Resumo: The objective of this study was to evaluate the efficiency of substrates and vegetal species to treat sanitary wastewater, in a subsurface downward flow root zone system, after previous decantation. The experiment was carried out at Samambaia Campus, Federal University of Goiás, Goiânia, Goiás State, Brazil. The vegetal species were narrow-leaf cattail (Typha angustifolia L.), white ginger (Hedychium coronarium J. König), Job's tears (Coix lacryma-jobi L.), and para grass (Urochloa mutica (Forssk.) T.Q. Nguyen). The system revealed to be efficient on wastewater pollutants removal, meeting the effluent standards established by current Brazilian regulation, except for ammoniumnitrogen. Narrow leaf cattail and white ginger showed to be more efficient on BOD reduction, substrate oxygenation, and ammonium-nitrogen and coliforms removal. Narrow leaf cattail was more efficient on phosphate removal. The efficiency on coliforms removal reached levels close to totality. Coconut fibre was the less efficient substrate for BOD and COD reduction and withdrawal of ammonium-nitrogen and coliforms. KEY-WORDS: Wastewater treatment, constructed wetlands, rootzone.

O presente estudo objetivou avaliar a eficiência de substratos e de espécies vegetais no tratamento de esgoto sanitário, num sistema do tipo zona de raízes com fluxo subsuperficial descendente, após decantação. O experimento foi conduzido no campus Samambaia, da Universidade Federal de Goiás, em Goiânia, Goiás, Brasil. As espécies avaliadas foram taboa (Typha angustifolia L.), lírio do brejo (Hedychium coronarium J. König), conta-de-lágrima (Coix lacryma-jobi L.) e capim Angola (Urochloa mutica (Forssk.) T.Q. Nguyen). O sistema mostrou-se eficiente na remoção de poluentes do esgoto, atendendo aos padrões estabelecidos pela legislação brasileira vigente, exceto para o nitrogênio amoniacal. A taboa e o lírio-do-brejo mostraram-se mais eficientes na redução da DBO, na oxigenação do substrato, na remoção do nitrogênio amoniacal e na remoção de coliformes. A taboa foi mais eficiente na remoção de fosfatos. A eficiência na remoção de coliformes atingiu níveis próximos à totalidade. Dentre os substratos avaliados, a casca de coco foi o menos eficiente na redução da DBO e da DQO e na remoção do nitrogênio amoniacal e dos coliformes.
