摘　　要：为提高传统生物脱氮工艺的脱氮水平,在分析传统生物脱氮工艺局限性的基础上提出了传统A/O工艺的改良工艺即A/O/N工艺。通过采取相同能耗条件下最佳工艺参数的对比试验研究,试验结果表明两工艺对CODCr去除效果均较好,A/O/N工艺对NH3-N和TN的去除效果明显优于A/O工艺,且耐NH3-N冲击负荷更强。For the purpose of improving the nitrogen removal efficiency,a modified A/O process： A/O/N process was proposed based on analyzing the defects of conventional biological nitrogen removal process.A comparative test between the said two processes with the same energy consumption under the optimal condition was carried out,the results showed that,the CODCr removal effects by the two processes were both good;however,A/O/N process had a significantly better effect on NH3-N and TN removal,and its resistance to NH3-N impact load was also higher.
