Biological contact oxidation (BCO) process and biological aerated filter (BAF) process were applied to decentralized wastewater treatment. The performances of two biofilm systems were monitored under four hydraulic loadings and six aeration rates. Effluent COD, NH4 +−N, SS concentrations were presented with respect to the hydraulic and organic loadings, as well as the effluent DO. If the water reuse criteria were to be achieved, a maximum hydraulic and organic loading of 12.0 m3/d and 2.0 kg COD/(m3┬Ěd), as well as a minimum effluent DO of 4.0 mg/L could be applied, respectively. Then kinetic analysis was carried out to describe the COD removal in two processes; for BAF there was: Se=S0 e-0.639t /(1+1.035t); and for BCO, Se=S0 [(1+0.947t) (1+1.242t)]. The correlation analysis showed that the two models could predict the effluent water quality based on the hydraulic retention time (HRT), so the appropriate hydraulic loading for certain effluent water quality could be determined. The two models could be applied to wastewater treatment practice.
