Background Composting is used as an environment-friendly and low-cost resource treatment technology for organic wastes (such as sludge, livestock manure, agricultural wastes and the like), and is widely applied to the field of tectorial membrane fermentation. In the composting fermentation process, sufficient and uniform oxygen supply is an important condition for guaranteeing the normal metabolism of aerobic microorganisms and improving the fermentation efficiency. However, most aeration modes commonly adopted in the existing composting systems are single-port aeration or planar aeration structures, and in the practical operation, the aeration structures are difficult to uniformly convey air to various areas of the composting materials. Because the compost material has the characteristics of large stacking thickness, compact structure and the like, the diffusion of oxygen in the material is limited, and an anoxic environment is easy to form in a local area. The anaerobic condition not only can cause the generation of anaerobic byproducts, but also can inhibit the growth and propagation of aerobic bacteria, thereby prolonging the fermentation period, reducing the degradation rate of organic matters, and finally making the composting fermentation efficiency and the fermentation quality difficult to be effectively improved.
