Problems solved by technology

[0005] In the prior art, many farmers do not have the awareness in this regard, and they dispose of the excrement and urine of livestock and poultry at will, resulting in a poor environment near the breeding ground; relatively large farms usually have the awareness of this aspect, and there are cooperations with organic fertilizer manufacturers Cooperation, but there are very big problems in the actual processing:
However, in reality, there is still the problem that the accumulation of biogas residues and biogas fluids cannot be dealt with, and direct discharge will still cause environmental pollution
According to the research of those skilled in the art, this type of biogas residue and biogas slurry can still be used as raw material for organic fertilizer, but it still has the problem of high water content, and the situation has returned to the aforementioned situation

Embodiment

[0038] The method for rapidly reducing the moisture content in livestock and poultry excrement and urine used in the pretreatment process of organic fertilizer production comprises the following steps:

[0039] (1) Establish a treatment platform locally on the farm; the treatment platform is preferably a fermentation tank, its main function is fermentation, so that the water can be evaporated by fermentation and temperature rise, and it can be set lower than the ground in specific settings (digging pits on the ground), It can also be set higher than the ground (build a pool on the ground), without affecting the use effect, and to a certain extent, it can realize the immediate treatment of livestock and poultry excrement and urine, which greatly saves transportation costs;

[0040] (2) Prepare fermentation bedding, the raw materials of which include at least one of sawdust, rice husk, straw, fungus residue or dry cow dung after dry-wet separation, and lay the fermentation beddin...

Abstract

The invention discloses a method and a system for quickly reducing moisture content in feces and urine from animals and poultry in a pretreatment process of organic fertilizer production. The method comprises the following steps: (1) building a processing platform; (2) paving fermentation padding inside the processing platform; (3) adding feces and urine from animals and poultry to the fermentation padding, adding proper fermented culture and then evenly mixing to form a material pile; (4) adding the feces and urine from animals and poultry after the temperature of the material pile ascends to over 50 DEG C, evenly mixing, carrying out moisture evaporation by fermentation and temperature rise, and repeating; (5) detecting the nutrient ratio of the material pile and selecting subsequent execution steps at a fixed period. A microbial fermentation technique is skillfully introduced into the pretreatment process of organic fertilizer production, and the moisture is evaporated by using high temperature generated by fermentation, so that the moisture content of the feces and urine from animals and poultry is reduced, not only is transportation facilitated, but also the raw materials can be directly used in subsequent production, the time cost and the equipment cost for organic fertilizer production are saved, and the method and the system have landmark positive significance on improvement of production efficiency and increase of economic benefits.

Description

technical field [0001] The invention relates to the field of pretreatment of organic fertilizer production by using feces, in particular to a method and system for rapidly reducing the water content in livestock and poultry manure used in the pretreatment process of organic fertilizer production. Background technique [0002] Organic fertilizer, commonly known as farmyard manure, refers to a slow-acting fertilizer that contains a large amount of biological matter, animal and plant residues, excrement, biological waste and other substances. Organic fertilizers not only contain essential macroelements and trace elements for plants, but also rich organic nutrients, which can not only provide comprehensive nutrition for crops, but also have long fertilizer effects, which can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and Biological activity is the main nutrient for green food production. [0003] Livesto...
