Abstract

In the decolorization treatment of molasses wastewater by electrolysis, the effect of anode material on the decolorization efficiency (<i>η</i>) was studied. Five soats of anode material, which are PdO, PbO<sub>2</sub>, IrO<sub>2</sub>, Pt and graphite, were certified under the electrolysis condition of wastewater from an alcohol distillery with 5% NaCl. PdO was the most effective anode. <i>η</i> with PdO was 750U·<i>l</i>·kC<sup>-1</sup> three times larger than <i>η</i> with Pt, and <i>η</i> with graphite was 470U·<i>l</i>·kC<sup>-1</sup>. In order to study for practical use, the pilot scale electrolysis reactor was made with a graphite anode and a stainless steel cathode. When methane fermentation was used for pre-treatment and the treated water diluted with sea water, <i>η</i> was obtained the highest value. The energy balance of the glutamate wastewater treatment system which was conbined a methane fermentation, electrolysis decolorization and co-generation was estimated. The recovery electric energy from co-generation was calculated as 75% of the required electric energy for electrolysis decolorization.
