摘　　要：利用多段多级A/O工艺对设计规模为3 500 m^3/d的禽类屠宰废水处理站进行提标改造。竣工验收监测结果表明,改造后的设施出水水质满足《肉类加工工业水污染物排放标准》(GB 13457—92)的一级排放标准,对COD、NH+4-N和动植物油的去除率分别达到97.6%、94.1%和93.8%,体现了多段多级A/O工艺的高效脱氮性能。同时,多段多级A/O工艺能显著节省基建投资并降低运行成本。The multiple segment and multi-stage A/O process [ （A/O）n ] was used to upgrade and reconstruct a poultry slaughter wastewater treatment station with design capacity as 3 500 m^3/d. The monitoring results of the acceptance check showed that the final effluent of modified project could meet the first standard specified in Discharge Standard of Water Pollutants for Meat Packing Industry （ GB 13457 -92）. The removal efficiency of COD, NH4^＋-N, animal and vegetable oil were up to 97.6%, 94.1% and 93.8% respectively. These results demonstrated that （A./O）n process had good performance on nitrogen removal. Meanwhile, the capital construction engineering investment and the operation cost could be saved to a great deal in the （A/O） n process. This case could be used as reference for the wastewater treatment engineering of slaughter house.
