Treatment of domestic wastewater by anaerobic reactor for the reuse of effluent in agricultural crops. Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.14, pp.237-249.  Epub 31-Ago-2021.

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.
