Abstract
Experiments are being conducted on the aerobic treatment of pig slurry and its subsequent anaerobic storage intended to determine lower cost methods of odour control. One series, using batch aeration for 3 to 9 days followed by storage for one year, has been completed. This paper describes a model of the storage phase. A model of bacterial growth based on Monod kinetics is used. Two forms of inhibition are included to improve the agreement with the experimental data. The model successfully describes many features found in the experiments, though others, such as the very rapid changes in volatile fatty and concentrations observed in some of the experiments, do not appear. The available literature on the modelling and microbiology of waste treatment offers no satisfactory explanations of these observations. At present the model can be applied only to the situations considered here, but it could provide the basis for further development.
