The fermentation principle of producing organic fertilizer from livestock and poultry manure and kitchen waste mainly relies on the biodegradation of microorganisms to convert the organic substances in organic waste into stable organic fertilizer. The specific process is as follows:

Microbial decomposition: The fermentation process is dominated by aerobic and anaerobic microorganisms, mainly including bacteria, fungi, and actinomycetes. They produce carbon dioxide, water, and heat by decomposing organic compounds in raw materials such as proteins, fats, sugars, etc.

Aerobic fermentation: In an aerobic environment, aerobic bacteria mainly participate in the decomposition of organic matter, generating carbon dioxide, water, heat, and organic acids. This process increases the temperature (usually reaching 50-70 ° C), which helps to kill pathogenic microorganisms and weed seeds.

Anaerobic fermentation: Under anaerobic conditions, anaerobic microorganisms decompose organic waste to produce gases such as methane and hydrogen sulfide. It mainly occurs in enclosed composting ponds or reactors.

Thermodynamic changes: During the fermentation process, the activity of microorganisms generates a large amount of heat, causing the temperature of the pile to rise. This helps accelerate the decomposition of organic matter while inhibiting harmful microorganisms and bacteria.

Nutrient conversion: Elements such as nitrogen, phosphorus, and potassium are metabolized by microorganisms into forms that plants can absorb, forming nutrient rich organic fertilizers.

Degradation of harmful substances: Through high temperature and appropriate fermentation time, most harmful substances such as pathogens, parasite eggs, and drug residues will be effectively degraded or transformed during the fermentation process.

In summary, the fermentation principle of organic fertilizers from livestock and poultry manure and kitchen waste mainly relies on the degradation of microorganisms. After aerobic and anaerobic fermentation, they are converted into organic fertilizers that can be used in agriculture, with multiple effects such as improving soil, providing nutrition, and environmental protection.
