Abstract
This study was performed with electrolysis treatment method for improving anaerobic digestion gas production efficiency in a sewage sludge, thereby confirmed in anaerobic digestion production and denitrification effect. As a result, solubilization was increased by increasing treatment time of electrolysis and current density, also showed to be 9.02% with 10 mA/cm2 of current density in 4 mm electrode distance. Based on the results of BMP test used the above experiment, methane production was 0.49 L CH4/g VS, and increased by 88.4% compared with control groups. As for the results of denitrification using the sewage sludge treated with the same conditions, denitrification rate appeared $19.2mg\;NO_3{^{-}}N/g\;MLVSS{\cdot}hr$, and through the sewage sludge treated with electrolysis, it can be applied to anaerobic digestion and denitrification process by increasing biodegradation.
