A pilot experiment was carried out to investigate effects of different aeration rates (A: 0.01, B: 0.02, C: 0.03, and D: 0.04 m–3·min–1) on decomposition of organic waste and enzymatic activities during the composting process in a 100L bioreactor. Compared with lower aeration rates (A and B), higher aeration rates (C and D) could effectively improve the composting process in terms of promoting temperature and oxygen consumption, lowering C/N ratio, and significantly increasing all enzyme activities including those for protease, urease, dehydrogenase, β-glucosidase, and cellulase during the composting period.
