摘　　要：本试验在连续运行的条件下,考察了C/N对连续运行的复合生物反应系统有机物、氨氮去除效果的影响,结果表明,复合生物反应器在试验运行条件下,对COD,NH3-N的去除率都在90%以上,其中的生物膜对去除效果起主要作用。但C/N在30左右时,系统会发生污泥膨胀,且随着C/N的增加,污泥膨胀发生的更加频繁。The effects of C/N on removal efficiency of COD and NH3-N of hybrid biological reactor were discussed under continuous operation conditions. The results showed that the removal efficiency of COD and NH3-N were both more than 90 %. The biofilm plays a main role in removing the COD and NH3-N in hybrid biological reactor. But sludge bulking will occur when C/N is around 30 in the system. With the increase of the C/N, the sludge bulking will take place more frequently.
