ADEQUAÇÃO DO SISTEMA DE ESGOTAMENTO SANITÁRIO PRÓXIMO AO CÓRREGO DOS BAMBUS, NO MUNICÍPIO DE TRÊS PONTAS – MG.

Abstract

The present work is a study of sanitary sewage for the city of Três Pontas - Minas Gerais, integrating the neighborhoods Botafogo, Ouro Verde, Hope, Sun Valley, João Piedade Campos, Santana besides that part of Centro, where the sewage is released in natura, directly in the Córrego dos Bambus. Interviews were initially conducted with professionals from the Serviço Autônomo de Água e Esgoto (SAAE) and also from the Três Pontas municipality, who provided data for this study. To elaborate the diagnosis of sanitary sewage, it was necessary to map the site through technical and planialtimetric drawings, as well as on-site visits to verify the existing collection networks. The diameter of the networks and the flow rates corresponding to each section were verified, identifying the absence of an interceptor network and the sewage treatment system, which was released directly into the Córrego dos Bambus_. Therefore, it was necessary to design an interceptor network and sewage treatment system for the site. According to analyzes and studies carried out in technical literature, it is concluded that the type of treatment station most suitable for site implantation is the UASB Reactor type, presenting treatment efficiency of 66.124% of biochemical oxygen demand and 74.130% of chemical demand. higher than CONAMA Resolution 357/05. The cost to implement the adjustments will be 1.224.917,81 reais for the interceptor and 645.144,51 reais for the sewage treatment plant, the station will also have a cost of 42.423,06 reais / year for operation and maintenance.
