Dinâmica da população de coliformes durante a compostagem automatizada de dejetos líquidos de suínos

Abstract: RESUMOMicrorganismos presentes em dejetos de suínos podem contaminar o meio ambiente. Embora a compostagem seja preconizada como um método eficiente para reduzir este potencial poluidor dos dejetos, existem poucas informações de pesquisa sobre tal processo. O presente trabalho teve o objetivo de avaliar a eficiência da compostagem automatizada dos dejetos líquidos de suínos (DLS) na redução da população de coliformes, usados como indicadores de poluição fecal. Os DLS foram adicionados periodicamente, durante 1… Show more

“…In 2016, Brazil produced 3.73 million tons of pork, mostly in landless farms, which ranks them in fourth place in the world top statistics after China, the European Union, and the United States [9]. However, this also means a large production of (solid and liquid) manure and other wastes that can be found on an intensive farm [10]. Therefore, Brazil has to face a double challenge in the next few decades: (a) increasing its meat production aimed at feeding local people and maintaining exports, and (b) managing farm manure properly in order to reduce their negative impacts (e.g., water pollution).…”

“…Com isso, podem ocorrer a adição de coliformes totais (Sá et al, 2014) e o acúmulo nos solos de Cu, Zn e Mn (Basso et al, 2012), P e K (Scherer et al, 2010), além de N, com riscos de lixiviação e contaminação das águas superficiais e subsuperficiais (Hernández et al, 2013), que podem ocasionar sérios problemas de contaminação ambiental. Por isso, em sistemas tão intensivos como esses, o monitoramento permanente da qualidade dos solos é um processo fundamental à sustentabilidade da atividade agrícola.…”

“…Research on the agronomic potential, greenhouse gas emissions, and pathogens associated with these types of wastes is quite extensive, with numerous studies published over the past decade alone (e.g., SÁ et al, 2014;BROETTO et al, 2015;CARVALHO et al, 2015;GONZATTO et al, 2016). However, evaluations are needed to testthe relative effectiveness of methods applied to waste treated by automated composting, which involves substrate material that provides a greater adhesion area for helminth and protozoa eggs.…”

“…Automated composting, an aerobic process in which liquid pig manure (LPM) is distributed and mixed with a solid matrix (typically wood shavings and sawdust) that provides aeration and steam precipitation of the compost, is one potential alternative for treating LPM (SERPA et al, 2013). For optimal results, the process requires thermophilic temperatures to be attained via the mixing of substrates with material that has a high carbon:nitrogen (C:N) ratio, thereby increasing aerobic microbial activity (SÁ et al, 2014). Such high temperatures are essential to sanitize composted manure, as they incapacitate any parasites that may be present.…”
