摘　　要：北京某市政污水厂采用基于氨氮的曝气控制策略,设定好氧池末端氨氮在1.0~2.5mg/L之间。在不加碳源、超设计水量负荷的情况下,好氧池末端氨氮日均值实际控制在0.15~2.78mg/L之间,总出水氨氮日均值最高为0.46mg/L。进水TN平均为51.0mg/L,出水TN平均值达到8.37mg/L,缺氧池出现反硝化吸磷反应,实现了高效脱氮除磷和低能耗运行。A municipal sewage plant in Beijing tried to adopt an aeration control strategy based on ammonia nitrogen, which set the ammonia nitrogen at the end of the aerobic tank to be between 1.0~2.5mg/L. Under the conditions of without carbon source dosing and exceeding the design water load, the actual daily average value of ammonia nitrogen at the end of the aerobic tank is controlled between 0.15~2.78mg/L, and the highest daily average value of total effluent ammonia nitrogen is 0.46mg/L. The average TN of influent is 51.0mg/L, the average TN of the effluent reached 8.37mg/L. At the same time, simultaneous denitrifying phosphorus accumulation occurred in the anoxic tank, realizing high-efficiency nitrogen and phosphorus removal and low energy consumption operation.
