Construcción de un prototipo fenton coadyuvante de tratamientos biológicos para lixiviados en el Relleno Sanitario Porlón.

Abstract

The aim of this qualification work was to build a Fenton prototype of biological treatments for leaching in the Porlón sanitary landfill. The initial sample of the leachate was characterized by a physical-chemical analysis, whose parameters to be determined were: pH, Total Dissolved solids (TDS), conductivity, alkalinity, turbidity, color, Biochemical Oxygen Demand (BOD5) Chemical Oxygen Demand (COD) and Tense active. This will be taken as a control parameter the turbidity and heat. The equipment was dimensioned, with the results obtained it was designed the plane of AutoCAD. Based on these specifications, the equipment was built on glass, metal and stainless steel materials. In Fenton oxidation, a combination of H2O2 and FeSO4 in acidic conditions was used. As a result we have this elaborated equipment for 1l of leachate to treat, with an initial speed of 30 rpm to 0,77 hp and final speed of 100 RPM to 1,33 hp controlled by a variator sinamics G 110. Working conditions were 120 minutes, pH of 3,400 mg/LH2O2 and 1000mg/L Fe2+. The percentages of organic matter removal measured from turbidity and color were 91% and 87% respectively. While removal BOD5, COD, and TDS were 85%, 72% and 66% respectively. Thus obtaining a greater removal in comparison with other techniques.
