Description
Technical field
The present invention relates to organic fertilizer technical fields, and in particular to a kind of production using anaerobism biogas residue production solid organic fertilizer
Technique.
Background technique
By years of researches and it was verified that the organic waste generated in people's life and environment, such as: living
Organic matter, agricultural crop straw, forest fallen leaves, the afforestation vegetation sub-elected in rubbish cuts grass, kitchen garbage, fowl and animal excrement etc., most
Real, most effective processing method is that biogas, three kinds of biogas slurry, biogas residue substances will be generated after fermentation using dry-type anaerobic fermentation.Its
In: biogas can be used for fuel gas generation；Water of the biogas slurry after sewage treatment is up to standard, which returns, can be used for producing；And to containing abundant nutrition
How ingredient biogas residue efficiently uses, and is allowed to turn waste into wealth, and maximumlly creating economic benefit, environmental benefit and social benefit is to work as
Preceding a great problem.
In recent years, with the fast development of Chinese society economy, the quickening and living standards of the people of urbanization process
Rapid raising, domestic waste yield increasingly increases.Averagely everyone generates 0.9~1.2kg house refuse daily in China, and
And increased with annual 3%~5% speed.State Ministry of Environmental Protection's publication in 2016 display: 2015, the big or middle city in 246, China
185,640,000 tons of Output of Domestic Waste, including the annual house refuse total amount that generates in the rural area whole nation is about 496,400,000 tons.Both at home and abroad
To the processing of domestic waste, there are mainly three types of methods: landfill, burn and part compost (kitchen garbage and fowl and animal excrement can heaps
Fertilizer).For vast rural area, discussion agenda is mentioned not yet to house refuse centralized processing work.
China is large agricultural country, and gradually accelerates urbanization process, and current problem is: first is that all kinds of crops straw of agricultural
Stalk yield is very high, at least 70% or more does not efficiently use at present, still based on the burn-up of field the edge of a field, causes largely to provide
Source waste and environmental pollution；Second is that being continuously improved, urban and rural environment greening is horizontal, and afforestation vegetation cuts grass and tree deciduous leaf increases year by year；
Third is that aquaculture continues to develop, birds and livestocks faces gradually increase.
Organic matter in these house refuses, kitchen garbage, fowl and animal excrement, agricultural crop straw, forest fallen leaves, greening at present
Vegetation cuts burning or landfill after grass etc. is substantially collected, and not only wastes vast resources, also brings environmental pollution and increases landfill
Land used.
In short, producing biogas, biogas slurry, natural pond if the organic matter of above-mentioned flood tide is all collected as fermentation raw material
Slag can be efficiently used further, not only renewable mass energy, while can not only have been reduced landfill land used but also can solve serious ring
Border pollution problem.
Chinese patent document CN 101774848B (201010011344.4) discloses a kind of biogas residue organic fertilizer and its preparation side

Daily to one defective material of fermentation vat cloth, start to lower and upper to be taken in the side in blend feedstock stockyard using forklift
Expect, and be fed separately to several and support in fermentation vat well, equably the feed end of cloth to pond, raw material enters aerobic from now on
Fermentation procedure；Next day carries out stirring operation by movable upender, can further mix raw material during stirring, simultaneously will
Raw material is mobile to fermentation vat discharge end, and after vacating the feed end length that can meet one day cloth doses needs, begins to the same day
Cloth material process；It moves in circles by this process, until material reaches fermentation vat discharge end.So far the fertile raw material of system completes entirely good
Aerobe fermentation period, aerobic fermentation period are generally 10~15 days.Thus the length of feed end and discharge end is respectively aerobic fermentation
The 1/10~1/15 of pond total length.The number of days of fermentation period is determined according to the ingredient of fermentation raw material and feature, important
Be by it is all enter pond raw material achieve the purpose that complete fermentation is good within the aerobic fermentation period.The moisture content control of material after aerobic fermentation
System is 40%.
The width of fermentation vat is 4-5m, is highly 1.6-2m under normal circumstances.The item number and length of fermentation vat, mainly root
It is determined according to site condition, production capacity and according to the fermentation period that material condition determines.
During aerobic fermentation: being aerated coil pipe (being equipped with intensive orderly venthole on aeration tube circumference) to object from bottom of pond
The sufficient fresh air of material supply, to meet the needs of material aerobic fermentation is to oxygen.
Bottom of pond is aerated the selection of the arrangement of mounting means and pipe upper vent hole of coil pipe, quantity and supply gas pressure, mainly
It is determined according to fabric thickness in material condition (including gas permeability), pond.Because in each stage material of aerobic fermentation to oxygen
Demand is different, and sectional quantitative air supply method is taken on fermentation vat length direction.
