This study was carried out for 30 days in aeration type and agitation type reactor to characterize organic matter decomposition and ammonia volatilization during the liquid composting of pig slurry, and organic matter and nitrogen removal rate through mass balance analysis was analyzed. In the aeration type reactor, the pH increased from 7.0 to 9.13, and TS 34.5%, VS 33.4%, BOD<SUB>5</SUB> 71.2%, COD<SUB>Cr</SUB> 62.3% and TOC 83.2% were removed. In addition, 44.6% of TN and 65.0% of NH₄<SUP>+</SUP><SUB>-</SUB>N were removed. In the agitation type reactor, the pH increased from 7.0 to 8.10, and the removal rates of TS 0.9%, VS 0.5%, COD<SUB>Cr</SUB> 27.5%, BOD<SUB>5</SUB> 28.9% and TOC 41.3% were obtained. And TN and NH₄<SUP>+</SUP><SUB>-</SUB>N showed removal rate of 25.3% and 29.2%, respectively. The first order kinetics constant related to BOD<SUB>5</SUB> degradation was -0.039 day<SUP>-1</SUP> for aerobic liquid composting and -0.013 day<SUP>-1</SUP> for agitated reactor. Nitrogen loss in aerobic liquid composting was about 2.3 times higher than that of agitated reactor, whereas FAN/TAN in aerobic liquid composting was about 7.9 times higher than that of agitation type reactor. Therefore, despite the low FAN/TAN in the agitation type reactor, the nitrogen loss rate was relatively high.
