摘要
采用微电解+厌氧折流板反应器(ABR)+上流式厌氧污泥床(UASB)+膜生物反应器(MBR)组合工艺对纤维乙醇滤液进行处理。结果表明,当滤液COD在12000mg·L-1左右,该组合工艺中厌氧停留时间(HRT)为48h时,厌氧COD去除率达到72%,MBR停留时间(HRT)20h时,COD的去除率在80.8%～87.5%之间,出水COD浓度稳定在301～537mg·L-1,且MBR抗冲击负荷能力较强。
Wastewater from the production of cellulosic ethanol was treated by the processes of internal electrolysis method ＋ABR＋UASB ＋MBR. The results of running indicated that,when COD is 12 000 mg-L^-1 and HRT of UASB is 48 h,the COD removal rate reaches 72% and HRT of MBR is 20 h, the COD removal rate reaches 80.8%-87.5%. The COD in effluent is 301 -537 mg. L^-1 and MBR has better resistance to impact load.
