Embodiment 1

[0036] Such as figure 1 Shown, a kind of method utilizing pig manure to produce organic fertilizer comprises the steps:

[0037] (1) Mixing: Mix pig manure with a water content of 70% and rice bran, the ratio is 900kg by weight of pig manure, 100kg by weight of rice bran, add 0.18kg of EM mixed bacteria agent, and then add plant ash to mix and adjust evenly Water content, so that the water content of the mixed material is 50%.

[0038](2) Primary fermentation: Transport the mixed material obtained in step (1) to the fermentation workshop with a forklift and pile it up in stacks. The width of each stack is 1.8m and the height is 1.2m. Carry out aerobic fermentation. , the fermentation time is 15 days, and the pile is turned every 2 days with a turning machine, and the natural oxygenation is used during the turning process. The moisture content of the material after one fermentation is about 45%. Aerobic fermentation is the use of external enzymes of aerobic microorganisms to...

Embodiment 2

[0043] Such as figure 1 Shown, a kind of method utilizing pig manure to produce organic fertilizer is characterized in that comprising the steps:

[0044] (1) Mixing: Mix pig manure with a water content of 80% and rice bran. The ratio is 1100kg by weight of pig manure and 130kg by weight of rice bran. Add 0.22kg of EM mixed bacteria agent, and then add plant ash to mix and adjust evenly Moisture content, so that the water content of the mixed material is 60%;

[0045] (2) Primary fermentation: Transport the mixed material obtained in step (1) to the fermentation workshop with a forklift and stack it into stacks. The width of each stack is 1.8m and the height is 1.6m. The time is 17 days, and the pile is turned once every 2 days with a turner;

[0046] (3) Secondary fermentation: Pile the products obtained in step (2) into piles for anaerobic fermentation, and the fermentation time is 7 days;

[0047] (4) Moisture adjustment: add the product obtained in step (3) to plant ash...

Embodiment 3

[0050] Such as figure 1 Shown, a kind of method utilizing pig manure to produce organic fertilizer comprises the steps:

[0051] (1) Mixing: Mix pig manure with a water content of 75% and rice bran. The ratio is 1000kg by weight of pig manure and 150kg by weight of rice bran. Add 0.2kg of EM mixed bacteria agent, and then add plant ash to mix evenly. Moisture content, so that the water content of the mixed material is 55%.

[0052] (2) Primary fermentation: Transport the mixed material obtained in step (1) to the fermentation workshop with a forklift and pile it up in stacks. The width of each stack is 1.8m and the height is 1.4m. Carry out aerobic fermentation and ferment in summer , the fermentation time is 20 days, and the pile is turned every 2 days with a turning machine.

[0053] (3) Secondary fermentation: the products obtained in step (2) are piled up with a forklift for anaerobic fermentation, and the fermentation time is 9 days.

[0054] (4) Moisture adjustment: T...

Abstract

The invention relates to a method for producing organic fertilizer by using pig manures. After pig manures are subjected to dry-wet separation, the pig manures are subjected to dynamic-continuous high-temperature fermentation by using microorganisms, and in the process of fermentation, substances which are easily decomposed and easily produce odor in raw materials are decomposed and transformed by using the microorganisms, and the purposes of killing pathogens, eliminating odor, reducing the water content, lowering the volume and weight, and enhancing the available nutrient content are achieved by using the high temperature produced in the process of decomposition.

Description

technical field [0001] The invention relates to an organic fertilizer production process, in particular to a method for producing organic fertilizer by using pig manure. Background technique [0002] Organic fertilizers are generally processed from animal and plant wastes and plant residues to eliminate toxic and harmful substances and contain a lot of beneficial substances. However, the production process of organic fertilizers is relatively simple now, and the efficacy of organic fertilizers is poor, making it difficult for crops to absorb them. The poor efficacy of pure organic fertilizers is the general nature of organic fertilizers. The nutrient content is low, the fertilizer effect is slow but the fertilizer effect is long, and more advanced technologies cannot fundamentally change this state. At present, organic fertilizer processing is greatly affected by the natural environment, the fermentation cycle is long, the output is relatively low, the degree of automation i...
