Photocatalysis process applied to remove Recalcitrant compounds in Industrial Wastewater

摘要

A process of photocatalysis for the Decontamination of water polluted with Recalcitrant substances characterized in that it comprises: a) a step of Transport of Wastewater contaminated with Recalcitrant actors Towards a Recirculation Tank (T - 1 and T (2) (b) a step of adding C Atalizador consists of 75% 25% anatase and Rutile, the Recirculation Tank (t-2).(c) a step of Transport of polluted Wastewater Recirculation Tank (T 2) to a Collector System. (d) a step of recycling of treated water in the collector system to achieve a reduction of Pollution according to subsequent uses, from 25 to 35% as Cod.(e) a Sedimentation Stage t-2 and t-3) suspension contained in the Recirculation Tank to recover the Catalyst. (f) a phase of water transport to the Recirculation Tank, a Storage Tank (t-4 and t-5) to be reused or discharged effluent.The process of photocatalysis for the Decontamination of water polluted with Recalcitrant substances of claim 1, wherein the Recalcitrant actors from Textile Industries, Graphics and / or agrochemical.The process of photocatalysis for the Decontamination of water polluted with Recalcitrant substances of claim 1, wherein the solar collector system has a system of Fluid Reynolds Number higher than 15 000.The process of photocatalysis for the Decontamination of water polluted with Recalcitrant substances of claim 1, wherein the flow can vary between 15 to 50 mm l / l / mm. The process of photocatalysis for the Decontamination of water polluted with Recalcitrant substances of claim 1, wherein the concentration of Catalyst is between 0.2 and 0.8 g / L.
