| Abstract: | Air flotation flocculation treatment is an important step and is vital to ensure successful operation for treatment process of refinery sewage.Development and selection of good flocculants is important pledge to increase treatment effectiveness of air flotation.Mixed flocculants composed of inorganic and organic flocculants are applied to pilot plant test of refinery sewage.Feeding dosages,interval time and way of mixed flocculants were determined.The satisfactory results,such as COD Cr reducing efficiency >55%,and Oil >75%,are obtained.Air flotation effluent quality is completely suited to biochemical treatment. |
