| Abstract |
Mathematical models have been developed to understand and optimize the biological wastewater treatment process. In this research, SSP(Simulation of Single sludge Process) program, based on IAWQ model NO.1, was used to evaluate treating capacity of a pertrochemical wastewater treatment plant. The biokinetic and stoichiometric coefficients were calibrated and verified, and then the treatment capacity was estimated. Sensitivity analysis showed that the effluent COD concentration was greatly influenced by the parameters such as μ_H, K_S, and K_(dH) and MLVSS was affected by Y_H and K_(dH), while other parameters hardly had any effect. The calculated kinetic and stoichiomertric coefficients were μ_H, 9day¹, k,_COD 80㎎/ℓ, K_d 0.133 and Y_H 0.515 gCOD/gCOD. However, verification resulted relative error of 30%∼40% which was maybe due to different operating condition in 1991 and 1992. As a result of estimating the treatment capacity, the maximum allowable volumatric loading rate would be 1.35㎏/㎥·day based on MLVSS of 8,000㎎/ℓ. This means that the treating capacity of 1992 can be incereased up to 24% |
