采用步进式进样方法,在步进进料比为35%:35:30%时,在营养物去除方面表现出良好的性能,相应的NH4-N^+、TN和PO4^3-P分别提高到最佳97.3%、81.8%和89.56%。在最佳投喂比下,在三个好氧区降低DO浓度为0.7~1.0mg/L,使整个营养盐转化为劣化状... 详细信息

采用步进式进样方法,在步进进料比为35%:35:30%时,在营养物去除方面表现出良好的性能,相应的NH4-N^+、TN和PO4^3-P分别提高到最佳97.3%、81.8%和89.56%。在最佳投喂比下,在三个好氧区降低DO浓度为0.7~1.0mg/L,使整个营养盐转化为劣化状态,从而刺激SND,缓解脱氮恶化,不利于除磷。在改变SND状态的基础上(在好氧区2使DO浓度恢复到2mg/L),在厌氧区增加分批进料的比例从35%:35%:30%增至45%:35%:20%,以提高除磷效果。结果表明,磷和TN的总去除率平均回收率分别为61.3%和66.8%,由于提高了低DO和少量碳源引起的丝状茵活性,SVI从异常状态恢复。
