In-depth Analysis of Aerobic Fermentation Technology

In the field of organic fertilizer production, aerobic fermentation technology has become the most mainstream treatment method worldwide due to its maturity, stability, efficiency, and environmental friendliness. Through scientifically controlling microbial activity, this technology transforms organic waste such as crop straw and livestock manure into high-quality organic fertilizer, achieving dual goals of resource recycling and environmental protection. Principle of Aerobic Microbial Conversion The core of aerobic fermentation lies in utilizing the metabolic activities of aerobic microorganisms such as Bacillus and Actinomycetes. Under oxygen-sufficient conditions, these microorganisms can efficiently decompose complex macromolecular substances like proteins, cellulose, and fats in organic raw materials. During decomposition, microorganisms release significant heat through respiration, raising pile temperature to 55-70°C. This creates suitable growth conditions for microorganisms while achieving harmless treatment of raw materials. Temperature control is crucial in this process. Ideal fermentation temperatures not only promote rapid organic matter decomposition but also effectively eliminate pathogens, insect eggs, and weed seeds with eradication rates exceeding 95%. Simultaneously, high-temperature environments facilitate the action of specialized microorganisms like cellulose-decomposing bacteria, accelerating the transformation of difficult-to-degrade materials such as straw.
