Abstract
RESUMEN: El objetivo de la investigación fue evaluar el tratamiento de aguas residuales domesticas mediante reactor anaerobio y su influencia significativa en la reutilización del efluente en cultivos agrícolas. La investigación realizada fue de tipo experimental, nivel descriptivo-explicativo, investigación aplicada. Como resultados se obtuvo que la norma DS N°003-2002-PRODUCE, establece los límites máximos permisibles y valores referenciales para la actividad en la reutilización con un pH entre 6-8, temperatura <35°C, se dispuso de la toma de muestra de la laguna de oxidación de Cachiche, como lo indica las coordenadas UTM, la biomasa anaerobia fue obtenido de Yaurilla-Parcona, se analizó el afluente tabla 5 y tabla 6, en las fechas indicadas a horas 8:00 am., (06.02.2021), y a horas 10:00 am., (02.04.2021), Discusión se evidenciaron que los resultados de caracterización ARD-010-A y ARD-020-B, influenciaron en la reutilización del efluente en cultivos agrícolas. Para finalizar se tiene que la reutilización del efluente en cultivos agrícolas depende del tratamiento con reactor anaerobio en el tratamiento de aguas residuales se obtuvieron para las 32 horas con pH de 7.7; solidos suspendidos 38 mg/l y para los coliformes termo tolerantes un valor 890 NMP/100ml; valores que se encuentran por debajo de los estándares de calidad ambiental ECA AGUA para su reusó en la Categoría 3: Riego de vegetales y bebida de animales del DECRETO SUPREMO N° 004-2017-MINAM.
ABSTRACT: The objective of the research was to evaluate the treatment of domestic wastewater by means of an anaerobic reactor and its significant influence on the reuse of the effluent in agricultural crops. The research was of experimental type, descriptive-explanatory level, applied research. As results it was obtained that the norm DS N°003-2002-PRODUCE, establishes the maximum permissible limits and referential values for the activity in the reuse with a pH between 6-8, temperature <35°C, the sampling of the oxidation lagoon of Cachiche was available, as indicated by the UTM coordinates, the anaerobic biomass was obtained from Yaurilla-Parcona, the affluent was analyzed table 5 and table 6, on the dates indicated at 8:00 am. hours, (06.02.2021), and at 10:00 a.m. (02.04.2021), Discussion showed that the characterization results ARD-010-A and ARD-020-B, influenced the reuse of effluent in agricultural crops. To conclude we have that the reuse of effluent in agricultural crops depends on the treatment with anaerobic reactor in the wastewater treatment were obtained for the 32 hours with pH of 7.7; suspended solids 38 mg/l and for thermotolerant coliforms a value 890 NMP/100ml; values that are below the environmental quality standards ECA WATER for reuse in Category 3: Irrigation of vegetables and animal drinking of the SUPREME DECREE N° 004-2017-MINAM.
