摘要: 在引气浮选中,影响除油效率的因素主要是油粒直径、气泡直径和油粒表面的化学性质。加
入表面活性剂、聚合物及无机物凝聚剂,可以降低气泡直径、增大油粒直径、降低油粒表面的电位,从而提高除油效率。

Abstract: In induced gas floatation,the factors that influence oil removal efficiency are oil droplet size,bubble size and the chemical properties of the oil-drop surface. The surfactants,poly-mers and inorganic coagulant can be added to reduce the bubble size and the electric potential of the oil-drop surface,and to increase the oil droplet size,thus improving the oil removal efficiency.

Key words: Oily sewage, Oil water separation, Surfactant, Polymer
