Implementación de un Sistema de Tratamiento de Aguas Negras con Tanquez de Sedimentación de Acción Ecológica.

Abstract

This research took place in the ecosystem surrounding the PVC (polyvinyl chloride), accessories factory belonging to JL distributor, which is located in the province of Santo Domingo de los Tsáchilas. It was conducted the implementation of a sewage treatment system by settling tanks of ecological action; it was measured the pollution rate considering an experiment during two stages of assessment (before vs, after), by following descriptive statistics. When working on an initial environmental survey it was noticed that the hydrography was contaminated while the climatic conditions showed a decrease in the native fauna due to human activity, furthermore, the waste water flow through white pipes without any treatment and high turbidity levels. During the second stage of this study; the analysis of sewage after the implementation of water treatment it was observed a noticeable change in its Ph whose rate reached a significant increase compared to untreated water since it rises from 5,85 to 6,70 reaching neutrality. Another factor that was considered was the color whose rate reported a considerable decrease because its initial rate 1215,67 Pt-Co, dropped to 486,27 Pt-Co. Regarding to the fats and oils content their rate decreased significantly since its initial rate of 28,78 dropped to 11,96 similarly, the suspended solids whose rate of 103,19 ppm suffered a decrease to 39,55 ppm. For this reason it is suggested a better handling and storage of solids waste since, it was noticed complete ineffectiveness when collect them for later disposal this leads to develop contamination vectors (mosquitoes, rodents, etc.), and generates a negative visual impact around the industry.
