“…However, the decolorization of colored wastewater remains an issue. It is known that carbon can remove the chromaticity and COD components of livestock wastewater 14) . Hennion et al 15) reported that graphite carbon has the property of adsorbing chromaticity components in livestock wastewater and can be leached using an organic solvent, and thus can be used repeatedly, and it is possible to reduce the cost of advanced treatment of livestock wastewater.…”

Aiming at the development of a filter material that can be used for livestock wastewater treatment, a sintered filter was manufactured by combining recycled carbon with ceramics. We investigated the possibility of applying this filter to the decolorization treatment of the color-causing substances contained in wastewater. Humic acid was used as a model of the color-causing substances. The possibility of regenerating a carbon-ceramic sintered filter after the adsorption treatment by heat treatment and repeated use was examined. When an aqueous solution of sodium humic acid was poured into the sintered carbon-ceramic filter, it was found that it has a high adsorption capacity for humic acid. However, when the aqueous solution was continuously poured, the adsorption rate of humic acid decreased. When the sintered carbon-ceramic body used in the adsorption experiment was heat-treated in an air atmosphere, the adsorption capacity was restored through the heat treatment at 400 °C to 500 °C. From the above, it was shown that a sintered carbonceramic body can be an effective adsorbent for humic acid, which is a coloring substance for livestock wastewater and can be repeatedly used for heat treatment.
