Abstract

La invención se refiere a un procedimiento de tratamiento de fangos residuales para optimizar la producción de biogás y la calidad del mismo, así como la calidad del fango final obtenido. El procedimiento comprende las etapas de realizar una hidrólisis y extracción de metales previa de los fangos residuales, centrifugar para separar el sobrenadante que comprende metales del fango sedimentado, y someter el fango sedimentado a digestión anaerobia en condiciones microaerofilicas en un digestor anaerobio de mezcla completa para la eliminación de H2S.
