Composting treatment is a process of degrading organic matter in solid feces through microbial action under the condition of artificial control of water, carbon nitrogen ratio and ventilation, so as to make it mineralized, humic and harmless. Compost is mainly divided into aerobic compost and anaerobic compost. At present, aerobic compost is mainly used. After composting, the nutrient composition of feces is more stable, more conducive to crop absorption, and can improve soil conditions. Therefore, this organic fertilizer equipment treatment mode is mostly used by farmers, small and medium-sized farms or farms.
Add 1kg organic fertilizer starter to the fermentation product, and it is best to add straw or mushroom residue to adjust the carbon nitrogen ratio; The stacking of materials is 1.5m ~ 2m, 2m wide and more than 2 ~ 4m long; The starting temperature should be above 15 ℃; The moisture of fermentation materials should be controlled at about 65%; During the fermentation process, pay attention to proper oxygen supply and pile turning (several times when the temperature rises to 75 ℃ or above), and control the temperature rise at about 65 ℃.
After the harmless treatment of organic fertilizer equipment, a variety of components in feces can be transformed into nutrients needed for plant growth and become useful resources. The contents of nitrogen and phosphorus in feces are related to the metabolism of feed nutrients, and the amount of wastewater is affected by the factors of production and management. Therefore, the source, influencing factors, utilization value and treatment cost of feces should be comprehensively considered when using organic fertilizer equipment to treat organic fertilizer. It should be based on source emission reduction, prevention first, combination of planting and breeding, utilization priority, adjusting measures to local conditions, reasonable selection Choose appropriate treatment and utilization methods based on comprehensive consideration and overall consideration.
