초록

Liquid fertilization of pig manure slurry is very useful treatment method to recycle organic waste matter as a valuable fertilizer. The solids precipitate and accumulated at the bottom of liquid fertilization tank. The content of nitrogen and phosphate are higher in sediment than pig manure slurry. The pH of sediment was 7.53. S-COD/T-COD ratio of pig manure slurry and sediment were 0.477, 0.29, respectively. The moisture content of sediment of pig manure slurry and sediment were 80.45~83.82%, 97%, respectively. The content of organic matter of sediment was 8.79~10.56%. The content of nitrogen and phosphate of sediment and pig manure slurry were 9,000~11,100 mg/L, 9,100~11,100 mg/L, respectively. The particle size of pig manure slurry was distributed from 2 mm to 0.125 mm. On the other hand. the particle size of sediment was under 0.125 mm.
