摘　　要：从反应器脱氮性能和好氧颗粒污泥理化性状方面研究了pH值对好氧颗粒污泥同步硝化反硝化脱氮过程的影响.结果表明,好氧颗粒污泥微生态环境的形成,大大增强其耐酸碱冲击负荷能力,在pH值8～9范围内氨氮去除率均达到95%以上.在pH值6～9范围内,好氧颗粒污泥理化性状稳定,没有发生解体现象.The influence of pH value on simultaneous nitrification and denitrification （SND） process of aerobic granule sludge was studied in the respect of reaction denitrifying and aerobic granule sludge physiochemical properties. The formation of aerobic granules sludge microbioenvironment strengthened greatly its resisting acid and basic lashing load capacity; at pH value of 8-9 the NH4^＋-N removal rate all reached above 95%; at pH value of 6-9, the aerobic granule sludge physicochemical property was stable, without happening disintegration phenomenon.
