Diseño y construcción de un reactor Batch prototipo para la obtención de compost con residuos orgánicos generados en la Escuela Superior Politécnica de Chimborazo.

Abstract

The objective was to design and construct a prototype batch reactor to obtain compost with organic residues generated at Escuela Superior Politecnica de Chimborazo, for which experiments were carried out on prototypes, which were metallic and plastic tanks of 30 and 200 L respectively. By means of the characterization of the raw material, it was possible to determine a relation C/N = 32.54, which determined the appropriate proportions to be used, being organic residues from the Polytechnic Dining room and 4: 1 pruning residues respectively (RSOV = 54.43 Kg and Pruning = 13.61 kg), with this proportion and with a periodic monitoring, a suitable medium was determined that simulates aerobic characteristics controlling the process parameters such as: temperature, pH, humidity and electrical conductivity, and to determine the process variables to control in the equipment, which are: the turning, aeration and elimination of leachate. Emphasizing these aspects, a compost was obtained, which was characterized, resulting in that the product is within the parameters based on the Environmental Standard for the Federal District NADF-020-AMBT-2011 of Mexico and also the standard NCh2880 ruled in Chile, which regulate the quality of it, since Ecuador has no rules. It was constructed and proceeded to the validation of it by the elaboration of compost, with the same parameters mentioned in previous experiments, which has indicated that the reactor to elaborate compost works properly, since its performance and efficiency have been the most optimal due to it will be widely used in the institution. It is recommended that for further experiments in the equipment, respective analyzes are carried out previously to determine suitable formulations of substrate to be treated.
