument is used to detect and track the particle content of raw water. Potassium permanganate pre-oxidation process combined with DAFF(dissolved air flotation filtration ) is studied to examine the effect of removing contaminants. The results showed that the particles with the size of 2 m,3 m and 5 m take up the major part, and the ratio reduce with the increase of the size. As the water treatment proceed, the concentration changes and the changing law differs from size to size. The effect of removing suspended particles is obvious, with the removal ratio over 90%. The outflow’s NPOC is 1.388 mg / L on average, and the average removal rates is 49.1%. The combined process also improved the effect on water taste and disinfection byproducts significantly.
