Degradacion del fenol presente en las descargas de aguas residuales industriales de la Refineria de Shushufindi mediante foto oxidacion catalítica homogénea y heterogénea para descontaminacion de sus descargas

Abstract

This phenol was degraded in the discharge of industrial wastewater Shushufindi refinery by homogeneous and heterogeneous catalytic photooxidation for decontamination of its downloads. Water samples were collected from industrial discharges of Amazonas Shushufindi refinery industrial complex 1 of EP Petroecuador in the province of Sucumbíos, through the characterization of the samples was determined that phenol was at a concentration of 0.100 ppm. For the heterogeneous photocatalytic treatment it was used one photoreactor drum 20L. PVC tubing, hoses, anatase (TiO2) titanium impregnated into a UV sterilizer dioxide as a catalyst and a UV lamp with a wavelength of built 240-280 nm for 24 hours of treatment at an acid Ph. . For homogeneous treatment called photofenton hydrogen peroxide was used as the oxidant and iron II at an acid ph. treated by exposure to sunlight for 60 minutes, the amount of phenol degraded was analyzed at the center for Technical Services and Environmental Technology Transfer located on the Polytechnic School of Chimborazo, with the result that for the heterogeneous treatment was downgraded 0.046 ppm of phenol that is 46%and for homogeneous treatment was downgraded 0.057 ppm which is 57% of phenol, both treatment were adjusted to ph. 3 being more optimal for pollutant degradation. We conclude that both treatments are effective for the degradation of phenol present in industrial waters. It is recommended to use these treatments due to low cost, and the less time consuming compared to other treatments to degrade this type of pollutant.
