Problems solved by technology

[0003] Composting fermentation is inevitably used in the existing technology of using poultry and livestock manure to produce organic fertilizers, and the existing composting fermentation process needs to be turned over at certain intervals. Even so, the uniformity of fermentation is not easy to control , the effect of composting fermentation is still not ideal, it takes a long time, and the controllability is poor

Embodiment 1

[0026] The method for producing organic fertilizer from poultry and livestock manure of the present embodiment may further comprise the steps:

[0027] 1) Pretreatment: add 3% quicklime to the raw poultry manure, and after stacking for 2 hours, adjust the moisture content of the mixed material below 20%;

[0028] 2) Primary fermentation: Put the mixed material in the tank, and the mixed material is spread in multi-layers from the inside to the outside in the tank. Each layer is equipped with an independent temperature control device, replenish water to the mixed material and start stirring , wherein the water used is the water separated from the mixed material in step 1), the water content of the mixed material is controlled at 55%-65%, and the stirring is started intermittently for a fermentation;

[0029] 3) Secondary fermentation: adjust the moisture content of the mixed material at 40%-45%, stack it, cover it with thermal insulation film, and carry out secondary fermentati...

Embodiment 3

[0038] The method for producing organic fertilizer from poultry and livestock manure of the present embodiment may further comprise the steps:

[0039] 1) Pretreatment: add 5% quicklime to the raw poultry manure, and after stacking for 2.5 hours, adjust the moisture content of the mixed material below 20%;

[0040] 2) Primary fermentation: Put the mixed material in the tank, and the mixed material is spread in multi-layers from the inside to the outside in the tank. Each layer is equipped with an independent temperature control device, replenish water to the mixed material and start stirring , wherein the water used is the water separated from the mixed material in step 1), the water content of the mixed material is controlled at 55%-65%, and the stirring is started intermittently for a fermentation;

[0041] 3) Secondary fermentation: adjust the moisture content of the mixed material at 40%-45%, stack it, cover it with thermal insulation film, and carry out secondary fermenta...

Abstract

The invention relates to a method for producing an organic fertilizer from feces of livestock and poultry, and belongs to the technical field of organic fertilizer processing. The method is characterized by comprising the following steps: firstly, pretreating the feces of livestock and poultry by using quicklime, reducing the water content at first, then putting the feces into a self-made tank, supplementing water for primary fermentation, and then carrying out subsequent secondary fermentation. According to the present invention, the multi-layer and multi-chamber fermentation manner is performed by using a separation plate separation structure, such that the uniformity of the material is easily achieved so as to avoid the fermentation site with the light outer part and the heavy inner part, the energy source can be saved by using the heat generated inside the composting fermentation, and most importantly, the self-made device and the process method are combined, compared with artificial composting fermentation in the prior art, the method is high in automation degree, high in composting efficiency and more controllable in fermentation conditions.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer processing, in particular to a method for producing organic fertilizer from poultry manure. Background technique [0002] With the development of the breeding industry, poultry and livestock manure pollution has become an urgent problem to be solved. In order to solve this pollution problem and fully realize energy utilization, it has become a trend to use poultry manure as raw material to produce organic fertilizers and increase soil organic matter content. [0003] Composting fermentation is inevitably used in the existing technology of using poultry and livestock manure to produce organic fertilizers, and the existing composting fermentation process needs to be turned over at certain intervals. Even so, the uniformity of fermentation is not easy to control However, the effect of composting fermentation is still not ideal, it takes a long time and the controllability is poor. Conte...
