Nitrification of Municipal Wastewater by Suspended Medium Bioreactor

Abstract:

The performance of Short-HRT suspended medium bioreactor was investigated to treat the municipal effluent from the chemical-biological flocculation plant. The results showed that under the condition of influent ammonia concentration 9.0-15.0 mg/L, carrier filling ratio 30%, optimal air/water ratio and optimal HRT were 2.0 h and 2.7 h, respectively. The removal efficiency of ammonia is 49.7% with ammonia volume load of 0.058 kg/m3•d. Molecular biological method analysis indicated that bacteria species were abundant and could adapt themselves to varied circumstance in the Short-HRT suspended medium bioreactor.
