摘　　要：江西某油脂有限公司的生产废水和冲洗废水采用混凝气浮/UASB/生物接触氧化/混凝沉淀组合工艺处理.采用隔油+混凝气浮进行预处理,油脂去除率高且稳定;以UASB和生物接触氧化为主体工艺,污泥浓度高,处理效果好。稳定运行后,出水COD为89mg/L,BOD5为19mg/L,SS为69mg/L,动植物油为10mg/L,均达到《污水综合排放标准》(GB8978-1996)的一级标准。The integrated process of coagulation air floatation/UASB/biological contact oxidation/ coagulation sedimentation was adopted to treat the production and washing wastewater from an oil company in Jiangxi Province. The oil separator and coagulation air floatation were used in the pretreatment with a high and stable oil removal rate. The UASB and biological contact oxidation process were used as the main process with high sludge concentration and stable treatment effect. The effluent COD, BOD5, SS, oil and grease were 89 mg/L, 19 mg/L, 69 mg/L, and 10 nig/L, respectively, which coukl meet the requirement of first level in Integrated Wasteivater Discharge Standard( GB 8978-1996).
