厌氧氨氧化颗粒污泥的快速形成
Faster formation of anammox granular sludge
摘要
Abstract
Anammox granular sludge was formed in an anoxic EGSB reactor, which was started up with the mixture of aerobic granular sludge and anammox biofilm. The reactor was operated under the regulation of key controlling factors, including substrate concentration and upflow velocity according to sludge properties and operating results. In this way, anammox granular sludge was formed faster. N removal efficiency, particle size distribution, granular surface morphology, internal structure and distribution of microorganisms were also determined. Mean granular size reached 0.556 mm after 80 d. NRR was 4.758 kg N·m-3·d-1 after 89 d. FISH analysis showed that anammox bacteria dominated the granular sludge. SEM and TEM showed that the granular sludge contained multiple gathered smaller granules with irregular shape and closely arranged internal structure.关键词
