Description
Technical Field
[0001] This utility model relates to the field of solid waste treatment, and in particular to a high-efficiency microbial culture and fermentation device for treating organic solid waste. Background Technology
[0002] With the acceleration of urbanization and the rapid development of industry and agriculture, the amount of organic solid waste generated is increasing daily. If this organic solid waste is not properly treated, it will cause serious environmental pollution and represent a huge waste of resources. Therefore, developing efficient organic solid waste treatment equipment is of vital importance for environmental protection and resource recycling. Microbial culture and fermentation technology has shown great potential in the field of organic solid waste treatment. Through the metabolic action of microorganisms, organic solid waste can be transformed into valuable products such as biofertilizers and bioenergy.
[0003] Traditional organic solid waste treatment equipment often employs simple composting methods or relatively simple fermentation containers. In the early stages of material processing, without specific mechanical assistance, the organic solid waste is mostly piled up manually or with the aid of simple tools. The fermentation process mainly relies on naturally occurring microorganisms, which decompose the organic solid waste naturally under aerobic or anaerobic conditions through open-air piling or simple covering. Turning over the material is usually done occasionally using manual tools to increase air circulation or promote mixing.
[0004] However, traditional treatment methods lack effective material pretreatment and uniform treatment mechanisms during fermentation, resulting in slow fermentation of organic solid waste. Large pieces of organic solid waste are difficult for microorganisms to fully decompose, and microorganisms are unevenly distributed in the material, leading to large differences in local fermentation processes and a significant extension of the overall fermentation cycle. Therefore, a high-efficiency microbial culture and fermentation device for treating organic solid waste is proposed to solve the above problems. Utility Model Content
