Caracterização físico-química dos efluentes líquidos oriundos de uma oficina automotiva: estudo de caso

Abstract

This work was to demonstrate the strong thematic automotive growth in Brazil and how this car market is competitive, innovative and how it affects the environment, especially in relation to automotive painting that is now a competitive differentiator. Data collection was conducted through exploratory research, through a literature review of the state of the art of the main methods of wastewater treatment. This process has the use of paints and solvents, their use is highly dangerous to the environment and the ecosystem that has contact, the greater concern is the final destination given to these materials, since the process uses too much water and the same this being directed and mixed with municipal waste and sent to a water body near the place of work. Three points of different collections and four distinct parameters to be analyzed, to get a real characterization were established, the results indicated high concentrations for all parameters analyzed - 1323.33 COD, BOD 545.7700, 242.6667 Oils and Greases and Totals Total solids 5020.5000. All values were outside the resolutions allowed by current standards, the biggest problem encountered is launching in nature. CONAMA, by - another important report that to define the degree of pollution of the effluent have to take into account that Brazil has, where it has federal legislation specific to the effluent discharge established by the National Council on the Environment section through resolution No. 430 of May 13, 2011. The resolution determines the maximum values allowed for the release of domestic sewage and effluents from any pollution source.
