概要:
An method to identify the wastewater composition from biological responses in activated sludge reactors. From the field experiment, the municipal wastewater constituents and concentrations were calculated to demonstrate the
…
back-calculation approach. The labor intensity of the analysis was also comparatively discussed to that of the conventional wastewater sampling/ analysis method Low-cost biological treatment like bio-filter/ trickling filter reactor can be modelled and optimized with a novel design. The process responses of a pilot-scale trickling filter reactor were investigated by changing the hydraulic loadings and analyzed in laboratory. The liquid hold-up in the reactor, which was thought to be correlated with the wetted surface area was especially focused on. A dynamic simulation was also performed to discuss influential kinetic parameters on the calculation.

概要:
Nitrification performances of moving-bed biofilm reactor were analysed and modelled by feeding surface water in Vietnam and synthetic water in laboratory respectively. The model was composed of the module to express physical

properties of the reactor and the module to show the mass transfer and biochemical reactions in a dynamic manner. The rate expressions for ammonia oxidizer, nitrite oxidizer and ordinary heterotrophs were adopted from literature whilst dominant kinetic parameters were experimentally calibrated.
