Aerobic composting is an effective means for treating solid waste, and has good application prospect in the aspects of solid waste volume reduction and resource utilization. Composting means that microorganisms take advantage of oxygen and organic matters to perform aerobic respiration to form nutrient substances. The growth and metabolism of microorganisms play a key role in aerobic composting, requiring aeration to achieve oxygen demand. However, aeration and heat can cause the evaporation of large amounts of moisture, resulting in a rapid drop in moisture content. The appropriate water content in the composting process is 50% -60%, when the water content is too low, the compost is hardened, the decomposition of organic matters is delayed, the composting time is increased, and the fertility is reduced.
The aeration and the water content are in conflict with each other because the supplementary water is a necessary condition for keeping the compost at the proper water content, but the aeration of the compost can cause the air of the compost to be not circulated, thereby influencing the mass transfer effect of oxygen in the compost. The air distribution in the compost is not balanced, and the local anaerobic condition is more serious. The anaerobic environment can inhibit the aerobic composting rate and even lead to the collapse of the aerobic composting system and simultaneously generate malodorous gas such as H2S, volatile fatty acid, which limits the application of aerobic composting.
