Abstract
Procedimiento para la eliminación de metales pesados del lodo de depuradora de instalaciones industriales o comunales, constituido por los pasos: (a) calentamiento del lodo de depuradora en una etapa de reducción bajo exclusión de oxígeno a temperaturas entre 500º a 1100ºC, (b) calcinación posterior del coque de lodo de depuradora formado en el paso (a) en una etapa de oxidación a temperaturas entre 800 y 1200ºC, en la que el total del carbono residual se convierte en energía térmica.
Description
La invención se ilustra en los siguientes ejemplos. Ejemplos: En los ejemplos expuestos continuación se llevaron a cabo en total ocho diferentes disposiciones de ensayo. Disposiciones de ensayo:
- 5 1. Material de partida: lodo de depuradora, deshidratado y previamente secado hasta > 60% de sustancia seca
- 2.
- Lodo de depuradora después de la etapa de reducción (tratado de forma reductora)
- 3.
- Lodo de depuradora con adición de MgCl2 en la etapa de reducción (tratado de forma reductora)
- 4.
- Lodo de depuradora después de la segunda etapa de oxidación (calcinado posteriormente de forma oxidativa).
- 10 5. Lodo de depuradora con adición de MgCl2 después de la segunda etapa de oxidación (calcinado posteriormente de forma oxidativa)
El lodo de depuradora, deshidratado y previamente secado, se sometió a una pirolisis de forma correspondiente a
las variantes de ensayo individuales V1, V2, V3, V4, V5, bajo condiciones reductoras en la etapa de reducción, a una
temperatura de 800ºC durante 1 hora.
15 A continuación, las variantes de ensayo V4 y V5 se volvieron a calcinar de forma oxidativa en la subsiguiente etapa de oxidación a temperaturas de 1000ºC durante 1 hora. Para cada variante de ensayo se determinó la solubilidad del fosfato después del tratamiento reductor y de la calcinación posterior.
En la Tabla 1 se muestran los rendimientos en fosfato de las distintas variantes de ensayo, así como la carga de metales pesados después de la etapa de reducción y la etapa de oxidación.
20 En la fase oxidativa casi la totalidad del carbono residual se pudo transformar en energía térmica.
