Sanitary landfilling of municipal solid wastes (MSW) combined with incinerated residuals is a disposal method specific to Taiwan. The purpose of this study was to explore the influences that adsorption, desorption, and biological reactions in landfilling may have on the quality of leachate. Not only did different combinations and the stratification of waste have to be considered, but anaerobic and semiaerobic landfilling have also been simulated. COD concentrations of leachate were processed by using a numerical method to get a simulation model for the estimation of variations in the organic pollutants in the leachate. The intensities of leachate from both semiaerobic and anaerobic landfilling, were also explored with this model. Comparing the simulation with the experimental data, we found that the degradation of the leachate quality was approximately similar for both type of data.
