The innovative and recently discovered n-damo process, based on anaerobic methane oxidation with nitrite, was developed in a membrane-based bioreactor and evaluated in terms of organic micropollutants (OMPs) removal. The main singularity of this study consisted in the evaluation of organic micropollutants (OMPs) removal in the biological reactor. A strategy consisting on progressively increasing the nitrogen loading rate in order to increase the specific denitrification activity was followed to check if the selected OMPs were co-metabolically biotransformed. Significant nitrite removal rate (24.1 mg N L⁻¹ d⁻¹) was achieved after only 30 days of operation. A maximum specific removal of 186.3 mg N gVSS⁻¹ d⁻¹ was obtained at the end of the operation, which is one of the highest previously reported. A successfully n-damo bacteria enrichment was achieved, being Candidatus Methylomirabilis the predominant bacteria during the whole operation attaining a maximum relative abundance of about 40 %. The natural hormones (E1 and E2) were completely removed in the bioreactor. The specific removal rates of erythromycin (ERY), fluoxetine (FLX), roxithromycin (ROX) and sulfamethoxazole (SMX) were successfully correlated with the specific nitrite removal rates, suggesting a co-metabolic biotransformation.

基于膜的生物反应器开发了基于亚硝酸盐的厌氧甲烷氧化的创新型和最近发现的n-damo工艺，并根据有机微污染物（OMP）的去除进行了评估。这项研究的主要奇点在于评估生物反应器中有机微量污染物（OMPs）的去除。遵循以逐渐增加氮负载速率以增加比反硝化活性为基础的策略，以检查所选择的OMP是否被共代谢生物转化。仅仅运行30天，亚硝酸盐去除率就达到了24.1 mg NL ^-1 d ^-1。最大比清除量为186.3 mg N gVSS ^-1 d ^-1是在操作结束时获得的，这是先前报告的最高记录之一。甲成功正DAMO细菌富集达到了，作为暂定整个操作达到约40％的最大相对丰度期间Methylomirabilis的优势菌。天然激素（E1和E2）在生物反应器中被完全去除。红霉素（ERY），氟西汀（FLX），罗红霉素（ROX）和磺胺甲恶唑（SMX）的比去除率已成功地与比亚硝酸盐去除率相关联，表明存在共代谢生物转化。
