| Abstract: | Currently the accepted practice for swine wastewater disposal is land application after stabilisation in a lagoon. This disposal method can exacerbate odour emissions, contributes to soil contamination and eutrophication of waterways. Intensification of the pig industry has increased the impact of individual piggeries; this combined with tightening legislation is causing the pig industry in Australia to look at alternative treatment methods.
A pilot scale sequencing batch reactor (SBR) was built to treat piggery wastewater and achieved NH4+ and odour reductions of greater than 99% as well as 80% removal of COD and as high as a 60% reduction of PO43-. The optimization problem of anaerobic and aerobic cycle times of a sequencing batch reactor (SBR) for biological carbon and phosphorus removal was examined using a dynamic mathematical model. The model showed that there exists an optimum combination of anaerobic and aerobic cycle times for a SBR treating municipal and industrial wastewater. |
