Investigación de la microbiología en lodos anaerobios provenientes de un biodigestor de alta tasa de una planta de tratamiento de aguas residuales domésticas tipo Tratamiento Primario Químicamente Mejorado (CEPT).

Abstract

The present work will receive continuity to the investigation of microbiology in anaerobic sludges from a high-rate biodigester of a CEPT-type domestic wastewater pilot treatment plant, with the main objective of establishing control parameters in the operation and maintenance of the treatment plant so that microorganisms can reach their maximum performance resulting in a removal of acceptable contaminants from the system that is used as a reference to project the efficiency results in the PTAR of Las Esclusas. To measure the efficiency of removal of pollutants, they will consider previous studies of (Morales, 2016) where average values of Total Coliforms are found in raw sludges that were compared with the values of the sludge treated by the anaerobic biodigester, resulting in a 99.9% efficiency. These treated sludges must comply with the Mexican norm NOM-004-SEMARNAT- 2002 for fecal coliforms and the Peruvian norm NOM-015-2017-HOUSING, CONSTRUCTION AND SANITATION for E. Coli where the maximum permissible limits for proper use are specified and final disposition. Finally, the presence of indicators and modifications including fungi and yeasts confirm the formation of an ecosystem within the anaerobic digestion process, which guarantees the decomposition of organic matter and removal of coliforms in the high-rate biodigester due to operator inhibition Lac.
