Resumo: |
This work studied the anaerobic horizontal reactor of fixed bed (RAHLF)for treatment of waste waters, developed in the Department of Hydraulics and Sanitation of the School of Engineering of São Carlos USP by investigating some mathematical models with two different RAHLFs conditions in different scales: the first in pilot scale by treating domestic and other in bench scale by treating synthetic substratum. The pseudo-homogeneous and heterogeneous models were investigated by considering or not the substratum dispersion in the axial direction. The models were resolved numerically by fourth order Runge-Kutta method, orthogonal collocation and finite differences. The values were compared to reactor experimental values. In the pseudo-homogeneous resolution model with dispersion by using the reactor data in pilot scale was adjusted the axial dispersion coefficient to 1,65.10-3 m2.s-1, after that was used in the solution of the heterogeneous model. The benches reactor values were used to obtain the dispersion coefficient as Zero. The parameter kinetic variation in the reactor was investigated by verifying that this variation is not responsible for the difference between the experimental data and those previewed by the model. |
