摘　　要：考察了序批式(SBR)活性污泥工艺运行方式对其脱氮规律的影响。结果表明:SBR工艺采用进水加水下搅拌-曝气反应-搅拌-沉淀-出水-闲置的强化脱氮运行工序对城市污水的氨氮、总氮去除均较为理想,氨氮和总氮平均去除率均可达95%以上,另外该工序对污水中氮质量浓度的冲击负荷抵抗能力较强,进水总氮从7.63 mg·L^-1增至76.45 mg·L^-1时,其出水总氮仍可保持在1.5 mg·L^-1以下,去除率可稳定在95%左右。The influence of sequence batch(SBR)activated sludge process operation mode on its denitrification effect was investigated.The results showed that,SBR denitrification strengthen process sequence of inlet under stirring(no aeration),aeration,stirring(no aeration),precipitation,outlet and idle stage had better performance on ammonia nitrogen(N-NH3)and total nitrogen(TN)removal.The average removal rate of N-NH3 and TN both were more than 95%.It also had outstanding resistance of nitrogen impact loading.When TN increased from 7.63 mg·L^-1 to 76.45 mg·L^-1,the TN of outlet was than 1.5 mg·L^-1,the removal efficiency was steady at around 95%.
