Abstract
El presente trabajo de investigación tuvo como objetivo poder utilizar humedales construi-dos de flujo superficial en 2023 para tratar las aguas residuales de Covicorti para el riego de parques y jardines de la ciudad de Trujillo. El diseño fue de tipo experimental con el fin de evaluar los parámetros fisicoquímicos y microbiológicos de las aguas residuales, así mismo analizar el cambio de sus concentraciones mediante diversas evaluaciones en el laboratorio Sedalib S. A., la población de estudio conformada por el líquido sobrante que fluye de la instalación final de la Estación Depuradora de Aguas Residuales de Covicorti, así como el vertido líquido de aguas residuales de una fuente, con una muestra de 0,95 metros cúbicos de agua residual dispuesta a el humedal artificial. Se analizó estos resultados mediante la norma FAO, EPA y el D.S. N° 004-2017-MINAM, donde, el análisis del agua residual de la PTAR Covicorti mostró niveles de DBO5, DQO y coliformes termotolerantes por encima de los estándares permitidos, mientras que los humedales artificiales de flujo superficial, con un pH de 7,43 - 7,73 y temperaturas entre 23,4 °C y 23,3°C, presentaron un oxígeno disuelto de 6,65 mg/L y DBO5 de hasta 14,28 mg/L, así mismo, redujeron sólidos suspendidos y metales pesados. Se concluye que el tratamiento es efectivo a la norma nacional dada por el MINAM y es posible el uso de las aguas residuales para regar las áreas verdes previo trata-miento.
The aim of this research work is to be able to use constructed surface flow wetlands in 2023 to treat wastewater from Covicorti for the irrigation of parks and gardens in the city of Tru-jillo. The design is experimental in order to evaluate the physico-chemical and microbiolog-ical parameters of the wastewater, as well as to analyse the change in its concentrations through various evaluations in the Sedalib laboratory, the study population comprised of the excess liquid flowing from the final installation of the Covicorti Wastewater Treatment Plant, as well as the liquid discharge of wastewater from a source, with a sample of 0,95 cubic metres of wastewater disposed of in the artificial wetland. These results were analysed using the FAO, EPA and D.S. N° 004-2017-MINAM, where, the analysis of the wastewater from the PTAR Covicorti showed levels of BOD5, COD and thermotolerant coliforms above the permitted standards, while surface flow constructed wetlands, with a pH of 7,43 -7,73 and temperatures between 23,4°C and 23,3°C, had dissolved oxygen of 6,65 mg/L and BOD5 up to 14,28 mg/L, as well as reduced suspended solids and heavy metals. It is con-cluded that the treatment is effective according to the national standard given by MINAM and it is possible to use the wastewater for irrigation of green areas after treatment.
