Description
Technical field
The invention belongs to food garbage process field, and in particular to a kind of swill treatment technique.
Background technology
City dining room can all produce substantial amounts of swill daily, and former, restaurant swill is generally used to be transported to plant feeds
Animal is supported, what is in general fed is pig.But because swill is apt to deteriorate in transportation, pollution, produce various causing a disease
Bacterium, causes the animal fed to be fallen ill, so that national implementation policy does not allow to recycle swill nutrition purposes, especially for feeding animals.
If swill cannot be used for nutrition purposes, especially for feeding animals, must just find other schemes to process substantial amounts of swill.Swill due to
Mainly swill, wherein main chemical composition is starch, cellulose, protein, lipid and inorganic salts, simultaneously containing few
The trace elements such as amount nitrogen, phosphorus, potassium, calcium.Therefore, according to its property, swill treatment can use two methods, i.e. swill regeneration fertilizer
Material and swill regenerative feedstuff.
《City management and science and technology》The side that swill is regenerated as fertilizer is disclosed in document " discussion of municipal swill management "
Method.
Swill regeneration fertilizer technology on the market is primarily present problems with now：（1）Swill occurs in transportation
It is rotten, stench is produced during to treatment ground, pernicious gas is released, staff's body is impacted；（2）Fermentation time is long, place
Reason efficiency is low, but restaurant swill is daily continually to produce ground；（3）Restaurant, hotel, food are derived from because swill is most of
The public places such as hall because simple swill is not only included in swill, also waste paper, wooden chopsticks, cigarette end, detergent etc. other
Waste；Waste paper and wooden chopsticks contain cellulose, and cigarette end contains the heavy metals such as tar, BaP, lead can be polluted to soil reclamation.
BaP is the very strong polycyclic aromatic hydrocarbon of a kind of toxicity and carcinogenicity, can be produced in the unburnt residue of cigarette
Raw, food, edible oil of overheat for burning etc. can all produce BaP.Therefore, for being containing relatively many in restaurant swill
BaP,《Journal of Heze University》" BaP is to the source of BaP in the harm of human body and food and anti-for Literature
Control " discloses BaP and applies soil as fertilizer, and BaP can be caused to exist in soil again, and then pollutes the grain of plantation
Crop, eventually through grain influence people it is healthy.
Therefore during swill is converted into fertilizer, it is that extremely have must above-mentioned harmful components to be removed or is reduced
Strategic point, but in present swill conversion fertilizer technology disclosed on the market, the technology all not processed for BaP.And
A kind of garbage processes method disclosed in Application No. 201510650092.2, disclosing strain mixed liquor includes geotrichum candidum
Bacterium, Leuconostoc mesenteroides, whiterot fungi, black-koji mould, applicant are degraded using whiterot fungi to cellulose, and in fact,
Whiterot fungi can also degrade to BaP, but whiterot fungi is a kind of fungi, and many fungies are all conditioned pathogens, many
Filamentous fungi can produce a large amount of spores, cause the disease of people, livestock and other plant, cause secondary pollution.Therefore white rot is used
Bacterium is unsatisfactory to carry out treatment to BaP.
Flavobacterium does not easily cause secondary pollution, is a kind of ideal inorganic agent, and polycyclic aromatic hydrocarbons (PAH) can be dropped
Solution, but Flavobacterium is less than whiterot fungi ground to the degradation capability of BaP, to improve the degradation capability of Flavobacterium except cultivating
Outside its dominant strain, it is also highly important to have a suitable growing environment.
The content of the invention
Present invention aim to overcome that the defect of prior art, there is provided urban catering swill treatment technique, with can be to sky
The advantage of the various chemical compositions removal in gas pollution.
To achieve these goals, the technical scheme that the present invention takes is as follows：
Urban catering swill treatment technique, comprises the following steps：
（1）Separation of solid and liquid, solid in swill and liquid are separated；
（2）Liquid is fabricated to biodiesel, solid is crushed；
（3）Compare 1000 according to weight with potassium salicylate in fixed crushed material:1 ~ 5 is mixed, and forms mixture, and mixture is adjusted
Save pH value to 5 ~ 6.5；
（4）Will be by step（3）Mixture compare 150 according to weight with many bacterium mixed liquors:4 ~ 10 are mixed, the multi-cultur es
Mixed liquor includes Flavobacterium 45 ~ 800,000 cfu/ml, Leuconostoc mesenteroides 200 ~ 4,000,000 cfu/ml, 200 ~ 400cfu/ of streptomycete
Ml, 200 ~ 400cfu/ml of staphylococcus saprophyticus；
（5）Stirring at normal temperature is fermented, and divulge information 24 ~ 36h, and ventilation 10L/min, stir speed (S.S.) is made fertilizer for 5 ~ 10r/min.
In the present invention, staphylococcus saprophyticus is decomposed to grease, streptomycete can be by breaks down proteins into amino acid；Energy
Enough various enzymes for producing can promote the decomposition of grease and cellulose, Leuconostoc mesenteroides energy fermenting carbohydrate produce various acid with
Alcohol；Flavobacterium to the BaP contained in the materials such as food and cigarette end is degraded, with Flavobacterium match somebody with somebody by staphylococcus saprophyticus
Close, improve the degradation efficiency of Flavobacterium so that the clearance of BaP is more than 90%.Flavobacterium, strepto- are also found simultaneously
Bacterium, staphylococcus saprophyticus with the use of can heavy metal play degradation, heavy metal removing rate reaches more than 80%.Meanwhile,
Other strains are played facilitation by using cooperatively for various enzymes under decomposition efficiency Leuconostoc mesenteroides effect high, are accelerated
Whole fermentation process.
The present invention compared with prior art, with advantages below：
The present invention degrades to BaP, it is to avoid contain BaP in fertilizer and then soil is polluted；The present invention is simultaneously
Heavy metal to containing in food, cigarette end, detergent is removed.Present invention employs salicylate as additive be because
Facilitation is played in growth for salicylate to Flavobacterium, while potassium ion can increase the effect of fertilizer.Lead in the present invention
Air quantity is the preferable condition of Flavobacterium growth fraction for 10L/min.
