摘　　要：分别以活性污泥和厌氧颗粒污泥培养的好氧颗粒污泥为对象,对成熟污泥颗粒的脱氮性能进行了比较研究。结果表明,颗粒污泥驯化成熟之后,对氨氮的去除效果维持在95%左右,与其污泥接种源没有明显的相关关系;对一个降解周期内氮的形态分析表明,在颗粒污泥存在的反应器内发生了同步硝化反硝化。This paper studied nitrification and denitrification of mature aerobic granular which cultivated from activated sludge and anaerobic granular sludge. The results indicated that, after aerobic granular sludge was matured, removal rate of ammonia nitrogen could maintain at 95 %; Different forms of ammonia nitrogen was analysed in one degradatic period, and the results showed nitrification and denitrification occurred simultaneously in the reactor filled with aerobic granular.
