摘　　要：污水含油直接制约污水生化处理效果,气浮除油是一种广泛采用的方法。比较了不同气浮方法的优缺点,总结了电解气浮、散气气浮、溶气气浮、涡凹气浮,以及聚结+气浮、气浮+磁分离、旋流+气浮组合工艺的除油效果及应用现状,指出了气浮工艺的发展方向。Sewage including oil will directly restrict the effect of biochemical treatment, and air flotation is a widely used method for oil removal. The advantages and disadvantages of different styles of air flotation are compared. The oil removal effect and application status of electro-flotation, induced air flotation, dissolved air flotation, cavitation air flotation, coalescence ＋ air flotation, flotation ＋ magnetic separation, and rotational flow ＋ flotation are summarized, with development direction of the air flotation process pointed out.
