| Résumé | BACKGROUND: Anaerobic digestion of agricultural wastes is a cost effective way for combining resource recovery and methane production. This paper evaluates the co-digestion of cow manure and switchgrass in a completely stirred tank reactor (CSTR) by the electrolysis-enhanced anaerobic digestion (eAD) process. RESULTS: The electrodes for water electrolysis were installed directly in an anaerobic digester and were used to create micro-aerobic conditions. Significant gains in process performance and biogas quality were obtained at current densities of 20-25 mA LR-1 (per digester volume) with a corresponding volumetric energy consumption of 0.07-0.08 Wh LR-1. In particular, the COD removal rate was increased from 0.6 to 0.9 g COD LR-1 d-1, methane production increased by 26%, and H2S content in the biogas declined from 2500-3000 ppm to less than 10 ppm. CONCLUSIONS: The improved performance was achieved due to methane production from hydrolytic H2 and possibly due to the enhanced hydrolysis of organic matter. |
