Eficiência do sistema de tratamento de efluentes de um abatedouro frigorífico

Abstract

Daily the slaughterhouses generate huge effluent liquids volumes. Therefore, it is a challenge environmental adequacy and treatments efficiency. All industrial waste generated needs alternatives to their treatments and proper deposition, attending to current legislation to reach the required standard to be released into hydric bodies. Facing this scenario, the aim of this research was to analyze the stabilization ponds system efficiency used in the effluent treatment of a slaughterhouse freezer on the municipality of São Gabriel – RS. In order to analyze the efficiency were collected input and output effluents of the system. In order to do the physic-chemical analysis were utilized the equipment: Pastel UV – portable spectrophotometer, pH meter, colorimeter, turbidimeter, and oximeter. With the intention of evaluating efficiency was took as reference the resolutions CONAMA 347/2005, 430/2011 and the CONSEMA 128/2006. Due to this study has verified the efficiency on all analyzed parameters. The respectively obtained results were, 88,17%; 86, 29%; 77,15%; 86,89%; 89,86%; being 85,67% as result of global efficiency. However, there is the necessity to develop environmental management strategies to improve the results efficiency.
