Description
Technical field
The present invention relates to the harmless treatment of polypeptide antibiotics bacteria residue and resource utilization method.
Background technology
China is antibiotics production big country, and China's antibiotic yield in 2011 is 111.6 ten thousand tons and accounts for world market total amount
More than 70%.The production of antibiotic mainly based on class of fermenting, often produces 1t antibiotic and about produces 8-10t wet bacteria slags.Antibiosis
A large number of nutrients is rich in plain bacteria residue, but because wherein containing a small amount of antibiotic residue, to prevent antibiotic residue from triggering environment
The risk of middle bacterial resistance, antibiotic bacterium dregs must first pass around processing and remove wherein antibiotic residue, then can just be subject to profit
With.If mishandling, ecological environment and health can be seriously endangered.Antibiotic bacterium dregs have been put into new revision within 2008
《National Hazard waste register》, culture medium waste that antibiotic bacterium dregs belong to during chemicals production of raw medicine must be by danger
Dangerous waste is managed.Therefore how rationally to dispose antibiotic bacterium dregs, solve antibiotic bacterium dregs outlet have become very compel
Cutting for task.
Paradigm polypeptide class antibiotic mainly include bacitracin, colistin, capreomycin, its bacteria residue mainly by mycelium,
Remaining culture medium, fermentating metabolism product composition, wherein containing substantial amounts of polysaccharide, protein and several amino acids and trace element,
Contain a small amount of antibiotic residue simultaneously.And domestic pharmaceutical factory is substantially carried out burning disposal to this kind of antibiotic bacterium dregs at present, but by
Larger (about more than 75%) in bacteria residue water content, not only burning cost is too high, can bring new atmosphere pollution risk, and cause
Resource serious waste.At present, the problem has had influence on the sound development of China's pharmaceutical industry.Therefore, find a kind of as what is the need
Except nutriment contained by bacteria residue moderate resistance life element residual, rational exploitation and utilization bacteria residue, the innoxious and recycling of bacteria residue is realized, this is right
Economize on resources, prevent the pollution of the environment, developing a circular economy has great importance.
For the realistic problem such as antibiotic bacterium dregs yield is big, intractability is big,《Pharmaceuticals industry pollution prevention technique political affairs
Plan》" reutilization technology of encouraging exploitation fermentation bacteria residue in production technology, harmless treatment skill are proposed in (exposure draft)
Art, comprehensive utilization technique " policy and suggestion.
It is main to close in the method that the relevant polypeptide antibiotics bacteria residue processing delivered both at home and abroad at present utilizes with Fertilizer Transformed
Note the wherein removal of antibiotic residue and the fertilizer efficiency as organic fertilizer, not yet concern handle after bacteria residue and made fertilizer whether
Containing polypeptide antibiotics drug-fast bacteria, whether there is security as Fertilizer application.
The content of the invention
It is high the invention solves existing polypeptide antibiotics bacteria residue processing cost, environmental risk etc. is remained after processing and is asked
A kind of topic, there is provided method that organic fertilizer is produced using polypeptide antibiotics bacteria residue.Polypeptide antibiotics of the present invention includes bar
Bacterium peptide, colistin, capreomycin.
A kind of method that organic fertilizer is produced using polypeptide antibiotics bacteria residue of the present invention, it is to follow the steps below
's：
First, fresh polypeptide class antibiotic bacterium dregs are gathered, adds water to adjust moisture content to 80%~90%, obtains pending bacteria residue；
2nd, add in the bacteria residue handled through step 1, mix using persulfate as oxidant；Wherein, polypeptide antibiosis
The mol ratio of residual antibiotic and over cure acid group in plain bacteria residue is 1：40~70；
3rd, the bacteria residue handled through step 2 is placed in 70~95 DEG C of water-baths, 0.3~1.0h of oxidation processes；
4th, the bacteria residue after the completion of step 3 oxidation reaction is cooled to room temperature, in the bar that rotating speed is 4000~8000r/min
Under part, 20min is centrifuged, obtained bacteria residue precipitation is mixed into drying with auxiliary material humic acid or bentonite is granulated, that is, completes institute
That states produces organic fertilizer using polypeptide antibiotics bacteria residue；
The residual quantity of polypeptide antibiotics is 800~1500mg/kg, pH 6.5 in described polypeptide antibiotics bacteria residue
~8.0.
The present invention principle be：By thermal activation persulfate, potentiometric titrations yield, potentiometric titrations are improved
There is very strong oxidisability, can effectively destroy polypeptide antibiotics molecular structure, remove antibiotic residue, while kill in bacteria residue
Antibiotic resistant bacteria, make bacteria residue organic fertilizer without antibiotic resistant bacteria and do not trigger bacterial resistance in soil, improve fertilizer
Safety in utilization, so as to realize the harmless treatment of bacteria residue and recycling.
The removal that polypeptide antibiotics remains in the high solid phase bacteria residue slurry of the present invention is different from organic matter removal in waste water, gives up
The target of water process is the organic matter of all kinds in water removal, and the target of bacteria residue processing is to remove antibiotic residue and retain
The organic nutrient substance beneficial to plant growth such as polysaccharide, protein, amino acid, i.e., organic matter is selective removal in bacteria residue,
And thermal activation improves the clearance of polypeptide antibiotics residual, while have the function that to kill drug-fast bacteria in bacteria residue.
Advantages of the present invention：
1. fertilizer reparation technology is simple in the present invention, easily operated, processing cost is low.
2. polypeptide antibiotics degradation efficiency is high in the present invention, polypeptide antibiotics drug-fast bacteria can be killed effectively in bacteria residue
Go out, fertilizer it is safe to use.
3. the oxidant used in the present invention is potassium peroxydisulfate or ammonium persulfate, they change during bacteria residue is handled
Into potassium sulfate or ammonium sulfate, be advantageous to improve the content for producing the nutritional ingredient of potassium and nitrogen in fertilizer.
4. the polypeptide antibiotics residual quantity that the present invention is handled is 800~1500mg/kg, content is very high, and bacteria residue
In also have other complicated ingredients, the use to oxidant causes very big difficulty, and the polypeptide for how handling such high concentration resists
Raw plain bacteria residue, is currently that no correlation technique can be used for reference.The present invention is using thermal activation persulfate to polypeptide antibiotics
Removal efficiency is up to 99.5%, and sterilizing ability is strong, and process cycle is short, can be completed no more than 1 hour.
5. treatment process condition is relatively mild in the present invention, low for the organic matter nutrients destructiveness in bacteria residue, have
Beneficial to the recovery for realizing nutriment.
6. the present invention can provide a kind of method of bacteria residue safe disposal and recycling for pharmacy corporation, at reduction
Cost is managed, certain economic benefit is brought for enterprise.
