摘　　要：本文介绍了屠宰废水水质特点、废水处理主要工艺、主要构筑物参数。针对废水有机污染物、氨氮、总氮、总磷、悬浮物等污染物含量高的特点,选用气浮+MABR+一级A/O+二级A/O+化学除磷工艺。实际运行表明,出水远优于《肉类加工工业书污染排放标准》(GB13457-92)间接排放标准。The paper introduces the characteristics of slaughtering wastewater,the main process of wastewater treatment and the main structure parameters.In view of the high content of organic pollutants,ammonia nitrogen,total nitrogen,total phosphorus,suspended matter and other pollutants in wastewater,air flotation+MABR+primary A/O+secondary A/O+chemical phosphorus removal process is selected.Actual operation shows that the effluent quality far exceeds the indirect discharge standards of the"Pollutant Discharge Standard for Meat Processing Industry"(GB13457-92).
