摘　　要：采用厌氧悬浮填料生物膜反应器工艺对费托合成废水进行处理,考察了高有机负荷条件下系统的运行情况。有机负荷小于31.1g/(L.d)时,COD去除率达97%以上;当有机负荷从39.7g/(L.d)增加至56.3g/(L.d)时,厌氧反应对COD的去除率从88%降至61%。实验结果表明,填料生物膜比悬浮污泥具有更高的活性,MBBR系统具有运行稳定、抗冲击力强的优点。The objective of this paper is to investigate COD removal efficiency of the Fischer-Tropsch-processing wastewater by applying the anaerobic moving-bed biofilm reactor（MBBR）.The contribution of the anaerobic MBBR to total COD removal efficiency reached 97% at an organic loading rate（OLR） of 31.1g/（L·d）.The COD removal efficiency of the anaerobic system had a slight decrease to 88% even though the feed OLR was increased to 39.7g/（L·d）,and gradually decreased to 61% when feed OLR was increased to 56.3g/（L·d）.The COD removal results in the anaerobic batch experiments of biofilm and sludge showed that the attached biofilm has higher activity than suspended sludge.The anaerobic MBBR system showed a characteristic of steady performance and resistance ability during the operation period.
