Sealed Fermentation

Sealed fermentation of sheep manure is a common method. Before fermentation, dry sheep manure should be exposed to sunlight for one day to eliminate insects and bacteria. Then, place the dried sheep manure in containers such as plastic buckets or cylinders, and add an appropriate amount of water, ensuring the moisture content is maintained at around 50-60%;

Maintain the sheep manure in the container at 80%. In the fermentation method, seal the container with a lid and place it in a location exposed to direct sunlight. The fermentation process typically takes about three months to complete.

Bury and ferment

R1: "入坑" must be translated as "start"  Original: Burial fermentation involves piling sheep manure into a pit, sprinkling an appropriate amount of water to maintain a moisture content of around 60-80%, then covering the composted sheep manure with a layer of soil and placing it in a warm area for fermentation. This process typically takes about 3-6 months to complete. This fermentation method is relatively simple.  Translation:.

Principles of Composting and Fermentation

Aerobic composting fermentation process: Under aerobic conditions, aerobic microorganisms absorb, decompose, and oxidize substances. Through their metabolic activities, microorganisms oxidize a portion of organic matter into simple inorganic compounds, releasing energy required for microbial growth, while synthesizing new cellular materials from another portion of organic matter to ensure normal growth and reproduction of the organisms

In aerobic fermentation, the primary decomposing agents are thermophilic bacterial groups, which oxidize and decompose organic matter in the presence of abundant oxygen molecules while releasing substantial heat, thereby raising the temperature within the tank.

During the fermentation process, the temperature range of 45°C to 70°C can further promote microbial growth and metabolism. Meanwhile, temperatures above 60°C can eliminate harmful substances such as pathogenic bacteria and parasitic eggs in feces, while also balancing the temperature, humidity, and pH levels required for the survival of beneficial bacteria, thereby meeting their living conditions.

With the continuous addition of materials, the microorganisms in the tank continuously reproduce, achieving harmless treatment. The treated clinker can be directly used as fertilizer or as raw material for producing compound organic fertilizers.

Addition of fermentation agents

During the aerobic fermentation process, the addition of microbial consortia can enhance the decomposition rate and efficiency of microorganisms. Complete decomposition typically takes about 10-15 days (specific duration may vary depending on environmental temperature).

Characteristics of Composting Fermentation

1. The microbial strains in compost fermentation, through high temperatures and the balanced state of microorganisms, kill harmful bacteria, insect eggs, and other pests in the compost, effectively inhibiting the regrowth of harmful bacterial populations.

2. Odor removal. Composting fermentation strains can decompose organic substances and organic sulfides that produce foul gases, while inhibiting the growth of decomposing microorganisms and improving the environmental conditions of the site.

3. Rich in nutrients, low cost, and effective.

4. The equipment is easy to install, occupies a small footprint, has a relatively wide range of raw material sources, and requires a short production cycle.
