This study introduced an innovative pathway utilizing an algal anaerobic ammonium oxidation (ALGAMMOX) system to treat ammonium wastewater. Lake bottom sludge and anammox sludge were used to cultivate functional microorganisms and microalgae for nitrogen removal in an upflow reactor made of transparent materials. The results showed that the ALGAMMOX system achieved 87.40 % nitrogen removal when the influent NH -N concentration was 100 mg-N/L. Further analysis showed that anammox bacteria (8.87 %) and nitrosobacteria (3.74 %) were crucial contributors, playing essential roles in nitrogen removal. The 16S rRNA gene showed that the anammox bacteria in the sludge transitioned from to . The 18S rRNA gene revealed that and were the dominant microalgae in the system at a relative abundance of 7.99 %, 3.64 % and 3.14 %, respectively. This novel approach provides a theoretical foundation for ammonium wastewater treatment.
本研究引入了一种创新途径，利用藻类厌氧氨氧化（ALGAMMOX）系统处理含铵废水。在由透明材料制成的上流式反应器中，利用湖底污泥和厌氧氨氧化污泥培养功能微生物和微藻以进行氮去除。结果表明，当进水NH₄⁺-N浓度为100 mg-N/L时，ALGAMMOX系统实现了87.40%的氮去除率。进一步分析表明，厌氧氨氧化菌（8.87%）和亚硝化菌（3.74%）是关键贡献者，在氮去除中发挥着重要作用。16S rRNA基因显示，污泥中的厌氧氨氧化菌从……转变为……。18S rRNA基因表明，……和……是系统中的优势微藻，相对丰度分别为7.99%、3.64%和3.14%。这种新方法为含铵废水处理提供了理论基础。 （注：原文中部分内容缺失，已根据格式尽量完整翻译）
