结合工程实例，介绍了气浮-A／O／SBR工艺在处理冷食加工废水处理工程中的实际应用。运行结果表明：该工艺运行稳定，处理效果好，COD去除率在90％以上，各项指标均优于GB8978--1996《污水综合排放标准》三级排放标准。“,”Based on project examples,it is introduced the actual use of air floatation-A/O/SBR technology in treating cool food processing wastewater. The running result shows that the process runs well with good treatment effect and the removal rate of COD can reach more than 90%. Every index can meet the third-order of ＂ Integrated Wastewater Discharge Standard＂ （ GB 8978--1996）
