The organic fertilizer production line includes: compost turning machine, crusher, feeder, horizontal mixer, organic fertilizer granulator machine, dryer, cooler, screening machine, weighing and packaging machine. This organic fertilizer production line can be used to produce granular organic fertilizer and powder organic fertilizer. For example, the annual output is 10 million tons of organic fertilizer, and the investment in organic fertilizer production line equipment is about 300,000-450,000. The annual output of organic fertilizer is 80,000-100,000 tons, and the investment in organic fertilizer production line equipment is about 150,000-200,000.
The modern farm livestock and poultry manure treatment process has been greatly improved, such as farm acidification + high-speed filter + biological oxidation tank treatment, designed to separate the solid and liquid of manure and sewage through natural sedimentation, adjust water, add fertilizer components, compost treatment, and adjust the liquid part through the acidification tank And two series of high-speed biological filters for anaerobic and aerobic biological treatment, the sewage enters the biological oxidation tank for further degradation and storage, and farmland irrigation.
The composting treatment method is to degrade the organic matter in the solid manure by microorganisms under the conditions of artificial control of water, carbon-nitrogen ratio and ventilation to make it mineralized, humified and harmless. Composting is mainly divided into aerobic composting and anaerobic composting. At present, it is mainly aerobic composting. The nutrient content of composted manure is more stable, which is more conducive to the absorption of crops, but it can also improve the soil condition. Therefore, farmers, small and medium-sized farms or farms mainly use the organic fertilizer compost turning machine treatment mode.
Add 1kg of organic fertilizer starter to the fermentation material, preferably straw or mushroom residue to adjust the carbon-nitrogen ratio; the material should be stacked at 1.5m~2m, 2m wide and 2~4m long; the starting temperature should be above 15℃; the moisture content of the fermentation material It should be controlled at about 65%; pay attention to proper oxygen supply and accumulation during the fermentation process (when the temperature rises to 75℃ or above, it should be turned over several times), and the heating should be controlled at about 65℃.
