摘　　要：为了探讨剩余污泥减量问题,采用臭氧氧化法处理曝气池回流污泥,考察臭氧氧化污泥减量技术对出水COD、NH_3-N和TP的影响。实验结果表明：剩余污泥的比脱氢酶活性随通臭氧时间的延长而减少；在被臭氧氧化的泥水混合液中,SCOD的值是随时间的延长而增大；臭氧处理后的剩余污泥排入曝气池中,出水的COD、TP去除率无明显变化,出水NH_3-N去除率有所增加。To discuss the problem of excess sludge reduction, ozonation was used to treat sludge from aerotank, and influences to COD, NH3-N and TP by excess sludge reduction were studied. Test indicated that： specific desaturase activity of excess sludge decreased with oxidation time; in mixture of sludge and water after oxidation, SCOD increased with time extending; the removal rate of COD and TP had no obvious change,and the removal rate of NH3-N increased a little when access sludge after oxidation was discharged into Aerotank.
