Diseño de un biodigestor para la producción de biol a partir de excretas de ganado vacuno generado en la Finca “La Envidia” parroquia La Belleza, cantón Francisco de Orellana, Coca.

Abstract

The purpose of this research was to design a bio-digester for the production of liquid effluent from cattle manure generated on the farm “La Envidia” in the Ecuadorian Amazon. This project used anaerobic digester based on Chinese design as its source of innovation. A prototype was used with appropriate monitoring to generate liquid effluent production on the grounds of the farm “La Envidia”, in the Francisco de Orellana Canton, Orellana Province. The bio-digester was designed according to the parameters of the cattle region of the Ecuadorian Amazon. Seven beef castle were included as part of the research and produced 0,21m XVI

3 /hour, which was stored in the prototype with a composition of 1:1 water and a retention time of 30 days. The temperature and pH are basic microbiological processes for anaerobic digestion and thus were measured daily. After 30 days two random samples were taken in order to evaluate the development of liquid effluent. Among the parameters to determine the quality of the liquid effluent the following were taken into account: Total Nitrogen, Potassium and Phosphorus and the results obtained were 100%, 98.87%, 61.16% effectiveness respectively. With appropriated physicochemical parameters for the prototype, the blueprints for feeding was sized to 0,17m 3 forthebio-digestertankgenerating a maximum capacity of 5.48m 3 and a dome biogas as a byproduct storing the amount of 0,66 m 3 . It was concluded based on the calculations performed with a retention time of 30 days that theoretical production would be 5.11m 3 liquid effluent per month. It is recommended that for the design of bio-digester, it would operate on a minimum of 18 m2 , in a flat place for the entry, bio-digester, and output. The recommended sludge box position is on land with a 30% slope at the base of the bio-digester.
