Pilot-plant test of air-flotation flocculation treatment for refinery sewage
Abstract：Air-flotation flocculation treatment is an important step and isvital to ensure successful operation for treatment process of refinery sewage.Development and selection of good flocculants is important pledge to incr ease 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 CODCr reducing efficiency >55%,and Oil >75% ,are obtained.Air-flotation effluent quality is completely suited to biochemica l treatment.
