摘　　要：以某港口含油污水处理厂二级气浮出水为研究对象,探究曝气-高锰酸钾强化混凝-陶瓷膜微滤组合工艺对含油废水中油和有机物（COD）的去除效能,重点考察曝气时间、高锰酸钾投加量、投加方式等因素对处理效果的影响。结果表明,最佳曝气时间为40 min,高锰酸钾投加量2 mg/L,投加方式为在混凝剂PAC前投加;组合工艺对油和COD总的去除率可达到91%~94%;此外,曝气和高锰酸钾强化混凝处理过程能够减缓跨膜压差的增长速率,延长陶瓷平板膜的使用寿命。To a port of oily wastewater treatment plant secondary flotation effluent as the research object, aeration and potassium permanganate inquiry of strengthening coagulation flocculation - ceramic membrane microfiltmtion combination process of oil in the oily wastewater and organic matter （COD） removal efficiency, with emphasis on the effect of aeration time, potassium permanganate dosage and dosing mode and factors on the treatment effect. Test results show that the optimum aeration time is 40 min, potassium permanganate and 2 mg/L, adding way before coagulant PAC dosing; combined process of oil and COD the total removal rate can reach 91%-94%; In addition, aeration and potassium permanganate enhanced coagulation process can slow down the growth rate oftrans membrane pressure, prolonging the service time of the plate ceramic membrane.
