Resumen:
Industrial production of poultry meat is associatedwith indirect environmental impacts such as contributingto climate change and deforestation and otherdirect impacts such as the deterioration of the quality ofsurface waters. Poultry industry effluents are rich inorganic matter, nitrogen, and phosphorus; nutrients canbe removed from wastewater through the use of macrophytesand periphyton. An essay in mesocosms withpoultry industry wastewater recirculation was developedin the presence and absence of a native macrophyteSpirodela intermedia and periphyton from a lowlandstream (La Choza stream, Buenos Aires) where theeffluent is poured. The diffusion of O2, increased bywater recirculation, had the effect of increasing theconcentration of dissolved oxygen in wastewater. Thepresence of S. intermedia and algae periphyton significantlycontributed to the removal rates (%) of solids(69.7 ± 3.9), ammonium nitrogen (84.0 ± 3.4), and totalphosphorus (38.1 ± 1.8) from residual water and favorednitrification. The dominance of Bacillariophyceae onother groups of algae of periphyton and the low representationof Euglenophyceae indicated an advancedstage of the effluent treatment process at the end of theassay.
