| 摘 要： | 采用厌氧折流板反应器(Anaerobic baffled reactor, ABR)工艺处理模拟养猪场废水,考察低温(15±1)℃、中温(35±1)℃、高温(50±1)℃等3个温度条件对ABR处理效果和微生物群落结构的影响.同时,在水力停留时间HRT为24 h,进水COD为2000 mg·L-1的条件下,考察了不同温度条件对ABR系统出水COD、pH、挥发性脂肪酸(Volatile fatty acid, VFA)的影响.最后,采用扫描电镜和荧光原位杂交技术(Fluorescence in situ hybridization, FISH)分别考察了不同温度条件对污泥微生物形态、种群结构和相对丰度的影响.结果显示,中温条件下系统的COD去除率最高,保持在96%以上,而低温和高温条件下系统的COD去除率均在70%左右;温度变化对反应器内pH值的影响不大;VFA含量在中温条件下最低,表示反应器运行最稳定;FISH结果显示,中温条件下系统真细菌和古细菌的总相对丰度最高,比低温和高温条件下分别高出12%和27%. |
