摘要：To investigate purification mechanism of the aerobic treatment of high-concentration swine waste, behavior of several components in swine waste on aeration was examined by the batch process and following results were obtained. (1) When COD value is conspicuously reduced, total solid, ignition loss, protein, and saccharides are markedly removed from the waste. (2) Lower fatty acids are removed completely by 24-hr aeration. This removal caused early high reduction of BOD. (3) Hexosamine, one of the components of protein-polysaccharide complex, was removed slowly four days. (4) As the purification progressed, substances not precipitated by standing but precipitated by centrifugation at 10000 rpm for 15 min were removed. (5) Substances responsible for COD remaining in the supernatant of the treated waste might be soluble components mainly composed of saccharides, pigments, and NO-2
