Abstract
The present invention relates to the methods that a boar factory discards excrement forming, obtain the pig manure particle that pattern is completed and has some strength by prilling and stoving process；The present invention reduces the discharges of pollutant, improve the resource utilization during pig-breeding.This method scalability is strong, suitable for preparing the product of multiple use, meets the theory of green cultivation.
Description
Technical field
The invention belongs to a kind of aftertreatment technologies of pig manure in pig-breeding technical field more particularly to breeding process.
Background technique
Live pig is the maximum breed variety of animal husbandry, and the specific gravity that the live pig amount of delivering for sale accounts for the national always amount of delivering for sale reaches 92.06%,
China's live pig localization of production is laid out to be formed, and advantage producing region is prominent.With the increase of animal husbandry environmental protection pressure, many livestock and poultry
Field increasingly wishes that fecaluria can decompose in livestock and poultry farm with regard to carrying out consumption completely, avoids waste outlet and leak to cause environment
Harm.
N and P content are higher in pig manure, and the nutrient that can be utilized in excrement accounts for about 70%, as organic fertilizer utility value compared with
It is high.80.1% is organic matter in the dry matter of pig manure, and easy decomposability organic C is 27.3%, the content of hemicellulose and cellulose
Lower, the content of crude fat and lignin is higher.
Granulation is that typically in method used in powder, at present using less in the post-processing of pig factory waste material.Conventional pig
Excrement processing is directly to be thrown on arable land, but cause biggish environmental pollution.In industrialization cultivation and Intensive course of ploughing,
It must solve the problems, such as that high efficiente callback discards excrement using pig factory.In order to make full use of pig-breeding continually to generate in the process
Excrement material, the present invention provides a kind of efficient prilling process, this method is not only simple efficiently, and adapts to different application scene
It needs, makes full use of to turn waste into wealth and provide advantage for further work-up, retrieved through applicant, pig manure is shaped at present
Mode study it is less.
Summary of the invention
In order to solve the above technical problems, the present invention provides the methods that a boar factory discards excrement forming.
The present invention is achieved by the following technical programs.
The present invention provides the method that a boar factory discards excrement forming, step includes：
(1) the swine excrement soaking fermentation 12-36h that will be collected during intensive culture；Dejecta moisture and viscosity are adjusted,
It is granulated it easily；
(2) soft grain granulation：The excrement for adjusting moisture content is directly granulated with soft grain granulation machine,
(3) it dries：The above-mentioned soft granulated fertilizer being granulated into is dried, granulated fertilizer is made；
(4) it sieves：Pig manure will be granulated by screening machine, obtain the suitable particle of partial size.
The mode for adjusting dejecta moisture be the excrement that will have been cleaned add water or be dehydrated make dejecta moisture up to 50~
70% (weight percent)；
The mode for adjusting stool consistency is to add straw after fermenting preceding or fermentation；Or adjust fermentation temperature and time；
Or adjust zymophyte；Or clay such as kaolin or concave convex rod is added
The stoving process is that 1-12h is first air-dried at 0-20 DEG C, then in 40-80 DEG C of heating 1-12h, finally in 90-
200 DEG C of drying 1-12h are basically unchanged granule-morphology after drying；
The purpose of drying is so that organic matter in pig manure particle is gradually carbonized, and keep the pattern of particle, is not crushed.
The pattern, which is basically unchanged, to be referred in the complete pattern conservation rate of particle 90% or more, is not crushed.
The present invention obtains the pig manure particle that pattern is completed and has some strength by prilling and stoving process, should
Particle can be faecal pellet or carbonization or partially carbonized particle, and ingredient is mainly the organic matter carbon ball for including certain impurity；Institute
Charcoal fire fire source can be used as, recycle in ecologic breeding factory as fertilizer, as adsorbent material, being used as preparation work by stating component
Property Carbon Materials.The adjustable different faecal pellets of partial size can be obtained by being granulated.The present invention reduces the discharges of pollutant, improve life
Resource utilization in pig breeding process.

2, then natural drying dehydration；Make moisture content up to 15% (weight percent), stirring-granulating；
3, it is granulated by the pig manure for adjusting moisture content and viscosity, with soft grain granulation machine,
4, by the above-mentioned soft particle of the pig manure being granulated into 20 DEG C of drying 1h, then in 80 DEG C of heating 2h, then 90 DEG C are warming up to
Heat 4h；Pig manure active carbon particle is obtained after screening, can be used for the absorption of pig factory heavy metal ions in sewage and organic matter.
Embodiment 3：Make barbecue charcoal
1, the swine excrement soaking fermentation 12h collected, adjusting fermentation temperature are 40h, fermentation time 12h；
2, then manually dehydrated；Make moisture content up to 55% (weight percent), carries out low temperature drying granulation；
3, the soft particle of the above-mentioned pig manure being granulated into is subjected to outdoor (about 30 DEG C of temperature) and dries 8h, then heated at 40 DEG C
