Summary: | The invention relates to an integrated system of a methanogenic anaerobic reactor and membrane bioreactor, and to a method for the elimination of organic material and nitrogen from urban and industrial wastewater, preferably with COD concentrations of between 150 and 5000 mg/l and where the total nitrogen elimination is between 15 and 50 mg/l, at temperatures higher than 15 DEG C. The purification of the wastewater is carried out over three treatment steps: a methanogenic anaerobic step, an anoxic step with biofilms and biomass in suspension, and an aerobic filtration step with biofilms and biomass in suspension.
Sistema integrado de reactor anaerobio metanogénico y biorreactor de membranas, y procedimiento para la eliminación de materia orgánica y nitrógeno en aguas residuales urbanas o industriales, preferiblemente con concentraciones de DQO comprendidas entre 150 y 5000 mg/L y donde las eliminaciones de nitrógeno total que se producen están comprendidas entre 15 y 50 mg/L, a temperaturas superiores a 15ºC. La depuración del agua residual tiene lugar gracias a tres etapas de tratamiento: etapa anaerobia metanogénica, etapa anóxica con biopelículas y biomasa en suspensión y etapa aerobia de filtración con biopelículas y biomasa en suspensión. |
