Description

Technical Field

[0001] The utility model relates to the field of treating solid organic waste by microbial method. Specifically, the utility model relates to a small-scale simulated fermentation system for aerobic composting. Background Art

[0002] Aerobic fermentation technology is an effective way to realize the resource utilization of solid organic waste. Perishable garbage such as kitchen waste and tail vegetables can be finally converted into compost products such as humus through the transformation of microorganisms. The compost products can be used as fertilizers, which have the advantages of improving soil structure, maintaining soil physical and chemical properties, and regulating soil microbial balance.

[0003] In the aerobic fermentation technology of solid organic waste, microorganisms are the core of aerobic composting technology and the key driving factor for compost decomposition. Adding exogenous microbial inoculants during the composting process can promote the diversity of microbial communities and stimulate the proliferation of beneficial bacteria.

[0004] During the aerobic composting process, exogenous compound microbial inoculants are often added to improve composting and promote maturity. The development and compounding of microbial inoculants are mostly carried out under laboratory conditions, and there is a large difference between laboratory conditions and actual application environments. If microbial inoculant compounding is carried out in the actual composting environment, the accuracy of the compound microbial inoculant can be improved. However, if the volume of the compost pile is too small, the temperature loss is relatively fast, and it is difficult to achieve natural temperature rise to complete the composting process. Therefore, the actual composting process generally has a relatively large compost pile. This large-volume composting requires a large amount of microbial inoculants for repeated experiments, is difficult to precisely control reaction conditions, increases the cost of microbial input, and is difficult to conduct batch experiments, which is not conducive to the fine research of process parameters and the development of microbial inoculants, thus limiting the development of microbial inoculants to improve the aerobic composting process. Moreover, the leachate generated during the aerobic composting process is not collected and discharged in time, which is likely to form an anaerobic area and is not conducive to the fermentation process.

[0005] Therefore, there is an urgent need to provide a small-scale simulated fermentation system that can carry out small-pile fermentation and is convenient for timely collection of leachate. Summary of the Invention
