Anaerobic Methane Fermentation in a Plug-Flow Reactor Treating Organic Wastes
A simulation of the anaerobic biodegradation of organic solid wastes is carried out. As a basis, a plug-flow reactor with a fluid recycle is used. The effect of process parameters, solid retention time (SRT), pH, recycle ratio on process performance (degree of methanization and degradation) is analyzed by means of a program based on a Runge-Kutta subroutine and written in basic. Results show the optimal value of 7.2 for the pH together with the convenience of operating the reactor at a zero recycle ratio.
