| Abstract: | The alcohol wastewater effluent from anaerobic digester has the COD concentration of 6500 mg/L, with low biodegradability. Iron chipping micro-electrolysis process was used as pre-treatment to improve the biodegradability of wastewater. The result shows that iron chipping micro-electrolysis process is successful in removing refractory organics and improving biodegradability of wastewater, and it removes 50% of the COD concentration and raises the B/C ratio from 0.33 to 0.55. |
