Tratamento de efluente proveniente da bovinocultura leiteira

Abstract

The milk-cattle culture it’s a very important department of Brazilian and world agribusiness, responsible for feed and income generation for big part of population, but it’s an activity that can deteriorate a lot the environmental quality, being an straight pollution source or diffuse in the rural environmental if not properly managed. Thus, this present work’s objective was implement an effluent treatment system, consisting of an anaerobic lagoon followed by a facultative pond on a property located in a rural area within the city of Pato Branco – PR, which develops cattle culture and didn’t count with any effluents treatment system. In addition to the implementation, the system was controlled and monitored, being realized 3 (three) Biochemical oxygen demand analysis (BOD), monthly, In order to determine the removal efficiency of BOD in the system. At the end of this work was possible observe an significant reduction in the polluting potential of the effluent, achieve 85% of efficiency in the removal of BOD, reaching the requirements recommended in Resolution CONAMA 430 of 2011 also demonstrating that the proposed treatment is technically and economically practicable in properties which develops the milk-cattle culture.
