The present study aimed to optimize the removal efficiency of ammonia nitrogen (NH₃‐N) and total kjeldhal nitrogen (TKN) from domestic wastewater as a function of hydraulic loading rates (HLRs) (0.16–5.44 m³ m^–3 day^–1) and the aeration rate (3, 5 and 10 L min^–1) in a vertical flow aerated steel slag filter (VFASSF) system with nitrifier bacteria. The nitrifier bacterial cell morphology was determined using scanning electron microscopy (SEM) analysis.

利用硝化细菌优化垂直流曝气钢渣过滤系统以去除生活污水中的养分

本研究旨在优化作为水力负荷率（HLR）（0.16-5.44 m ³ m ^–3天^{–1 –1}的函数）的生活污水中氨氮（NH ₃ ‐N）和总凯氏氮（TKN）的去除效率。）和带有硝化细菌的立式曝气钢渣过滤器（VFASSF）系统中的曝气速率（3、5和10 L min ^–1）。使用扫描电子显微镜（SEM）分析确定硝化细菌的细胞形态。
