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90mg?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。
英文摘要:
      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 treatment plant 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 90mg?L-1 ; in the third stage, the UASB reactor and the laboratory existing short-range nitrification reactors are coupled, the total nitrogen removal rate decreased 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.
