The influence of aeration process on the humification transformation of solid substances in cow manure

Three groups of aerobic composting experiments using cow manure solids as raw materials were conducted in a 90 L laboratory reactor. Group CA_1.5 was subjected to continuous aeration at a rate of 1.5 L/min. Group CA_3 was aerated continuously at a rate of 3 liters per minute. Group IA_3 was subjected to intermittent aeration at a rate of 3 liters per minute, with 30 minutes of aeration followed by 30 minutes of cessation. By studying the effects of different aeration processes on the transformation of compost humus, the composting process was optimized.
