摘　　要：采用混凝沉淀/兼氧/CASS工艺处理抗生素生产废水,经过6个多月的试运行,出水水质稳定达标,混凝沉淀、兼氧、CASS处理单元对COD的平均去除率分别大于47%、61%、92%,吨水投资为5 500元,运行费用为1.75元/m3。工程验收监测结果表明,系统出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准,COD去除率为97.8%,SS去除率为97.1%,氨氮去除率为99.6%。The combined process of coagulation sedimentation, facuhative anaerobic treatment and cyclic activated sludge system （CASS） was used to treat antibiotics wastewater. After the commissioning for more than 6 months, the effluent quality is stable and reaches the standard. The removal rates of COD by different treatment units are more than 47%, 61% and 92% respectively. The investment index of one ton is 5 500 yuan and the operation cost is 1.75 yuan/m^3. The acceptance results show that the effluent quality meets the first class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）. The removal rates of COD, SS and NH3 -N are 97.8%, 97.1% and 99.6% respectively.
