Description
Technical field
The present invention relates to a kind of organic solid waste high-temperature aerobic fermentation processing methods.More specifically：It is related in processing procedure
In pass through simple batch mixing state modulator, unique pile Reactor structure, aeration pattern, screening control model, covering waterproof
Under breathable fabric environment, the efficient of target material, emission reduction processing are realized；Without turning, realize similar with turning
Effect；And realizing one kind of the regulation and control of practical residence time under the conditions of different compost materials, Various Seasonal, novel to cover waterproof saturating
Gas fabric compost method.
Background technology
Solid waste is the mankind generated during production and life activity it is general no longer there is original value and by
The solid-state or semisolid substance of discarding can be divided into organic solid waste, two class of inoganic solids waste, wherein organic solid by composition
Waste can be divided into 7 kinds of fundamental types again：1. sludge；2. animal wastes；3. crop residues；4. food production waste；5. work
Industry organic waste；6. timber processes waste；7. house refuse.
It is that yield is huge that organic solid waste, which has first common feature,：By 2012 end of the year whole nation urban wastewater treatment firms
Nearly 30,000,000 tons of sludge annual output (equivalent 80% moisture content)；State Environmental Protection Administration pollutes feelings in 2002 to scale animal and poultry cultivation
Condition investigation result shows that Chinese festiva feces of livestock and poultry amount is about 1,900,000,000 tons；National agricultural crop straw theoretical resources amount is 8.20 within 2009
Hundred million tons (air-drying, water content 15%)；Since nineteen eighty, the domestic waste in China is with the annual growth rate of 8%-10%
Increase, having reached within 2001 1.5 hundred million t, produce are discarded in food production waste, industrial organic wastes, timber processing in addition
It measures huge.
It is that high-temperature aerobic fermentation process is preferably used to handle that organic solid waste, which has second common feature,：For organic solid waste
Harm needs progress minimizing, innoxious, stabilization processes preferably to be adopted since organic matter and moisture are higher in organic solid waste
Individually processing or mixed processing are carried out with high-temperature aerobic fermentation technical finesse.Current all organic solid wastes have high-temperature aerobic fermentation
Case is run, and sludge, animal wastes, agricultural waste material etc. dominate work using high-temperature aerobic fermentation as harmless treatment
Skill.
The principal mode of organic solid waste high-temperature aerobic fermentation processing has slot type, bar buttress formula, container type etc..Earlier industry heap
Fertile system much uses static pile composting technology, because there is such technology investment to save, treatment scale is adjustable, horizontal layout
The features such as flexible, on the U.S., Canada and other places, largely static Windows composting system also remains operational state at present.But due to
A static pile compositing system takes up a large area, climate influences the problems such as big, secondary pollution is not easy to control, the degree of automation is low,
It is restricted in most said conditions application.
Invention content
In view of this, the main purpose of the present invention is to provide a kind of organic solid waste high-temperature aerobic fermentation processing method,
It can solve main problem existing for static pile composting technology.
In order to achieve the above objectives, the technical scheme is that as follows realizing：
A) batch mixing：Organic solid waste is mixed according to a certain percentage with conditioning material to bulk density 0.25-0.75t/m3；
B) cloth：It, later will be among mixed material cloth to pile by tunning oversize cloth to the pile bottom
Layer, then tunning oversize is routed to a pile topmost；
C) overlay film：Upper proofed breathable fabric is covered above pile, and a pile is made to be isolated with atmospheric environment；
D) aerobic fermentation：By being laid on an aerating system for pile bottom in advance according to default monitoring system indication signal to item
Pile intermittent aerating；
E) it sieves：After 7-42 days, proofed breathable fabric is rolled, is moved tunning by method mechanically or manually
It is sieved to adjustable screening system, tunning screenings transports outward recycling, tunning sieve as final products
Upper object returns to cloth material process and participates in next fermentation period.
A kind of the characteristics of organic solid waste high-temperature aerobic fermentation processing method mixing process of the invention be only to organic solid waste and
Conditioning material mixed, control parameter is only bulk density, be different from Traditional compost method to organic solid waste, conditioning material and
Three kinds of materials such as compost product are mixed, and most important control parameter is the indexs such as moisture content, C/N, pH value.
A kind of the characteristics of organic solid waste high-temperature aerobic fermentation processing method cloth process of the invention is to form " sandwich chalk
Power " carton pile Reactor structure, that is, mixed material are in a pile center, and surrounding wraps up tunning oversize；Tunning sieves
Upper object is layed in a pile heap body bottom, and uniform gas distribution effect can be undertaken using its larger porosity；Tunning oversize is laid with
The features such as can utilizing its gap structure and relatively low moisture content at the top of pile heap body, reduces the condensation of proofed breathable fabric lower surface
Water drips the influence to heap body central mixing material.
Above a kind of organic solid waste high-temperature aerobic fermentation processing method pile of the present invention the characteristics of covering proofed breathable fabric
Pile heap body is in supercharging thermal environment when being aeration, also reduces foul smell loss amount in fermentation process.
A kind of the characteristics of organic solid waste high-temperature aerobic fermentation processing method aerobic fermentation process of the invention is aerating system
Start and stop are obtained according to three common result of calculations of parameter such as monitoring system heap temperature, outdoor temperature, aerating system drag overall are preset
It arrives.
A kind of organic solid waste high-temperature aerobic fermentation processing method of the present invention sieves a kind of alternative as turning, aerobic
Fermentation time and tunning screenings ratio are related to material fermentation degree, by adjusting aerobic fermentation time and adjustable knotter screen
The screening ratio of subsystem, realizes the regulation and control of practical residence time under the conditions of different compost materials, Various Seasonal.
The compost product screenings that the present invention obtains is Nutrition Soil, before every pollutant index meets relevant criterion
It puts, can be used as soil agent modifying agent, can be used for urban lawn, flower planting, afforestation, deserta, green barren hill etc.
Aspect also can need to be added a certain amount of synergy inorganic fertilizer according to soil regime and peasant, then be made after sufficiently mixing
Particle uses after packaging.
