Embodiment 1

[0029] The preparation method of high-efficiency bio-organic fertilizer comprises the following steps:

[0030] (1) Biogas residue production: put the collected pig manure into the sewage collection tank, and add 2 times the weight of treated water to soak the manure for 12 hours, add an acid-base regulator, and adjust the pH value to 6; then Transfer to the microbial pretreatment tank and add the activated microbial bacterial liquid, add an acid-base regulator, adjust the pH value to 5 to obtain pretreated mixed feces; the added amount of the microbial bacterial liquid is 1 / 1000 of the volume of the pretreated mixed feces ; After the pretreatment mixed manure is processed, it is transferred to the fermentation biogas tank for fermentation. The fermentation temperature is 28 °C and the fermentation time is 48 hours. The remaining fermentation product is filtered and pressed until the moisture content is 40% to obtain biogas residue;

[0031] (2) Secondary sedimentation: impor...

Embodiment 2

[0047] The preparation method of high-efficiency bio-organic fertilizer comprises the following steps:

[0048] (1) Biogas residue production: put the collected pig manure in the sewage collection tank, and add 3 times the weight of treated water to soak the manure for 18 hours, add an acid-base regulator, and adjust the pH value to 8; then Transfer to the microbial pretreatment tank and add the activated microbial bacterial liquid, add an acid-base regulator, adjust the pH value to 7 to obtain pretreated mixed feces; the amount of microbial bacterial liquid added is 1 / 1500 of the volume of the pretreated mixed feces ;After the pretreatment mixed manure is processed, it is transferred to the fermentation biogas tank for fermentation. The fermentation temperature is 32°C and the fermentation time is 50h. The remaining fermentation products are filtered and pressed until the moisture content is 50% to obtain biogas residue;

Embodiment 3

[0065] The preparation method of high-efficiency bio-organic fertilizer comprises the following steps:

[0066] (1) Biogas residue production: put the collected pig manure in the sewage collection tank, and add 2.5 times the weight of treated water to soak the manure for 14 hours, add an acid-base regulator, and adjust the pH value to 7; then Transfer to the microbial pretreatment tank and add the activated microbial bacterial liquid, add an acid-base regulator, adjust the pH value to 6 to obtain pretreated mixed feces; the amount of the microbial bacterial liquid added is 1 / 1200 of the volume of the pretreated mixed feces ; After the pretreatment mixed manure is processed, it is transferred to the fermentation biogas tank for fermentation. The fermentation temperature is 30°C and the fermentation time is 49 hours. The remaining fermentation product is filtered and pressed until the moisture content is 45% to obtain biogas residue;

Abstract

The invention relates to the technical field of fertilizer processing and in particular relates to a manufacturing method of an efficient biological organic fertilizer. The manufacturing method comprises the following three steps of: (1) biogas residue manufacturing; (2) secondary settlement; and (3) sterilizing and packaging. In the manufacturing process, pig manure is soaked by adopting treatment water, so that foul smell of the pig manure is effectively reduced, and meanwhile, in the treatment process, self-made activated sludge can be adopted to treat the pig manure, so that peculiar smell of the pig manure can be effectively removed, and the BOD content in the pig manure sewage can be effectively reduced. By using a plant flocculant from independent research and development to treat the wastewater, secondary pollution is not caused while the flocculation effect in the wastewater is enhanced. By adopting a synergic additive from independent research and development, the content of microelements in the organic fertilizer is effectively increased.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of fertilizer processing, in particular to a preparation method of high-efficiency bio-organic fertilizer. [0003] 【Background technique】 [0004] In the breeding industry of Bamaxiang pigs, pig manure is the main substance that causes environmental pollution. Pig manure has a strong smell and contains harmful pathogenic bacteria. Therefore, the problem of manure disposal is a common problem that large-scale pig farms must face. In the process of pig manure, the most economical and effective method is to produce pig manure into organic fertilizer for resource recycling. However, at present, most pig farms are too extensive in processing pig manure. Many farmers want to reduce the amount of organic fertilizer. The production cost, the conventional technical method is to use the pig manure directly in the crops after composting and retting. Although the pig manure has a strong taste, it is rich in fer...
