Aerobic composting is a biochemical process that relies on the action of obligate and facultative aerobic bacteria to degrade organic matter，The organic material to be piled is mixed with the filling material in a certain proportion，Under proper moisture and ventilation conditions，Allowing microbes to multiply and degrade organic matter，Which creates high temperatures，Kill pathogenic bacteria and weed seeds，To stabilize the organic matter。In the process of aerobic composting, soluble small molecular organic matter in organic waste passes through the cell wall and membrane of microorganisms and is absorbed and utilized by microorganisms。The insoluble macromolecular organic matter is first attached to the outside of the microorganism, decomposed into soluble small molecular substances by extracellular enzymes secreted by the microorganism, and then imported into the cell for use by the microorganism。Through the life activities of microorganisms (synthesis and decomposition process), part of the absorbed organic matter is oxidized into simple inorganic substances, and provides the energy required for activities, and the other part of the organic matter is converted into new cellular substances for microbial proliferation。
