Mapping and verification of the existence of a previous effluent treatment system in the sources of oily effluents in the municipality of Coxim

Abstract

The National Solid Waste Policy determines the mandatory application of reverse logistics to Lubricating Oils, their derivatives and their packaging due the risk that this product offers to  environment, however, it is usually verified the non-fulfillment of this duty by the generating sources of this scrap Therefore, this study aims was to map and diagnose the situation of enterprises that generate this residue in municipality of Coxim, verifying the existence of a previous effluent treatment system in them, which allows their subsequent reverse logistics. In this sense the methodology adopted for the accomplishment of this one was the mapping of the sources by means of visit to the points and annotation of the geographical coordinates of all with the aid of a GPS, later data were processed with help of free software Quantum GIS. There were 40 potentially oily effluent generating points in their activities in the municipality, they are vehicle washers, machine shop, motorcycle mechanics and fuel stations, of which about 83% have effluent pretreatment systems, which are the separator boxes of water and oil, although 7% present their systems with some operating problem or in an inadequate way, the largest amount of enterprises in dissonance with the National Policy are the automotive mechanics, since the fuel stations present 100% efficiency in the previous treatment because they all have water and oil separator boxes. It is concluded with this work that there is a need for automotive mechanics to adapt fully to current policies, such as gas stations, although it is necessary to apply pre-treatment systems for effluent treatment to all potential generators in the municipality, the Coxim city has significantly positive values, since the great majority of enterprises rely on this system which implies in operation of compulsory reverse logistics in the region of study.
