Abstract

The objective of this Curriculum Integration Work is to develop an adequate alternative in environmental, economic and profitable terms for the treatment of manure, excreta and urine from a commercial-family pig farm theoretically located in Santo Domingo de los Colorados. For the project proposal, the number of pigs with which the farm would start operating was determined, in addition, the amount of water that each pig requires for its proper development, growth and cleaning was determined, without neglecting the water required by the staff that the farm for consumption, washing and hygiene. The facilities of the pig farm will have a part destined for the pigs and another for the personnel that will carry out the tasks of care and maintenance of the farm. For pigs there are several areas depending on the point of development where they are, that is how it is; a gestation area, a maternity module, a weaning and growth area, a fattening area, a development area for boars, a sales area, a quarantine and acclimatization area, and an area for waste management. On the other hand, the farm has a building or home for the staff who carry out their work on the farm, whether they are administrative, workers or maintenance. Considering the composition of the farm, and in addition to the number and consumption of water that both staff and pigs require, the tanks that together form the farm's water and slurry treatment system were designed. The next step to follow is to determine the type of slurry and excreta treatment system to be implemented on the farm. A septic tank was sized based on the volumes of water required by the farm staff, an Imhoff tank which will receive the slurry, excreta and urine from both the pig sheds, as well as from the septic tank outlets. and finally a drying bed at the end of the line where the sludge from the septic tank and Imhoff digesters will be dehydrated.
