通过不同污泥含量的接种实现了旺盛的厌氧氨氧化（anammox）活性。从使用了 2 年的产甲烷反应器中取出的含有高有机物和甲醇含量的颗粒用作接种物，以在 1.1 L 上流式厌氧污泥床反应器中富集厌氧氨氧化生物量。运行83 d后出现厌氧氨氧化活性，通过厌氧氨氧化污泥的高效粒化，最终脱氮率为11.7 kg N m(-3) d(-1)。基于16S rDNA测序的分析证实Candidatus“Brocadia”是富集生物量中的优势种群。 (C) 2010 Elsevier Ltd. 保留所有权利。
Vigorous anaerobic ammonium oxidation (anammox) activity was realized by seeding with diverse sludge contents. Granules taken from a 2-year old methanogenic reactor loaded with high organic and methanol contents were used as inoculum to enrich anammox biomass in a 1.1 L upflow anaerobic sludge blanket reactor. Anammox activity appeared after an operation of 83 d resulting in the final nitrogen removal rate of 11.7 kg N m(-3) d(-1) with the efficient granulation of anammox sludge. The analysis based on 16S rDNA sequencing confirmed that Candidatus "Brocadia" was the dominant population in the enriched biomass. (C) 2010 Elsevier Ltd. All rights reserved.
