Abstract
The invention discloses a kind of kitchen garbage biological treatments, it is related to kitchen garbage treatment process technical field, solves the problems, such as existing Food waste treatment method not environmentally, the invention includes the following steps: (1) separates kitchen garbage, (2) preliminary working is carried out to the dry matter after separation, (3) biofermentation is carried out to dry matter after preliminary working and obtains insect protein feed, (4) cultured insect is carried out using insect protein feed, (5) insect of cultivation is subjected to processing or directly application, kitchen garbage is carried out separating treatment by above step by the present invention, it will be re-used after kitchen garbage harmless treatment, it is not only environment friendly and pollution-free, and turn waste into wealth, obtain more values.
Description
Technical field
The present invention relates to kitchen garbage treatment process technical fields, more particularly to a kind of kitchen garbage biological treatment
Technique.
Background technique
With the continuous prosperous development of catering industry, the yield of kitchen garbage is continuously increased.Kitchen garbage is as city
The waste the most universal generated in daily life, has rich in starch food, plant fiber, animal protein and fats etc.
Machine object has moisture content high, and grease, salt content are high, preferably rot smelly.
For a long time, there is no carry out concrete management to kitchen garbage in China.The kitchen garbage that residential households generate, generally
Be to be collected with other domestic garbage mixings, and eventually enter into system for treating municipal solid waste, and the kitchen garbage of catering trade or
It is fed pigs untreatedly by outskirts of a town pig farmer, delivers the unqualified pig of thousands of heads for sale；Or it is recycled to refine by illegal retailer and discard
After grease, incorporation edible oil is sold.Simultaneously as kitchen garbage easily rots, can generate make one to be difficult to receive it is bad
Impression, such as penetrating odor, and leftovers soup, puke content are very big in the kitchen garbage that catering industry generates, and are easy collecting, transporting
It is defeated to leak on the way, cause secondary pollution.For this purpose, in many places, kitchen garbage is directly landfilled processing.Above for kitchen rubbish
The processing method of rubbish all not environmentally, does not fundamentally carry out effective, free of contamination processing to kitchen garbage.
Summary of the invention
It is an object of the invention to: in order to solve the problems, such as existing Food waste treatment method not environmentally, the present invention is provided
A kind of kitchen garbage biological treatment.
The present invention specifically uses following technical scheme to achieve the goals above:
A kind of kitchen garbage biological treatment, which comprises the following steps:
(1) it is separated after collecting kitchen garbage, isolates moisture, oil and dry matter；
(2) dry matter obtained after separation is subjected to preliminary working, including smashes and grinds, filters sorting and drying process；
(3) dry matter Jing Guo preliminary working is subjected to biofermentation, the dry matter after biofermentation is insect protein feed；
(4) cultured insect is carried out with insect protein feed；
(5) biological organic fertilizer is obtained after the insect of cultivation being further processed, or insect living body is directly used for other animals
Breeding feed.
It is further improved, moisture isolated in step (1) is further separated, underflow and thin liquid are obtained；It will
Water soluble fertilizer is made after carrying out biofermentation processing in underflow, after thin liquid centralized collection heel row is handled toward Sewage Disposal
Discharge.
It is further improved, oil isolated in step (1) is finely separated, is further separated out residual in oil
The moisture stayed, and it is filtered to remove impurity present in oil, the oil after fine separation can be used as biodiesel raw material.
It is further improved, insect described in step (4) is the black soldier flies larva of 2-5 days ages in days.
It is further improved, animal described in step (5) is lobster, giant salamander and all kinds of poultry.
It is further improved, biological organic fertilizer includes that insect ontology is arranged by smashed powder and insect in step (5)
Let out the substance after object is processed.
Beneficial effects of the present invention are as follows:
Kitchen garbage progress separating dry space from moist space is handled respectively, targetedly heterogeneity in kitchen garbage can be carried out thorough
The processing of environmental protection, while biofermentation is carried out to the dry matter in kitchen garbage using biology, it can be very effective by kitchen
Dry matter carries out harmless treatment in rubbish, while being converted into the feed that can be used to carry out insect raising, in processing kitchen rubbish
Turn waste into wealth while rubbish, generates certain economic value.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Specific embodiment
In order to which those skilled in the art better understand the present invention, with reference to the accompanying drawing with following embodiment to the present invention
It is described in further detail.
Embodiment 1
First with strainer by kitchen garbage dry matter and the liquid such as grease carry out initial gross separation, the dry matter after separation leads to again
It crosses extruding and further squeezes out remaining grease liquid.
Dry matter after separation is crushed by grinding device, and smashed dry matter carries out granularity screening and filtering,
The biggish dry matter of particle reenters grinding device and carries out separating twice, dry matter particle concentration is dried, drying is adopted
Use air-heater；Then the dry matter particle after drying is carried out Concentrated fermentation 1.5 days, the dry matter after fermentation is for black soldier flies children
The cultivation of worm, black soldier flies larva select 4 days larvas of age in days, and larva can be used for the feeding of other animals for 10 days or so by raising
Material, or be further processed into organic fertilizer.
Grease liquid after separation is separated oil with moisture by oil water separator, by moisture by centrifuge into
After row centrifugation, thin liquid and the underflow containing suspended material are isolated；There is loom less in thin liquid, it is normal by Sewage Disposal
It can qualified discharge after rule processing；The content of organic matter is higher in underflow, is made after organic matter is fermented using fermentation procedure
Water soluble organic fertilizer.Bio-fuel-oil is made with after fine separate by further filtering in oil.
