摘　　要：隆力奇生物科技股份有限公司采用UASB/延时曝气/气浮联合工艺处理高浓度日用化工废水,进水COD为20 000 mg/L,出水COD<100 mg/L,进水SS为2 000 mg/L,出水SS<70mg/L,进水LAS为100 mg/L,出水LAS<5 mg/L,出水水质优于《污水综合排放标准》(GB 8978—1996)的一级标准。介绍了废水水质、水量、工艺流程、设计参数以及实际运行效果,可供类似工程借鉴。The wastewater treatment project of Longliqi Bioscience Co. Ltd. adopts UASB/extend- ed aeration/air floatation process to treat high concentration commodity chemical wastewater. COD, SS and LAS were reduced from 20 000 mg/L, 2 000 mg/L and 100 mg/L in the influent to 〈 100 mg/L, 〈 70 mg/L and 〈 5 mg/L in the effluent respectively. The effluent quality was better than the first class criteria specified in the Integrated Wastewater Discharge Standard （ GB 8978 - 1996 ）. The wastewater quantity and quality, treatment process, design parameters of main structures and operation efficiency of the wastewater treatment project were introduced for reference.
