Determinación de la eficacia del proceso de electrocoagulación en el tratamiento de lixiviados del botadero controlado del cantón francisco de orellana

Abstract

The present research was as aimed to determine the effectiveness electrocoagulation process in the treatment of leachates from the controlled dump from Francisco de Orellana canton. This controlled dump leachates are produced by climatic factors, which constitute a high risk of contamination due to their high concentration of toxic compounds, it puts in risk to the population and ecosystems. Techniques and instruments were used, such as a field visit to collect information, laboratory analysis, review of current regulations and application electrocoagulation process. The results obtained were characterization physicochemical properties of leachate, parameters that are outside the maximum permissible limits established in current TULSMA regulations, book VI table 9, such as color, biological oxygen demand, chemical oxygen demand, total solids, and turbidity, which are highly contaminating. Design and construction variables were considered prototype for leachates based on an acrylic glass reactor measuring 28cm long, 21cm wide and 11cm high; using 5 plates 15cm long and 10cm wide, placed at 4cm between the plates and a power source 0-5 amps and 0-15 volts. The treatment with the highest percentage of pollutant removal was obtained from a voltage 2.5 and 20 minutes with a reduction of 85.23 percent for chemical oxygen demand. In conclusion, there is not a good management in treatment of leachates that originate in the dump, so it is proposed to determine, effectiveness in treatment of leachates through the process of electrocoagulation to control and minimize the negative impacts that are generated to the environment.
