摘　　要：通过国内某植物油厂废水处理工程实例表明,废水按高低浓度分流处理,采取隔油—厌氧消化—化学混凝—耗氧生化处理工艺,能稳定达到国家要求的排放标准,同时降低工程投资和运行费用。Segmented effluents from a oil-refining plant are treated using a combination process. Oil separation, coagulation, anaerobic digestion and contact oxidation are used as pretreatment for high strength while coagulation, contact oxidation and dissolved air floatation for the mixed (low strength and pretreated effluent of the high strength). Quantities of oil recovered by the process can compensate for the operational cost.
