摘　　要：采用DAF+MBBR工艺处理某食品加工厂经预处理的CIP废水及模具清洗废水。运行结果表明,MBBR悬浮填料为45%、水力停留时间为54 h、污泥龄为10 d时,该系统反应稳定,COD及SS去除率均达90%以上,保证出水水质达《污水排入城镇下水道水质标准》(DB 31/445—2009)中规定排放标准,是工厂用地有限情况下理想的工艺选择。DAF ＋ MBBR process was adopted as treatment process on a food processing plant,and raw water was pre-treated CIP waste water and mold washing waste water.Results indicate that when suspended packing is 45%,HRT is 54 h,sludge age is 10 days of MBBR process,the system operated stability.COD and SS removal rate reach more than 90%,which can ensure effluent quality reach the Discharge Standard For Municipal Sewerage（DB 31/445-2009） in the condition of limited footprint.
