摘要
在讨论生物膜反硝化原理的基础上研究了移动床生物膜反应器(MBBR)的生物反硝化特性。在NO3--N负荷为0.32kg/(m3.d)条件下,MBBR系统达稳态时的平均生物膜量为33.7mg/g,生物膜厚为100μm左右;生物膜的COD降解速率为166.5mg/(g.h),硝氮降解速率为32.1mg/(g.h)。
The characteristics of biological denitrification of a moving bed biofllm reactor（MBBR） is studied based on the discussion.on the denitrification principle of biofilm. Under the condition of load with 0.32 kg/（ m^3·d）, the average attached biomass is 3.77 mg/g and the thickness of biofilm is about 100μm; COD degradation rate is 166.5 mg/（g·h） and nitrate degradation rate is 32.1 mg/（ g·h）.
