Description
Summary:The swine confinement farms and the improper disposal of their wastes carry result in contamination of water and soil. On many farms is common slurry application to soil as a means of fertilization, but without any control over the quality of the effluent being released. What is a parasite Ascaris suum from pigs can infect humans, but is not given due importance to the presence of this contaminant as soil and water. In this work the effluent of a pig was treated in a system composed of anaerobic baffled reactor (ABR) and a UASB followed by polishing ponds for removal of helminthes eggs. The experiment was conducted at the Hélio Barbosa Experimental Farm pig in the city of Igarapé / MG. Values found in the influent of helminthes eggs in the range from 2891 to 88,848 eggs L-1, while the effluent showed absence of eggs, showing the high efficiency of the treatment system. While the sludge ponds, it showed high concentration of viable eggs ranged from 10.1% to 59.8%, not being in conformity with the requirements for reuse in agriculture.
