摘要: Abstract This study evaluated the potential of earthworms (Eisenia fetida) to remove pathogens from sludge septic tanks. Three earthworm population densities, equivalent 1, 2, and 2.5 kg m-2, were tested for pathogen removal sludge. The experimental phase lasted 60 days, starting initial inoculation. After it was found that reduced concentrations fecal coliforms, Salmonella spp., helminth ova permissible levels ( SEMARNAT, 2002 ). Thus, treatment with generated Class A biosolids, useful forest, agricultural, soil improvement.
