摘　　要：目的确定混凝气浮法处理乳化液废水的最佳奈件．方法采用全溶气流程，通过改变试验过程絮凝剂投加量、pH值、絮凝时间、搅拌强度、气浮时间、气浮压力，考察其对处理效果的影响．结果混凝气浮试验中混凝药剂采用聚合氯化铝铁（PAFC）投药量为1000mg／L，pH值在7～8．5，絮凝时间为5min，转速为250r／min，气浮时间为20min，气压为4kg·cm^-2对浊度的处理效果最好，达到99％以上．结论混凝气浮法是一种有效处理乳化液废水的工艺，有效地控制运行条件可以达到较高的去除效果，可以节省基础投资及能耗．The purpose of this article is to find out the best optimum condition of coagulate flotation process to treat oil emulsion wastewater. A coagulate flotation process is used and the flocculant input, pH, and reaction time are changed to examine the processing effects. The results show that when the input of PAFC is 1 000 mg/L,pH is 7 - 8.5, flocculation time is 5 minutes, rotation speed is 250 r/min, flotation time is 20min, reaction press is 4 kg/cm^2, the removal rate of turbidity can reach more than 99%. So coagulate flotation process is an effective craft to treat oil emulsion wastewater, and a higher removal rate can be got within an effective optimum condition. Meanwhile this is a process with low investment and energy consumption.
