Análise ambiental, sanitária e econômica de um sistema de tratamento de resíduos sólidos e efluentes em uma granja de suínos

The swine manure have pollution potential of environmental and sanitary point of view due to the high organic matter content. However, when properly treated, may present potential for generating value-added products. This study aimed to carry out an environmental analysis, health and economic of a solid waste treatment system and wastewater (WTSW) in a technified swine farm full cycle. The WTSW was formed basically by composting, anaerobic digestion and retention and sludge dehydration. Laboratory tests were evaluated in chemical and microbiological physical parameters were performed. The economic viability of WTSW analysis was supported in capital budgeting technique. The WTSW was able to treat organicwaste effluents and rendering them unable to cause environmental and health damage. There was also gain social and reduction of environmental liabilities. In the economic analysis, WTSW will take about nine years to amortize the capital invested.
