Partial nitritation-anammox was carried out successfully in a continuous fed Sequencing Batch Reactor (cf-SBR), composed of 3 compartments operated in continuous mode. The reactor was operated with floccular biomass (flocs) and biofilm to remove nitrogen from the anaerobic effluent from the potato industry at different nitrogen loading rates (0.16 g TN L⁻¹ d⁻¹ - 0.8 g TN L⁻¹ d⁻¹). At the maximum nitrogen loading rate (NLR) evaluated the nitrogen removal and ammonia oxidation achieved were 62% and 74% respectively. During the evaluation of the NLR, it was observed an improvement of the characteristics of the sludge, improving the Sludge Volumetric Index (SVI) from 228 to 63 mL g⁻¹ MLSS. Moreover, molecular analysis (qPCR) confirmed the presence of anammox bacteria on the flocs and in the biofilm from the cf-SBR. The results showed the capability of the reactor to carry out the partial nitritation-anammox in the same reactor at pilot scale. The cf-SBR was presented as a suitable and feasible technology for advanced nitrogen removal under partial nitritation and anammox conditions.

在连续进料的分批间歇式反应器（cf-SBR）中成功进行了部分亚硝化氨氧化反应，该反应器由以连续模式运行的3个隔室组成。该反应器以絮凝的生物质（絮凝物）和生物膜运行，以不同的氮负荷率（0.16 g TN L ^-1 d ^-1 -0.8 g TN L ^-1 d ^-1）从马铃薯工业的厌氧废水中去除氮。在评估的最大氮负荷率（NLR）下，脱氮和氨氧化分别达到62％和74％。在NLR评估过程中，观察到污泥特性得到改善，污泥体积指数（SVI）从228提高到63 mL g ^-1MLSS。此外，分子分析（qPCR）证实了cf-SBR的絮凝物和生物膜中存在厌氧氨氧化细菌。结果表明，该反应器具有在同一反应器中以中试规模进行部分硝化-厌氧氨氧化反应的能力。cf-SBR被认为是在部分硝化和厌氧条件下进行高级脱氮的合适可行技术。
