Description
Technical field
The invention belongs to field of garbage disposal, 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 is formed 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., main based on materials such as starch based, foodstuff fibre class, animal tallow classes, 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 high, if greatly can reduce the heat energy utilization of burning with other domestic garbage mixing burnings, simultaneously lipid material wherein becomes the important factor producing dioxin under the catalytic condition of heavy metal; Landfill disposal then can produce a large amount of biogas and percolate, causes secondary pollution to environment, and therefore current perishable organism takes biological treatment mostly.
Compost is the most ancient technology of garbage disposal of China, the technics comparing of composting technology is simple, be suitable for the refuse treatment that perishable organic content is higher, and the waste that the stone, metal, glass, plastics etc. in rubbish can not be decomposed by the microorganisms must go-no-go out otherwise processed.To ensure during compost that organic fertilizer product is up to state standards, just fresh rubbish first must be carried out sorting, then perishable organic constituent be fermented again.
The direct compost of changing food waste refers under manually operated condition, makes good use of the process that oxygen animalcule effect makes organic solid waste stabilization.Analyze from changing food waste composition aspect, in changing food waste, moisture, salinity, grease will have an impact to compost quality.The water ratio of changing food waste is generally at about 80%-90%, and dewatering is poor.Excess moisture, makes compost inner filling water divide, hinders ventilation, cause microorganism to be in anaerobic state, degradation speed is slowed down, and produces the foul smell such as hydrogen sulfide, make compost temperature decline simultaneously, have a strong impact on compost quality.Changing food waste contains a large amount of oil contents, easy conglomeration, caking, thus is 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 salinity, grease also can cause negative impact to the quality of the organic speed of microbial decomposition 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, suitable pre-treatment must be carried out 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 portion in changing food waste material is screened out, and the moisture reduced 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:

3) the changing food waste material through preliminary solid-liquid separation and broken bag is delivered in trommel screen by chain belt conveyor, 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, the Large stone foreign material such as large stretch of plastics bag, cloth are separated;
4) screen underflow of step 3) process is entered in press dewatering equipment by worm conveyor, further press dewatering is carried out to material;
5) the changing food waste material after press dewatering is delivered in uniform distribution rubbish container by worm conveyor, then transports outward, and enters next step compost operation;
6) screen overflow is drained in Compressible rubbish container by the screen overflow outlet of trommel screen, carries out compacting and dehydration further to loose screen overflow material, the screen overflow foreign material outward transport landfill after compacting dehydration or burning.
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, and adopt flat carrier bar carrier plate, 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.
