在土壤含水层处理（SAT）过程中，许多地方都观察到了氮的去除 氮主要作为氨氮添加到土壤中的地点。普通的 SAT的脱氮假设为两步脱氮过程 自养硝化和异养反硝化。然而，很少有人参加 系统的生物需氧量（BOD）与氮（N）的比率可以 维持异养反硝化。大多数系统条件都会导致 异养氮的最大去除效率约为30%，而 在SAT系统中观察到较高的脱氮效率。这 这意味着其他一些机制要对额外的 脱氮。因此，提出了一种可持续的反硝化机制 在SAT系统中是厌氧氨氧化（Anammox）。本文报道了 用于评估厌氧氨存在的批量试验结果 SAT土壤中的氧化。这些批量实验比较了产气量和产气量 异养厌氧氨氧化试验的氨氮和硝酸盐去除率 脱氮试验和空白。产气结果表明: 在厌氧氨氧化试验装置中发生自养反硝化。典型的 异养反硝化会产生CO2和N2气体。 在厌氧氨氧化试验装置中观察到的氮气生成量与 二氧化碳气体生产。这表明，其他一些机制是造成这种现象的原因 观察到反硝化作用。这项初步实验确定了 并提供了一种基本的测试方法，可用于 SAT期间对厌氧氨氧化过程的未来研究包括16篇参考文献、表格和图表。

Nitrogen removal has been observed during soil aquifer treatment (SAT) at many sites where nitrogen is primarily added to the soil as ammonia-nitrogen. A common hypothesis for this nitrogen removal in SAT is the two-step process of autotrophic nitrification and heterotrophic denitrification. However, few SAT systems have the biological oxygen demand (BOD) to nitrogen (N) ratios that can sustain heterotrophic denitrification. Most system conditions would result in maximum heterotrophic nitrogen removal efficiencies of about 30%, whereas, much higher nitrogen removal efficiencies have been observed in SAT systems. This would suggest that some other mechanisms are responsible for the additional nitrogen removal. Therefore, a proposed sustainable mechanism for denitrification in SAT systems is anaerobic ammonium oxidation (Anammox). This paper reports the results of batch tests used to assess the presence of anaerobic ammonium oxidation in an SAT soil. These batch experiments compared the gas production and ammonia and nitrate removal rates of the Anammox tests to heterotrophic denitrification tests and blanks. The gas production results demonstrated that autotrophic denitrification occurred in the Anammox test set. Typical heterotrophic denitrification would result in the production of CO2 and N2 gases. The observed N2 gas production in the Anammox test set did not correlate with the CO2 gas production. This suggests that some other mechanism is responsible for the denitrification observed. This preliminary experiment has identified the presence of microbes and provides a basic testing method that can be employed in future studies of the Anammox process during SAT.
