RESUMEN: La investigación se realizó para evaluar la eficiencia de humedales artificiales de Shoenoplectus californicus (totora) y Nasturtion officinale (berros) sobre los contaminantes de efluentes de granja de porcinos en Huancavelica. Para determinar la eficiencia de cantidad de la materia orgánica removida por los humedales artificiales se determinó la demanda química de oxígeno (DQO) y oxígeno disuelto (OD), para esto se utilizó el digestor y el colorímetro portátil Hach DR900. Los resultados obtenidos de la eficiencia del humedal artificial de la totora al ingreso y salida fue de 559.45 mg/l y 118.15 mg/l de DQO, de 1.11 a 8.25 mg/l OD, de 843.19 a 534.98 mg/l de conductividad eléctrica, 13.49 a 13.49 ℃ de temperatura, 6.74 a 7.36 de pH, y para el humedal artificial de berros fue de 559.45 mg/l y 118.00 mg/l de DQO, 1.11 a 3.07 mg/l OD, 843.19 a 642.48 mg/l de conductividad eléctrica, 13.49 a 13.32 ℃ de temperatura, 6.74 a 7.29 de pH respectivamente. En conclusión, la eficiencia de los humedales artificiales de Schoenoplectus californicus (totora) es de 78.88 % y Nasturtion officinale (berros) 78.91%, en la remoción de contaminantes del efluente de la granja de porcinos en Huancavelica.
ABSTRACT: The investigation was carried out to evaluate the efficiency of artificial wetlands of Shoenoplectus californicus (cattail) and Nasturtion officinale (watercress) on the pollutants of effluents from the pig farm in Huancavelica. To determine the efficiency of the amount of organic matter removed by the constructed wetlands, the chemical oxygen demand (COD) and dissolved oxygen (DO) were determined, for this, the digester and the portable Hach DR900 colorimeter were used. The results obtained from the efficiency of the artificial reed wetland at entry and exit was 559.45 mg / l and 118.15 mg / l of COD, from 1.11 to 8.25 mg / l DO, from 843.19 to 534.98 mg / l of electrical conductivity, 13.49 at 13.49 ℃ of temperature, 6.74 to 7.36 of pH, and for the artificial watercress wetland it was 559.45 mg / l and 118.00 mg / l of COD, 1.11 to 3.07 mg / l DO, 843.19 to 642.48 mg / l of electrical conductivity, 13.49 to 13.32 ℃ of temperature, 6.74 to 7.29 of pH respectively. In conclusion, the efficiency of the artificial wetlands of Schoenoplectus californicus (totora) is 78.88% and Nasturtion officinale (watercress) 78.91%, in the removal of pollutants from the effluent of the pig farm in Huancavelica.
