초록

The effects of hydrodynamic cavitation solubilization on methane production from waste sludge in anaerobic digestion reactor were researched by the BMP (biochemical methane potential) test and full scale test. As the results of BMP test, the cumulate methane yields before and after solubilization increased from 0.55 to 0.62 L-CH4/g-COD, respectively. The kinetic constant before and after solubilization were 0.0713 and 0.0987 d-1, respectively. As the results of full scale test, SCOD concentration of waste sludge before solubilization was 133~409 mg/L and after solubilization was 302~1,280 mg/L. Biogas production was increased from 6,500 m3/d to 7,100 m3/d by solubilization. At this point, methane yield after solubilization was higher about 1.1 times than before solubilization.
As the hydrodynamic cavitation cycle was increased, the solubilization rate of waste sludge was enhanced and methane production in anaerobic digestion reactor was increased.
