Description
Technical field
The present invention relates to a kind of intensive Vegetable area vegetable castoff processing meanss, specifically a kind of light-duty packaged type vegetables
Discarded object anaerobic dry fermentation system and the method using the system anaerobic fermentation, belong to changing rejected material to useful resource technical field.
Background technology
Since implementing the "shopping basket' project from 1988, China's yield of vegetables constantly increases, kind is enriched further, people's people's livelihood
Bioplasm amount is significantly improved.Used as vegetables big country of the world, growing vegetables area reaches more than 300,000,000 mus for China, annual production more than 700,000,000 tons,
No matter from for growing vegetables area or vegetables total output, ranking first in the world.
The root without commodity value, stem, leaf, decayed fruit and waste dish etc. can be produced in vegetables production and process, these claim
For vegetable castoff.China's vegetable castoff yield is larger, produces vegetable castoff 1.0 hundred million～1.5 hundred million t every year according to statistics,
These vegetable castoffs account for the 20-50% of Municipal Solid Waste in China.Vegetable castoff moisture and the content of organic matter are higher, such as
Fruit is arbitrarily stacked, and can cause severe contamination to surrounding environment.And it is rotten arbitrarily to topple over, be piled up in the vegetable castoff of field
It is rotten it is rotten after, air, river, groundwater environment pollution are easily caused, so as to affect vegetables to produce sustainable development.
The biomass type of vegetable castoff is mainly total reducing sugar, protein, fat, hemicellulose, cellulose and lignin,
It is a kind of good biofermentation raw material.The main Land use systems of vegetable castoff are anaerobic fermentation and aerobic compost.In recent years,
Chinese scholars have carried out some researchs to vegetable castoff compost, but for compost, anaerobic digestion process has more
Advantage.Its most important advantage can exactly produce biogas, can be used to generate electricity and heat supply, reduce CO2Discharge, or for vegetable
Dish booth is heated and CO2 gas fertilizer, and postdigestive product can be used as the fertilizer of high-quality through simple process.
In recent years, biogas slurry became the bottleneck of restriction biogas engineering development using difficulty.Dry fermentation is because solving this problem
And enjoy high praise.So-called anaerobic dry fermentation, also known as solid anaerobic fermentation, its reacting quintessence is identical with anaerobism wet fermentation, organic matter
It is divided into liquefaction, acidifying, methane phase three phases through microbiological anaerobic bacterium decomposing and fermenting process；1. in liquefaction stage, anaerobic bacteria
Plant organic matter is digested using enzyme, make solid become water-soluble material；2. acid phase is being produced, then by acid-producing bacteria
Above-mentioned DDGS is generated into acid intermediate；3. in the methane phase stage, finally acid intermediate and material are utilized by methanogen
In other are carbohydrate-modifying for biogas.
Anaerobic dry fermentation handling process is the breakthrough of conventional wet anaerobic fermentation handling process, and the technique has overturned traditional anaerobism
Handling process must allow the mode that raw material and water is thoroughly mixed, but raw material dry substance concentration is brought up to into more than 20%, pass through
Adopt some effective means and complete anaerobic processes, this process is consistent with traditional zymotic Anaerobic Methods in Treating in microenvironment, can
The maximum aerogenesis potential of organic matter is reached, new technology is due to adopting compared with dry matter concentration so energy can be heated with effectively save
Amount, and biogas slurry is not produced, do not result in secondary pollution.The technique is particularly suitable for processing the higher solid waste of solid content
Thing, such as straw from village and feces of livestock and poultry agricultural wastes, city and residents in rural community etc..
Chinese patent literature CN102344232A discloses the side of a kind of feces of livestock and poultry dry fermentation production biogas and fertilizer
Method, solid-state feces of livestock and poultry of the method by dry substance concentration more than 15% is directly entered biogas fermentation device, or and animal dung
Just biogas fermentation device is entered after fermentation residues mixing and produces biogas, fermentation residues are used as to be produced after fertilizer or compost
Fertilizer.Chinese patent literature CN101734961A discloses a kind of processing method of vegetables straw waste, by vegetables
The composition of straw refuse, proterties are studied, there is provided a kind of that vegetables straw waste is concentrated into inoculating complex microorganism of banking up
Fermentation carries out method for innocent treatment, and the method technique is simpler, but process time is long, and efficiency is slow, and what fermentation of banking up was produced has
Evil gaseous contamination environment, and new forms of energy biogas can not be produced, the efficient resource of unrealized discarded object is recycled.It is Chinese special
Sharp document CN102242057A discloses a kind of screw cylinder type dry fermenting apparatus.The method is a kind of achievable lasting input and output material,
The screw cylinder type dry fermenting apparatus of uniform mass transfer, the helical feed of stable aerogenesis.The A of Chinese patent literature CN 105316220 is public
A kind of external stirring garage type anaerobic dry fermentation device is opened, input and output material has been facilitated using garage type structure, passed through after charging inoculation
Autobalance telescopic hydraulic cylinder drives garage type fermentation cabin to incline around fulcrum, makes percolate flow in fermentation solid, realizes
Solution mass-and heat-transfer is uneven, and material is easily acidified problem, while showing, simple structure installation cost is low, energy consumption low advantage.
It can be seen that more, mesh of the domestic scholars for plant's excrement, stalk the like waste dry fermentation device and technique study
The front correlation for not also being specifically designed for vegetable castoff anaerobic dry fermentation apparatus is open to be reported.
The content of the invention
For the deficiencies in the prior art, the present invention provides a kind of light-duty packaged type vegetable castoff anaerobic dry fermentation system
System, the system according to how many designed sizes of vegetable castoff amount, and intensive Vegetable area or dispersion growing vegetables family can be produced
Raw plantation, the process of vegetable for processing discarded object anaerobic fermentation, obtains biogas and organic fertilizer, realizes Vegetable area organic waste goods and materials
Sourceization is utilized, and improves vegetable-growing area environment, improves quality of vegetable, lifts vegetable-growing area land quality.
