| 摘 要： | 引 言短程生物脱氮的概念就是将废水中的氨氮氧化为亚硝酸盐 ,采用适当的手段阻止其进一步氧化为硝酸盐 ,然后直接进入反硝化阶段 .这样 ,将节省2 5 %因为供氧而消耗的能源 ,在反硝化过程中将节省 4 0 %的有机碳源 ,同时反应的速率大幅度提高 ,剩余污泥量大为减少1～ 5] .实现短程硝化与反硝化的关键在于抑制硝酸菌的增长 ,从而导致亚硝酸盐在硝化过程中得到稳定的积累6] .短程生物脱氮工艺尤其适用于低碳氮比、高氨氮、高pH值和高碱度废水的处理 ,而在处理过程中较多地采用序批式生 物反应器 (SBR) .序批式间歇活性污泥法的整个处理…

| Abstract: | In this study, laboratory-scale experiments were conducted by using Sequencing Batch Reactor (SBR) activated sludge process to treat wastewater stream from a pharmaceutical factory. Biological nitrogen removal can be achieved via partial nitrification and denitrification and its efficiency was above 99% at 23℃±1℃. The experimental results indicated that the nitrite oxidizers were more sensitive than ammonia oxidizers to the free ammonia in wastewater. The ammonia was oxidized at pH 7 and 7.5 respectively, which suggested a critical free ammonia concentration of 0.2mg*L-1 at which the nitrite oxidizers were inhibited. |
