Abstract

La presente invención se refiere a un procedimiento para la eliminación de compuestos orgánicos presentes en aguas residuales que comprende una etapa de degradación biológica en donde el efluente se trata con bacterias en un medio que contiene sales y un surfactante no iónico, seguido de una etapa de extracción líquido-líquido de los compuestos orgánicos no metabolizados anteriormente utilizando un surfactante no iónico y una sal como agente de segregación de fases.The present invention relates to a process for the elimination of organic compounds present in wastewater comprising a stage of biological degradation wherein the effluent is treated with bacteria in a medium containing salts and a non-ionic surfactant, followed by a step of Liquid-liquid extraction of organic compounds not previously metabolized using a non-ionic surfactant and a salt as phase segregation agent.
