摘要
采用 3套相似的小试UASB系统 ,分别接种普通厌氧颗粒污泥、普通厌氧颗粒污泥与好氧活性污泥的混合污泥以及河底污泥 ,以自配含NH+ 4 N和NO-2 N的废水为进水 ,分别经过 2 2 5d、2 2 0d和 2 5 0d的启动运行 ,均成功实现了厌氧氨氧化过程 ,氨氮去除率都达到 80 %以上 。
Seeded with normal anaerobic granular sludge,mixed sludge(normal anaerobic granular sludge and aerobic activate sludge),river sediments respectively, feeding with synthetic wastewater containing ammonia and nitrite, three similar lab-scale UASB systems were started up. After 225,220 and 250d s operation respectively, anaerobic ammonia oxidation processes were obtained successfully in three reactors, the NH + 4-N removal efficiencies were all above 80%. The ratios of NH + 4-N removed to NO - 2-N remove...
