Descrição: The common chemical flocculation process was summarized according to the oily sludge treatment process, and the different main flocculation mechanism and the superiority and the limitation were analyzed. The conclusion is that all of these factors such as adsorption bridge, volume sweep the trap, electrical neutralization, extracellular polymer bridging and other mechanisms have come together to make flocculants possess excellent flocculation performances. In addition, modification, recombination and compounding of the flocculants can cause many flocculation mechanisms, which is of great significance for the synthesis of high efficient sludge flocculants. Finally, the complexity of oily sludge flocculation process was point out. Further research on specific action mode and mechanism and main factors affecting flocculation will be helpful to the extensive application of oily sludge flocculant.
