Eficiencia de los microorganismos en la estabilización de lodos sépticos en en el distrito Huando 2021

The unprecedented growth of urban populations has placed enormous pressure on the quality of life with regard to housing, water and energy supply, and this is reflected in the deterioration of the quality of water, air and soil. A decrease in environmental quality due to the generation of waste in these urban centers, especially wastewater, is an important and growing concern. For this, improvement processes for these effluents have been proposed and one of them is the use of efficient microorganisms (EM), in the understanding that bacterial metabolism determines the effectiveness of biological treatment of wastewater. A protocol was designed with five treatments with three repetitions, a control or T0 without ME concentration, T1 2.5% ME in the V/V ratio (volume of solute and volume of solvent).; T2 5%; T3 7.5% and T4 10% to determine the effect of these bacteria in septic sludge in the Huando 2021 district. The organoleptic color and odor characteristics were substantially favored with the presence of ME. Likewise, the concentrations of dissolved solids, ammonium, biochemical oxygen demand; and very in particular, a considerable reduction of the colony-forming units of fecal coliforms. These systems are an alternative for wastewater treatment, they are economical, easy to install, operate and maintain, and are widely used to meet residential demands.
