摘　　要：厌氧氨氧化是一种具有无需外加有机碳源、污泥产量低、脱氮效率高、温室气体排放少等优点的新型生物脱氮工艺,所以在低氧条件下通过反硝化氨氧化活性污泥系统处理污水具有良好应用前景。实验通过对传统A2O工艺和低氧条件下反硝化氨氧化污泥系统工艺的进出水COD、TN及TP的浓度进行测定,研究发现相比传统A2O工艺,改造后的反硝化氨氧化污泥系统工艺有更高的运行价值,能减少50%曝气能耗、80%有机物需求,且能提升污水处理厂脱氮效能、形成一套合理高效工艺,为污水处理厂节能降耗、高效脱氮设计方案提供科学依据。Anaerobic ammonia oxidation(ANAMMOX)is a new biological denitrification process with the advantages of no additional organic carbon source,low sludge production,high nitrogen removal efficiency,and low greenhouse gas emissions.Therefore,it has a good application prospect to treat sewage through the denitrification ammonia oxidation activated sludge system under low oxygen conditions.This experiment measured the concentration of COD,TN and TP in the influent water of the traditional A2O process and the denitrification ammonia oxidation sludge system under low oxygen conditions.The study found that compared with the traditional A2O process,the modified denitrifying ammonia oxidation sludge system process has higher operation value,can reduce 50%of the aeration energy consumption and 80%of the organic matter demand,and can improve the nitrogen removal efficiency of the sewage treatment plant,form a reasonable and efficient process,which provides a scientific basis for the energy saving and consumption reducing and efficient nitrogen removal design scheme of the sewage treatment plant.
