Chemical Modeling of a Dairy Waste/Water Management, Pollution Control System for Farm Management in Puerto Rico

摘要

This project involved the establishment of a chemical model of a waste management system on a small dairy farm, with the intention that such a model could be used as a basis for evaluation and optimization of the system. The system used involved water flushing of dairy animal wastes into a temporary holding tank in which the diluted wastes are chopped and homogenized. The homogenized slurry is then pumped either to a large anaerobic lagoon, where microbial degradation of organic and inorganic components takes place or for the charging of an anaerobic digestion tank for the production of methane gas, which can then be used as a fuel for electricity production. Lagoon water is used for field irrigation.
