The treatment performance of anaerobic ammonia oxidation (anammox) immobilized filler on different proportions of domestic wastewater was evaluated. The results showed that, in comparison to synthetic wastewater, 50% domestic wastewater promoted the anammox reaction of immobilized filler, while 100% domestic wastewater had no significant effect on the anammox activity of immobilized filler but the total nitrogen removal efficiency (TNRE) was improved through enhanced denitrification. The TNRE of the immobilized filler was 82.5%, which was significantly higher than that of AnGS (69.7%), and its average anammox contribution rate was more than 90%. This was because the encapsulated anammox biomass could better maintain competitive advantages and coordinate the symbiotic relationship with denitrifying bacteria. Moreover, lower NH-N concentration resulted in greater influence of C/N ratio on anammox performance than COD concentration, while the opposite was true at high NH-N concentration. This study verified that anammox immobilized filler is effective for mainstream applications.
考察了厌氧氨氧化（Anammox）固定填料在不同比例生活污水中的处理性能。结果表明，与合成废水相比，50%的生活污水促进了固定填料的 Anammox 反应，而 100%的生活污水对固定填料的 Anammox 活性没有显著影响，但通过增强反硝化作用提高了总氮去除效率（TNRE）。固定填料的 TNRE 为 82.5%，明显高于 AnGS（69.7%），其平均 Anammox 贡献率超过 90%。这是因为包埋的 Anammox 生物量可以更好地保持竞争优势，并与反硝化细菌协调共生关系。此外，较低的 NH-N 浓度使得 C/N 比对 Anammox 性能的影响大于 COD 浓度，而在高 NH-N 浓度下则相反。本研究验证了 Anammox 固定填料在主流应用中是有效的。
