Embodiment 1

[0031] (1) 700kg of poultry manure and 300kg of sawdust are dropped into a composting fermentation mixer and stirred for 3 minutes, so that the carbon-nitrogen ratio of the compost material in the composting fermentation mixer is 25, and the moisture content is 50%;

[0032] (2) 7.5kg contains 1×10 6 CFU / g microbial agent of Bacillus subtilis was added to the compost fermentation mixer mentioned above, the rotor speed was controlled at 25 rpm, and the stirring continued for 1.5 hours. After the temperature of the material rose to 45°C, 7.5 kg containing 1×10 6 CFU / g microbial agent of Bacillus coagulans to the compost fermentation mixer, control the rotor speed at 26 rpm, and continue to stir for 2 hours. After the temperature of the material rises to 60°C, it is cooled by the conveying system, and the fermentation is completed to obtain organic fertilizer. .

Embodiment 2

[0034] (1) Put 700kg of poultry manure, 250kg of stalks and 50kg of sawdust into a composting fermentation mixer and stir for 2 minutes, so that the carbon-nitrogen ratio of the compost material in the composting fermentation mixer is 23, and the moisture content is 45%;

[0035] (2) 7.5kg contains 1×10 9CFU / g microbial agent of Bacillus coagulans was added to the above-mentioned compost fermentation mixer, the rotor speed was controlled at 30 rpm, and the stirring was continued for 1 hour. After the temperature of the material rose to 50°C, 7.5kg containing 1×10 9 CFU / g microbial agent of Bacillus coagulans to the compost fermentation mixer, control the rotor speed at 29 rpm, and continuously stir for 2 to 3 hours. After the temperature of the material rises to 70°C, it is cooled by the conveying system and the fermentation is completed. Organic Fertilizer.

Embodiment 3

[0037] (1) 700kg of poultry manure, 150kg of sawdust and 150kg of wheat stalks are put into a composting fermentation mixer and stirred for 2 minutes, so that the carbon-nitrogen ratio of the compost material in the composting fermentation mixer is 30, and the moisture content is 40%;

[0038] (2) 3.75kg contains 1×10 7 CFU / g Bacillus subtilis and Bacillus coagulans mixed at a ratio of 1:1 are added to the above-mentioned compost fermentation mixer, the rotor speed is controlled at 27 rpm, and the stirring is continued for 1.2 hours. After the temperature of the material rises to 47°C , add again 3.75kg containing 1×10 7 CFU / g Bacillus subtilis and Bacillus coagulans mixed in a ratio of 1:2 to the compost fermentation mixer, control the rotor speed at 27 rpm, and continue to stir for 2.6 hours. After the temperature of the material rises to 65°C, The conveying system is cooled, and the fermentation is completed to obtain organic fertilizer.

Abstract

The invention relates to the field of fertilizer making technologies and discloses a rapid compost fermentation method. The method comprises the following steps: pouring a composting material into a compost fermentation mixer and stirring and mixing, wherein carbon-nitrogen ratio of the composting material is 20-35 and moisture content is 35-50%; adding a microbial agent into the compost fermentation mixer at the weight ratio of the microbial agent to the composting material being 3.75-7.5 kg / t, controlling rotor speed to 25-30 r / m, continuously stirring and fermenting for 1-1.5 h; adding a microbial agent into the compost fermentation mixer once again at the weight ratio of the microbial agent to the composting material being 3.75-7.5 kg / t, controlling rotor speed to 25-30 r / m, continuously stirring and fermenting for 2.0-3 h, and cooling to prepare an organic fertilizer. Fermentation period for each batch is only 3-4 h. by the method of the invention, time is effectively saved. The technology is simple, has strong controllability, has extremely high production efficiency, and can help realize large-scale production effectively.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a composting fermentation method. Background technique [0002] Improper handling of agricultural waste and poultry and livestock manure will cause great pollution to the environment. For example, the treatment of straw is generally burned in the field, causing air pollution; poultry and livestock manure is directly sent to the ground and water without fermentation treatment, which is harmful to soil and water sources. produce pollution. The most effective treatment method for agricultural waste and poultry manure in the prior art is to produce organic fertilizers. [0003] At present, the method of composting and fermenting organic fertilizers by adding human and livestock manure and agricultural waste is to crush the straw first, add water to accumulate it, let it ferment naturally for about 20 days, and then add decomposed human and animal manure and mix evenly ...
