Description
Technical field
The invention belongs to refuse treatment field, be specifically related to a kind of for the pretreated method of kitchen waste compost.
Background technology
Changing food waste, is commonly called as hogwash, is the sanitary waste that resident forms in personal consumption process.In changing food waste, perishable organic content is 40%-50%, mainly comprise rubbish from cooking, catering trade rubbish, food service industry tailing etc., mainly take materials such as starch based, foodstuff fibre class, animal tallow classes as main, there is water ratio high, grease, salt content are high, perishable, fermentation, the feature such as smelly.
In changing food waste, perishable organism moisture and fat content are high, if burn and can greatly reduce the heat energy utilization burning with other domestic garbage mixing, while lipid material wherein becomes the important factor that produces dioxin under the catalytic condition of heavy metal; Landfill disposal can produce a large amount of biogas and percolate, and environment is caused to secondary pollution, and therefore current perishable organism is taked biological treatment mostly.
Compost is the most ancient technology of garbage disposal of China, the technique of composting technology is fairly simple, be suitable for the refuse treatment that perishable organic content is higher, and the waste that stone in rubbish, metal, glass, plastics etc. can not be decomposed by microorganism must out otherwise processed of go-no-go.When compost, to guarantee that organic fertilizer product is up to state standards, just fresh rubbish first must be carried out to sorting, then perishable organic constituent be fermented again.
The direct compost of changing food waste refers under manually operated condition, makes good use of oxygen animalcule effect and make the process of organic solid waste stabilization.Analyze from changing food waste composition aspect, in changing food waste, moisture, salinity, grease will exert an influence to compost quality.The water ratio of changing food waste is generally in 80%-90% left and right, and dewatering is poor.Excess moisture, divides compost inner filling water, hinders ventilation, causes microorganism in anaerobic state, degradation speed is slowed down, and produce the foul smell such as hydrogen sulfide, makes compost temperature decline simultaneously, has a strong impact on compost quality.Changing food waste contains a large amount of oil contents, easily conglomeration, caking, thus be unfavorable for piling being uniformly distributed and the effect of mass transmitting of the material such as oxygen of body internal temperature.A large amount of salinities, grease also can cause negative impact to the quality of the speed of microorganism decomposing organic matter and compost, and changing food waste is acidifying very easily.In addition, too low pH value can have a strong impact on the rate of decomposition of material.
Therefore, in order to ensure the quality of composting production, must carry out suitable pre-treatment to changing food waste, to meet the requirement of compost material.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of for the pretreated method of kitchen waste compost, by processing steps such as broken bag, drainage, screening, press dewaterings, as much as possible the impurity part in changing food waste material is screened out, and reduce the moisture in changing food waste organic materials, to adapt to composting process demand.
Of the present invention for the pretreated method of kitchen waste compost, comprise the following steps:
1) charging of changing food waste, changing food waste is poured onto on carrier bar broken bag conveying integrated machine through special kitchen garbage transport vehicle, in carrier bar course of conveying, material is carried out to preliminary solid-liquid separation;
2) carrier bar broken bag conveying integrated head section arranges roller bag-breaking device, and the sack in material is scratched, and carries out preliminary broken bag;
3) be delivered in trommel screen by chain belt conveyor through the changing food waste material of preliminary solid-liquid separation and broken bag, in trommel screen, bag-breaking device carries out broken bag to sack relatively little in material, make material spilling in bag, then by the aperture screening of trommel screen, large to large stretch of plastics bag, cloth etc. particle diameter foreign material are separated;
4) screen underflow of step 3) processing is entered in press dewatering equipment by worm conveyor, material is carried out to further press dewatering;
5) the changing food waste material after press dewatering is delivered in uniform distribution rubbish container by worm conveyor, and then outward transport, enters next step compost operation;
6) screen overflow is drained in Compressible rubbish container by the screen overflow outlet of trommel screen, and loose screen overflow material is carried out to compacting and further dehydration, screen overflow foreign material outward transport landfill or burning after compacting dehydration.
Of the present invention for the pretreated method of kitchen waste compost, in step 1): described carrier bar broken bag conveying integrated machine integrates conveying, drainage and broken bag function, adopts flat carrier bar carrier plate, and carrier plate gap is 2 ~ 5mm.
Of the present invention for the pretreated method of kitchen waste compost, in step 3): described trommel screen integrates broken bag and screening function, inside is furnished with bag breaking cutter by spiral-line.
Of the present invention for the pretreated method of kitchen waste compost, in step 4): described dehydration equipment adopts double spiral squeezer.
