摘要(Abstract)：

本文系统地评价了缺氧时间/好氧时间变化对处理海水养殖废水的序批式生物膜反应器(SBBR)中胞外聚合物(EPS)特性的影响。研究结果表明,在SBBR运行过程中好氧时间的缩短能抑制生物膜中微生物分泌EPS,从而导致松散附着EPS(LB-EPS)和紧密附着EPS(TB-EPS)中蛋白质(PN)和多糖(PS)含量随着好氧时间的缩短而降低。随着缺氧时间/好氧时间的变化,LB-EPS和TB-EPS的三维荧光(3D-EEM)光谱中代表不同化学组分的荧光峰位置发生了移动,荧光峰强度也发生了变化,部分荧光峰在缺氧时间/好氧时间为9.5h/0.5h和8h/1h时消失。LB-EPS和TB-EPS的傅里叶红外(FTIR)光谱中不同吸收峰的强度随着缺氧时间/好氧时间变化而变化,好氧时间的缩短对生物膜中LB-EPS和TBEPS的PN和PS中官能团有明显的影响。
