| 中文摘要: |
| 传统生物脱氮处理需要大量的外加碳源和能源，厌氧氨氧化可节约脱氮成本。实验选用合肥经开区某污水处理厂的氧化沟污泥作为接种污泥，在上流式厌氧污泥床反应器（UASB）内进行反应。实验分为三个阶段：第一阶段为厌氧氨氧化菌培养阶段，75 天后氨氮去除率达到了 90.6%，亚硝态氮去除率达到了 91.3%，总氮去除率达到了 81.3%，启动成功；第二阶段在进水中加入不同浓度的有机碳源，此阶段进水 COD 浓度为90 mg·L-1 时总氮去除率最高，达到了 86.7%；第三阶段，将 UASB 反应器和实验室已有的短程硝化反应器耦合，总氮去除率略微下降但仍能达到 78.1%。除测量水质常规指标外，还使用平行因子法分析出水水样中的荧光物质。 |

| Traditional biological denitrification treatment requires a large amount of additional carbon sources and energy sources.Anaerobic ammonia oxidation can save the cost of denitrification.In the experiment，the oxidation ditch sludge of a sewage treatmentplant in Hefei Economic Development Zone was used as inoculation sludge，and the reaction was carried out in an up-flow anaerobic sludge bed reactor（UASB）.The experiment is divided into three stages：in the first stage，the anaerobic ammonia-oxidizing bacteria culture stage lasted for 75 days，the ammonia nitrogen removal rate reached 90.6%，the nitrite nitrogen removal rate reached 91.3%，and the total nitrogen removal rate reached 81.3%；in the second stage，different concentrations of organic carbon sources were added to the water，the total nitrogen removal rate reached 86.7% when the COD concentration of the influent was 90 mg·L-1；in the third stage，the UASB reactor and the laboratory existing short-range nitrification reactors are coupled，the total nitrogen removal ratedecreased slightly but still reached 78.1%.In addition to measuring routine water quality indicators，the parallel factor analysis method is also used to analyze fluorescent substances in water samples. |
