厌氧氨氧化污泥亚硝酸盐中毒及活性恢复研究

Study on Nitrite Poisoning and Activity Recovery of Anammox Sludge

厌氧氨氧化反应在高氨氮污水处理方面具有重要的应用价值,此反应过程是自养型脱氮反应,无须额外补充碳源,可以大大降低污水处理厂的污水处理成本。厌氧氨氧化污泥培养受温度、pH、底物和金属离子等众多因素影响,对生存环境要求比较严格。本文以污水处理厂厌氧氨氧化污泥培养过程为研究对象,介绍了厌氧氨氧化污泥中毒现象的初步判断及污泥活性恢复的处理方法。

Anammox reaction has important application value in the treatment of wastewater with high ammonia nitrogen,this reaction process is an autotrophic denitrification reaction,and no additional carbon source is required,which can greatly reduce the sewage treatment cost of the sewage treatment plant.The cultivation of anammox sludge is affected by many factors such as temperature,pH,substrate and metal ions,and has strict requirements on the living environment.This paper takes the anammox sludge culture process of sewage treatment plant as the research object,introduces the preliminary judgment of anammox sludge poisoning and the treatment method of sludge activity recovery.
