摘要: 采用A/O-CSTR工艺处理高氨氮污泥脱水液。进水氨氮浓度浓度约为375 mg/L，C/N比小于1.0，反硝化碳源明显不足。A/O反应器完成短程硝化反应，CSTR定期投加初沉污泥作为碳源进行反硝化。两者联合达到总氮去除的目的。实验研究短程硝化反应的启动过程，以及CSTR出水回流对短程硝化和系统脱氮效果的影响。实验结果表明系统具有良好的硝化反硝化效果。A/O反应器亚硝酸盐积累率迅速提高并稳定在90%以上。CSTR有效利用初沉污泥实现了稳定的反硝化。出水回流有利于提高总氮去除率，在回流比为200%时，系统平均总氮去除率达到85%以上。

Abstract: High strength ammonia sludge dewatering water was treated by a A/O-CSTR process. The ammonia content was about 350 mg/L. The carbon source for denitrification was deficient due to the ratio of C/N was below 1.0. Ammonia of reject water was nitrified in A/O reactor and then reduced to nitrogen gas by denitrifiers in CSTR， with using primary sludge as additional carbon source. The start-up of partial nitrification was investigated. The effects of the effluent recycle on partial nitrification and nitrogen removal efficiency were also studied. The results shows that the system has a good performance in total nitrogen removal. The nitrite accumulate ratio was improved and maintained above 90%. The primary sludge were successful utilized as the carbon source for stable denitrification. The recycle of CSTR effluent benefited nitrogen removal efficiency. As the recycle ratio was 200%， total nitrogen removal efficiency was more than 85%.
