Description
Technical field
The invention belongs to poultry excrement and urine disposal and utilize field, recycle particularly to after a kind of cattle manure reprocessing
System, more specifically, relate to a kind of reprocess with cattle manure for Raw material processing after the solid that obtains for cattle bed
Bedding and padding, liquid are for the system of crop irrigation.
Background technology
Cattle manure, as a kind of animality organic fertilizer, is the resource of a kind of preciousness, and cattle feed intake is big, every day institute
The fecaluria discharged is more than other domestic animals, and an Adult Bovine, Fecal wastes amplitude is 28.4-48.1kg the most round the clock, often
Voided volume amplitude is 6.5-14.1kg round the clock, and substantial amounts of cattle manure urinates not only contaminated air and water source, and occupies
Large stretch of soil, is the most at home and abroad mainly used in compost and prepares biogas in the processing method of cattle manure.
Using the processing method of compost, cattle manure processes through biochemical processing technique and makes green organic manure, but
Being that composition is similar to pig manure due to cattle manure quality consolidation, in excrement, water content is high, and aeration is poor, decomposes slowly,
Fermentation temperature is low, and fertilizer efficiency is slow, therefore practising cattle manure is called " cold manure ".
Use the simple processing method preparing biogas, as directly a large amount of cattle manures being placed in anaerobic fermentation equipment
Fermentation is to produce substantial amounts of biogas, and after fermentation, the processing method of usual remaining residue is difficult to satisfactory.
For solving the problems referred to above, occur in that various solution, such as, Chinese patent literature at present
Disclosing a kind of novel cattle excrement and urine treating system [patent No. ZL201320634426.3], it is by manure lagoon, solid
Liquid separator, exsiccator, pulverizer, methane-generating pit form, and utilize excrement dirt flushing pump that cattle manure be will pass through raw material
Conveying pipe enters described solid-liquid separating machine and carries out solid-liquid separation, and isolated solid-state cattle manure is just by solid-liquid separating machine
Discharging opening output, enter exsiccator be dried process, dried cattle manure just through crushing system process
Becoming cattle bed padding, isolated liquid is located at the methane-generating pit of underground by separating the entrance of liquid outlet tube.
The isolated liquid of technique scheme achieves zero-emission, will not to environment, but its
There are at least three point defects: 1, the highest to the utilization rate of feces, do not carry out effective anaerobic fermentation flow process also
And the biogas just for biogas slurry generation utilizes, the biogas therefore produced is very limited, particularly to generation
The utilization of biogas be short of especially, the recycling system of a circulation can not be formed, i.e. utilize feces from
The biogas that body produces is supplied in the heat drying of solid-state feces；2, due to biogas from anaerobic ferment devices output time,
Particularly when middle temperature or hot fermentation, carry substantial amounts of H2S, owing to also having substantial amounts of water vapour in biogas
Exist, water and the H in biogas2S acts on jointly, accelerates the corrosion of metallic conduit, valve and effusion meter and blocks up
Plug.It addition, H2SO is generated after S burning2, it is combined into sulfurous acid with the steam in combustion product, makes equipment
Metal surface produces corrosion, and also can cause the pollution to atmospheric environment, affects health.Therefore,
Before using biogas, it is necessary to remove H therein2S；3, the fermentation of the biogas slurry in methane-generating pit utilizes one with biogas slurry
Body, carries significant component of biogas when needs biogas slurry is irrigated in biogas slurry, because these biogas are not carried out
Environmental protection processes thus can produce serious penetrating odor and environment is had pollution.In sum, originally
Therefore case gives birth to.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that after a kind of cattle manure reprocessing, reclaim profit
With, its reprocess with cattle manure for Raw material processing after solid of obtaining for cattle bed padding liquid for crop irrigation
System.
The present invention solves problem and the technical scheme is that
