【 摘 要 】

Swine production is considered an activity with a high environmental impact, due to the presence of a high number of contaminants in the effluents that come out from the piggery. In this study the feasibility of a combined process biodigestor and stabilization ponds (anaerobic, facultative and maturation) connected in sequence fed with sludge from a swine manure treatment unit was evaluated. The system showed itsetf as efficient in the removal of organic matter, however it presented some limitations in removing nutrients, especially nitrogen, mainly due to the contribution of volatilization of ammonia.
