Nitrification Characteristics of the Suspended and AttachedMicroorganisms in Hybrid Biological Reactor
复合生物反应器中两相微生物硝化特性比较

Artificial ammonia wastewater was treated with a batch hybrid biological reactor, concentration of influent NH3N being about 160 mg/L, HRT being 12h, SRT being 10d, NV may reach 015g/(gd).The emphasis was put on comparison between nitrification characteristics of the suspended microorganism and that of the attached microorganisms in the reactor. The results reviewed that the attached microorganism showed a little lower nitrification activity than the suspended microorganism, with specific degradation rate of NH3N was respectively 053 and 068 g/(gd),but higher ability of resistance to inhibition of toxic organic compounds for the attached microorganism was found, while phenol, quinoline or pydine existed.
