摘要：

A hybrid upflow sludge bed-filter (UBF) anaerobic reactor was successfully used for treatment of synthetic soluble 1% sugar waste. An hysteresis phenomenon was observed and discussed with respect to changes in acidogenic/acetoclastic specific activities ratio. The Haldane equation was adapted for predicting performance inhibition by undissociated acids as a function of substrate-COD and pH. The Monod and adapted Haldane models were solved simultaneously with substrate mass balance for a UBF reactor. The soluble COD removal efficiency and methane productivity were predicted as a function of the dilution rate. Critical values of solid and hydraulic residence times were also estimated and discussed in detail.
