Description
Technical field
The present invention relates to antibiotic bacterium dregs resource technology field, particularly relate to a kind of antibiotic bacterium dregs and prepare be rich in micropore
High performance active carbon method.
Background technology
China is maximum antibiotic primary producing country and exported country in the world, domestic product antibiotic yield 12 in 2013
Ten thousand tons, 30,000 tons of middle outlet accounts for the 70% of world market.The large-scale production of antibiotic also produces a large amount of antibiosis simultaneously
Plain bacteria residue.Because they contain, there are many noxious materials (such as antibiotic residues, heavy metal and Metabolic Intermediate), are arranged within 2002
Enter《Forbid the types of drugs catalogue used in feed and animal drinking water》, it is put within 2008《National Hazard waste name
Record》.Many researchs find that the antibiotic residue being exposed in natural environment can lead to the generation of antibiotic resistant bacteria.It defends in the world
Raw tissue (WHO) reports that antibiotic resistant bacteria has occurred and propagated in human and animal.Fresh antibiotic bacteria residue property is not
Stabilization, easily corruption simultaneously distribute stench, and finally threaten human health.Therefore, how antibiotic bacterium dregs safely and effectively to be handled
As the previous urgent problem of mesh.
The existing frequently-used bacteria residue treatment technology of pharmacy corporation is security landfill and burning, and security landfill is to put hazardous waste
A kind of disposal options in the soil are set or stored, the purpose is to bury or change the characteristic of hazardous waste, are suitable for disposition not
The hazardous waste of useful constituent or energy can be recycled.Since antibiotic bacterium dregs moisture content is high, security landfill is directly carried out, is deposited
The problems such as taking up a large area, cost of disposal is high and percolate, and it can result in waste of resources.Burning be it is a kind of most thoroughly, answer
With widest processing disposal technology, harmful components can be used with pyrolytic by most of pharmaceutical factory.But due to bacteria residue
Middle N element content is high, is several times to more than ten times of coal, unavoidably will produce a large amount of NOx, deal with improperly and easily cause environment
Problem.It is low additionally, due to its moisture content height, calorific value so that processing cost reaches 2000 yuan/t or so, seriously constrains pharmacy enterprise
The sound development of industry.Therefore, how economically and safely to handle and recycling antibiotic bacterium dregs are that pharmacy corporation is urgently to be resolved hurrily at present
Major issue.
Contain more rich organic matter in antibiotic bacterium dregs, such as crude fat, crude protein, carbohydrate, by pyrolytic technique,
Under conditions of anaerobic or anoxic, the larger molecular organics in bacteria residue can be made to be cracked into flammable micro-molecular gas (H2、CH4And CO
Deng), the methanol of liquid, acetone, acetic acid, acetaldehyde, tar, solvent naphtha and fixed carbon (coke, carbon black) etc., above-mentioned product can return
It receives and utilizes.Therefore, bacteria residue pyrolysis, which prepares activated carbon, has very big potentiality.
Application No. is 201310051119.7 patents to carry out activation system using ionic liquid and metal to antibiotic bacterium dregs
Standby activated carbon.Application No. is 201110388856.7 patents to prepare activated carbon using penicillin or terramycin, can be to bacteria residue
Carry out recycling treatment.But experiment finds that there are a large amount of protein in bacteria residue, the part is easy to cave in pyrolytic process
Deformation is unfavorable for the formation of micropore so that pore structure reduction.Bacteria residue is etched using containing aqueous slkali, removes part
After protein component, the high performance active carbon rich in micropore can be generated by carrying out activation.
