Description
Technical field
The invention belongs to environmental protection technical fields, and in particular to a kind of biodegrading process of vinyon.
Background technology
It is busy order takeaway, bad weather orders takeaway, nowadays order takeaway into the life normality of many people.But with
The surge for take-away amount, packing box, the packaging bag for taking out consumption are also increasing.Thing followed white pollution, also results in
Everybody attention.
The report display of O2O industry developments is taken out by China, and 2016 online to take out the user's accounting consumed 3 times weekly or more and reach
63.3%.According to this consumption pattern, 400,000,000 are at least sent out weekly and is especially sold, thus generate 400,000,000 disposable to-go boxs and one
The waste of secondary property tableware.Disposable tableware is taken out into new " white pollution ".In this regard, Chinese Academy of Social Sciences of Shaanxi Province researcher Xie Yu
Peak indicates, solves pollution problem caused by disposable tableware, and in addition to working hard on material, multi-purpose degradation material is more important
Be perfecting system, clearly defining responsibilities.
Shaanxi Shanix Academy of Social Sciences researcher Xie Yufeng：" this is the new problem derived with internet economy, entirely
It is the generation of new pollution sources.As for say can provide degradable (tableware) this be technological layer need break through ask
Topic, it would be desirable to from system norms level, start to keep in mind hand normal constraint, this new pollution row that the internet economy epoch occur
For.”
Plastic foam is not perishable in nature, is not easy to be degraded by microorganisms, even if it is buried also can polluted underground water source, break
Bad soil texture makes the cereal crops underproduction, therefore must handle plastic foam.
The processing common method of plastic foam is burning disposal at present, although burning disposal can handle a large amount of plastic blister
Foam, but will produce a large amount of toxic gas during the burning process, it is serious to pollute air and atmospheric environment.Therefore, it is necessary to find solution
The certainly effective way of " white pollution ".
Invention content
In view of this, the present invention provides a kind of biodegrading process of vinyon, plastics is allow easily to return repeatedly
It receives and uses, by processing after waste plastics recovery, product can be become again, gasoline and diesel oil can also be made, effectively solve plastics
Environment, social concern caused by pollution.
The technical scheme is that：A kind of biodegrading process of vinyon, which is characterized in that including walking in detail below
Suddenly：
S1. the plastic raw materials of collection are sieved, is cleaned up, carried out mechanical damage and reduce its volume；
S2. it will pass through pretreated raw material, and be put into immersion treatment 24-72h in soak, it is 37-60 DEG C to keep soaking temperature；
S3. cleaning is added in fermentation tank by the raw material impregnated and carries out fermentative degradation；
S4. the mixed liquor by degradation is collected, second extraction is waited for recycle.
Soak in the step S2 includes the component of following parts by weight：Calcium hydroxide 6-13, sodium hydroxide 9-15,
Ammonium chloride 6-18, ammonium hydrogen carbonate 11-26, triethanolamine 5-19, isopropanol 4-9.
Further, a concentration of 0.12moL/L-0.46moL/L of the soak.
Soak in the present invention, can with the functional groups of the network skeleton of the three-D space structure of plastic raw materials,
The bonding tightness of its three-D space structure is set to reduce, structure becomes loose, convenient for the infiltration of follow-up mushroom more comprehensively to connect
Touch degradation.
Further, the technique of the fermentative degradation in the step S3 is：Addition total plate count is 1.58 ╳ 106-2.56
╳107The mixed bacteria liquid of cfu/g, fermentative degradation 5-10 days under 23-34 DEG C, pH6.6-8.0.
Further, the mixed bacteria liquid includes the component of following parts by weight：Simple mould 5-11, arthrobacter paraffineus 5-
11, Tabin aspergillus bacterium 10-17, aspergillus flavus 19-28, culture medium 30-49；The total plate count of the letter mould is 3.4 ╳ 104-6.7
╳105cfu/g；The total plate count of the arthrobacter paraffineus is 2.9 ╳ 105-1.2╳106cfu/g；The bacterium of the Tabin aspergillus bacterium
It is 1.2 ╳ 10 to fall sum6-2.3╳107cfu/g；The total plate count of the aspergillus flavus is 5.4 ╳ 104-7.2╳105cfu/g。
Further, in the step S4, the average particle size to the mixed liquor by degradation of collection is needed to carry out
Test, then spare processing up to standard；It is not up to standard then to repeat step S3 operations once.
In the present invention, the strain that the mixed bacteria liquid uses, the letter mould
（Penicilliumsimplicissimum）：Simple mould is a kind of common soil fungi microorganism, as soil inhabitant,
Higher lignin-degrading enzymes can be generated, can be converted and lignin degrading.
The arthrobacter paraffineus（Arthrobacterparaffineus）：Number：AS1.1464, Classification system：
Arthrobacterparaffineus, Chinese bacterium name：Arthrobacter paraffineus, bacterium source：ATCC15591.
The Tabin aspergillus bacterium（Aspergillustubingensis）：By the study found that Tabin aspergillus bacterium can be
Polyurethane surface is grown, and biological respinse occurs for the enzyme by being generated in growth course and plastics, is destroyed between plastic molecules or poly-
Close the chemical bond between object；Meanwhile this fungi also uses the physical strength of its mycelia, helps " breaking into two with one's hands " plastic polymer.It grinds
Study carefully and point out, in the case where " Tabin aspergillus bacterium " acts on, is difficult to the plastics degraded in the natural environment originally, can be clearly visible within two weeks
Biodegradation process, after two months the plastic polymer on its culture medium disappear substantially.
The aspergillus flavus（Aspergillusflavus）：Aspergillus flavus, Fungi Imperfecti, a kind of common saprophytic fungus.It is more common in
On mouldy grain, grain product and the organic matter of other mould corruption.Bacterium colony growth is very fast, short texture, surface celadon, the back side without
Color is slightly brownish.There are many complicated branch mycelia to constitute for thalline.Vegetative hyphae, which has, to be separated；A part of shape of aerial hyphae
Grow up and coarse conidiophore, top generates flask shape or subsphaeroidal top capsule, and surface generates many stigmas（It is generally double
Layer）, on stigma generate the shaggy spherical conidium of string.Conidiophore, top capsule, stigma and conidium synthesis
Spore head can be used for generating the common strain in amylase, protease and phosphodiesterase etc. and brewery industry.
The mixed bacteria liquid of the present invention, the flora organizational form of inventor's design through the invention, just as " the small society of flora
Meeting ", allowing different strains, Each performs its own functions.A part of mushroom in flora is the macromolecules degradations of plastics at small molecule, another portion
Divide mushroom that small molecule is absorbed or is transformed into other isomers again, the synergistic between mixed bacteria liquid strain is multiple through the invention
Match, it can be effectively by the macromolecules degradation of plastics at small molecule.The setting of Mixed Microbes syntaxial system through the invention, generation
The approach of thanking reduces the competition that nutriment is fought between bacterium and bacterium, realizes the Ecological Stabilization of entire Mixed Microbes system, Neng Gouyou
Plastic degradation is provided new environmental protection for white-pollution control by effect ground as small molecule particle in order to secondary recycling
Approach.
