【摘要】 研究了水解酸化—好氧移动床生物膜反应器系统(HA-AMBBRs),对餐饮废水的处理性能。在水温12℃～30℃,进水 CODCr 浓度为500～4200mg/L,水解酸化阶段容积负荷2．43～19．3Kg COD/m3·d,好氧阶段容积负荷1．3～10．3Kg COD/m3·d,系统总水力停留时间9．0～12．5h 的操作条件下,出水 COD 可降到78．0～520．7mg/L,COD 去除率为83．0%～91．1%,油脂的去除率在98．9%以上。在 HA-AMBBRs 系统中投加光合细菌,能够提高处理效率,缩短水力停留时间。更多还原

【Abstract】 The Hydrolytic Acidification-Aerobic Moving Bed Biofilm Reactors(HA-AMBBRs) were used for the treatment of restaurant wastewater.With water temperature 12～30℃,influent COD 500～4200mg/L,volumetric organic loading(N_v)in hydrolytic acidification reactor (HA-MBBR)2.43～19.3KgCOD/m~3.d,N_v in aerobic reactor(AMBBR)1.3～10.3KgCOD/m~3·d, the total hydraulic retention time(HRT)of system 9.0～12.5h,the effluent COD was about 78.0～520.7mg/L and the COD removal efficiency was about 83.0%～91.1%.The removal effi- ciency of grease in restaurant wastewater was more than 98.9%.The HA-AMBBRs with bio-augmented by adding photosynthetic bacteria were of higher COD removal efficiency and less HRT。更多还原
