Abstract: A novel Anaerobic Digestion Model No.1 based dispersive model was developed to simulate the upflow anaerobic sludge blanket reactor (UASB), in which both hydrodynamics and bio-dynamics were taken into account. The partial differential equations in the model was solved by finite difference method in Matlab. A tracer study and two loading-shock experiments were used to validate the reactors hydrodynamics and bio-dynamics, respectively. The simulated data match the experimental data very well. Besides, the developed model can reflect the reactors status at different heights, which makes it possible to give early warnings in abnormal situations.
Key words: upflow anaerobic sludge blanket reactor (UASB), hydrodynamics, bio-dynamics, anaerobic model No.1
