Resumen en español En este trabajo se evaluó la degradación fotocatalítica de contaminantes acuosos provenientes de una industria de productos químicos, empleando un fotorreactor solar de placas planas de vidrio corrugado dispuestas en forma de cascada, sobre las cuales se soportaron películas de TiO2 (Degussa P-25) / SiO2, como sistema fotoactivo. Se estudió la influencia de tres variables en la eficiencia de descontaminación: cantidad de H2O2, volumen de agua a tratar y cantidad de (mas) TiO2 disperso, mediante un diseño de experimentos llevados a cabo en modo de operación discontinua por un periodo de 5 horas para cada ensayo. Los resultados obtenidos confirman a la Fotocatálisis Heterogénea (FH) como una tecnología viable de tratamiento en etapas previas a un tratamiento biológico ya que se alcanzaron porcentajes de reducción en la DQO que varían entre 6 y 46% y se obtuvieron efluentes biodegradables en todas las pruebas realizadas. Resumen en inglés Wastewater of a chemical industry was treated in a photocatalytic process, using a solar photoreactor made of glass corrugated flat plates that had been set in cascade and using Titanium Dioxide (Degussa P-25) as photocatalyst that is supported on each one of them in film form. The influence of three variables in the decontamination efficiency were studied: amount of H2O2, volume of water and amount of dispersed TiO2, by means of the accomplishment of fifteen experiments (mas) carried out in discontinuous operation mode by a period of 5 hours for each test. The obtained results allow to establish that the FH is a viable technology of treatment like previous stage to a biological treatment since percentage of reduction in the DQO varies between 6 and 46% and was managed to reach a biodegradable effluent in all tests.

Resumen en inglés The electro-bioremediation is a technique that is used for the remediation of hydrocarbon contaminated soils. The aim of this study is to explore the electro-bioremediation of an unsaturated soil, contaminated with hydrocarbon waste generated by the oil industry activity in the area and previously remediated by landfarming, to in order to increase the removal of polyaromatic hydrocarbons. The sample was put in a three-compartment electro-bioremediation glass cell of 58 cm (mas) long, the lateral compartments containing the electrolyte; we used bridges of ammonium phosphate to connect the electrolyte with the soil sample in the central compartment. A potential difference of 0.5 V cm-1 was applied to the electro-bioremediation cells for 60 days. A second cell was used for control and no current was applied to it. The monitoring was carried out by a counting cell and measuring of n-alkanes and polyaromatic hydrocarbons using GC mass. The results showed that this technology has good potential to increase the biodegradation of n-alkane hydrocarbons and polyaromatic hydrocarbons such as phenanthrene, 1-3-metilphenanthrene, chrysene, 3-methylchrysene, 6-methylchrysene, benzo(b)fluoranthrene and benzo(ghi)pyrene which, without the application of direct current, were not biodegraded by microorganisms in the soil. The use of salt bridges maintained the pH between values that are compatible with the degrading bacterial community.
