, 2017 沼气中的硫化氢是一种具有腐蚀性的有毒气体，因此在使用沼气前必须进行人工脱硫处理。化能自养型微生物在厌氧条件下，利用硝酸盐作为电子受体去除沼气中的H2S。本试验研究了以废水中的硝酸盐或亚硝酸作为电子受体，在不同沼气进气速率下沼气中H2S去除率及微生物结构解析，得出以下主要研究结果： （1）以硝酸盐模拟废水作为试验进水时，在接种污泥的反应器A、B和C中，沼气进气速率为0.5 L/min时，H2S去除率可达90%以上；在沼气进气速率为2 L/min、3 L/min和4 L/min时，H2S去除率在20%~35%

Isolation and Nitrate Reduction with Aerobic Denitrifiers
, 2013 氮氧化物是重要的环境污染物，排放到空气中会形成酸雨、诱发光化学烟雾、导致雾霾天气、破坏臭氧层等；以铵盐、硝酸盐或者亚硝酸盐形式排放到水中会引起水体富营养化、污染水质、破坏水源等。生物脱硝技术具有脱硝彻底、反应条件温和、投资少、设备简单、运行费用低等优点。近年来，好氧反硝化微生物因其能在有氧的条件下进行反硝化作用而成为研究热点。好氧反硝化微生物具有生长迅速、适应性强、脱硝速率高、具有同步硝化反硝化的潜力等优势。耐高盐或高碱等极端条件的好氧反硝化微生物，在烟气和含盐废水的脱硝中具有很大的应用价值 ...
