Description
Technical field
The present invention relates to a kind of countryside wastes processing and utilization methods.
Background technology
China is large agricultural country, generates a large amount of agriculture and forestry organic waste material every year, wherein in addition to small part is used for returning to the field and system
It makes except compost, largely discards and be incinerated in field, not only waste a large amount of biomass energy, but also cause sternly to environment
It is fewer and fewer due to transport, stacking, pollution and efficiency etc. directly to be made energy fuel burning by heavily contaminated for agriculture and forestry organic waste material
.And China rural area also generates a large amount of house refuse, kitchen garbage, soiled litter and sewage sludge daily, wherein greatly
Part is biodegradable or biological compost, but resource utilization is low；And biogas residue contain the pathogen that is much pernicious to people and
Pathogenic factor, it is also desirable to its further harmless treatment, increase intractability.
If a large amount of agriculture and forestry organic waste materials and garbage utilization that rural area produces can get up, reduce volume, boil down to molding
Fuel improves the calorific value of unit volume, can not only be used for the life fuel of resident or the fuel for heat and generating power, can also burn
Harmful pathogen is thoroughly removed at a high temperature of burning, and other pathogenic factors such as heavy metal factor can burn laggard ash charge in fuel
In cinder, then minute quantity ashes are further processed, then it is much more convenient, solve the pathogen being pernicious to people and pathogenic factor
Thorough process problem realizes the recycling of resource, minimizing and innoxious.
Invention content
In order to solve technological deficiency of the existing technology, the present invention provides a kind of countryside wastes processing and utilization method,
It can solve pollution problem and the problem of resource waste of countryside wastes, realize the recycling of resource, minimizing and harmless
Change.
The present invention is that technical scheme applied to solve the technical problem is as follows：
A kind of countryside wastes processing and utilization method, by agriculture and forestry organic waste material, house refuse, kitchen garbage, rural area sludge, excrement into
Row is mixed to get mixture, and the mixture is fermented, and is collected the biogas that fermentation generates for cooking, heating,
The solidliquid mixture that fermentation generates is separated into biogas slurry and biogas residue, the mixture is added in biogas slurry before fermentation；By the natural pond
Slag is mixed into agriculture and forestry organic waste material, exterior wall rubbish carries out extrusion forming, obtains biogas residue solid fuel.
At 15-25 DEG C, fermentation time is 30-45 days for fermentation temperature control.
The exterior wall rubbish is that rustic home wall peels off rubbish, and containing lime paste, it is powdered to control it.
The extrusion forming temperature control is at 80-120 DEG C.
The agriculture and forestry organic waste material includes stalk, rice husk, edible fungi substrate, leftover pieces, fuel wood, bark, peanut shell, branch bavin, volume
One or more of skin, wood shavings, sawdust；House refuse is one or more of stationery, waste plastics；Kitchen garbage is leftovers
Leftovers foodstuff waste；Rural area sludge is the sludge after rural domestic sewage treatment.
The biogas residue moisture content is controlled as 25% hereinafter, and being crushed to 1cm or less；The agriculture and forestry organic waste material is to shine dry doubling to be crushed to
1cm agriculture and forestry organic waste materials below；The exterior wall rubbish is the powdered rubbish filtered out；The biogas residue, agriculture and forestry organic waste material, exterior wall
The weight ratio of rubbish is：10-12:15-20:1-2.
Since after adopting the above scheme, the present invention in use, makes countryside wastes obtain complete recovery energy,
The economic benefit for increasing countryside wastes, while avoiding environmental pollution, reduces the cost of corresponding industry indirectly.And it will
Fuel is made in combustion in biogas residue, and the lime paste contained in exterior wall rubbish plays desulfidation, can generate fuel combustion
Sulfur dioxide is sloughed, and pollution of the sulfur dioxide to environment is reduced.Further, solid fuel is made convenient for storage and transport.
