Abstract
A kind of method for producing organic fertilizer using ozone processing antibiotic bacterium dregs, it is related to processing method and the recycling of antibiotic bacterium dregs, it is high the invention solves existing antibiotic bacterium dregs processing cost, the problems such as environmental risk is remained after processing, antibiotic bacterium slag liquid is delivered in the ozone-oxidizing device for being provided with ozone oxidation catalyst by the present invention, catalytic ozonation processing is carried out, the bacteria residue liquid after processing, which carries out precipitation is collected by centrifugation, prepares organic fertilizer.The present invention is easy to operate, and treating capacity is big, efficiently quick, can effectively degrade and the antibiotic that is remained in harmless treatment bacteria residue, be adapted to industrialized production；Meanwhile it can also complete the sterilizing to antibiotic bacterium dregs.After being handled more than, the degradable of residual antibiotic is can reach, has no residual harmful in the effect of the different kind organism body of natural environment.
Description
Technical field
The present invention relates to the method for innocent treatment of antibiotic bacterium dregs and recycling.
Background technology
Antibiotic is heavily used in the disease treatment of humans and animals for a long time, and makes an addition to animal with big therapeutic dose
In feed, to prevent Animal diseases and promote its growth.But most antibiotic can not be absorbed by organisms completely, there are about 90%
Antibiotic be discharged into original shape or metabolite form via the excrement and urine of sick humans and animals in ecological environment, through different ways
Footpath pollutes to soil and water body.China's ferment antibiotics annual discharge capacity of its bacteria residue about 200 in process of production
Ten thousand tons, a large number of nutrients is rich in bacteria residue, but because wherein containing a small amount of antibiotic residue, to prevent antibiotic residue from triggering ring
The risk of bacterial resistance in border, antibiotic bacterium dregs must first pass around processing and remove wherein antibiotic residue, then can just be subject to
Utilize.But up to the present, China's antibiotic bacterium dregs still lack safely and effectively innoxious and recycling processing method, absolutely mostly
Number can only burning disposal, not only cause ample resources to waste, and burning disposal cost is high, the risk that secondary pollution be present.Together
When, the high cost of bacteria residue processing is severely impacted the sound development of pharmaceutical industry.
It is revised according to 2008《National Hazard waste register》, antibiotic bacterium dregs belong to chemicals production of raw medicine
During culture medium waste, must be managed by hazardous waste.Antibiotic bacterium dregs contain to be produced among residual antibiotic and metabolism
Thing etc., it is a kind of special hazardous waste, it is such as mishandling, can be potentially hazardous to ecological environment and health generation,
Its harm has the characteristics that disguise, hysteresis quality, cumulative, concertedness and related property.For antibiotic bacterium dregs yield is big, place
The realistic problems such as difficulty is big are managed,《Pharmaceuticals industry pollution prevention technique policy》It is proposed " to encourage exploitation fermentation in (exposure draft)
Reutilization technology, innoxious process for treating, comprehensive utilization technique of the bacteria residue in production technology " policy and suggestion.
Ozonation technology is a kind of high-level oxidation technology, is widely used in the processing of all kinds waste water.It is mainly
Produced after being decomposed using ozone in water in the oxidability extremely strong oxidation intermediates, with water such as antozone, hydroxyl radical free radical
The reaction of organic and inorganic pollution, so as to realize deodorization, decolouring, sterilization and the purpose of organics removal.
The content of the invention
It is high the invention solves existing antibiotic bacterium dregs processing cost, the problems such as remaining environmental risk after processing, there is provided
It is a kind of to produce the high method of the simple to operate of organic fertilizer, treatment effeciency using antibiotic bacterium dregs.
A kind of method for producing organic fertilizer using ozone processing antibiotic bacterium dregs of the present invention, it is entered according to following steps
Capable：
First, antibiotic bacterium dregs are gathered, regulation solid content is that 8~10%, pH is 6~9, pending bacteria residue liquid is obtained, by antibiosis
Plain bacteria residue liquid is delivered in the ozone-oxidizing device for being provided with ozone oxidation catalyst, is carried out catalytic ozonation and is handled 2~5h；
2nd, the bacteria residue after the completion of reacting is centrifuged, by obtained bacteria residue precipitation and auxiliary material humic acid or bentonite
Mix drying to be granulated, make organic fertilizer；
The residual quantity of antibiotic in described antibiotic bacterium slag liquid is 600~700mg/L, pH=3.5~7.8；
The mol ratio of antibiotic and ozone is 1: 80~100.
The present invention operation principle be：On the one hand oxidable big point of hydroxyl radical free radical with strong oxidizing property caused by ozone
Sub- material is small-molecule substance so that antibiotic is degraded in bacteria residue；Another aspect antozone, hydroxyl radical free radical can have
Antibiotic resistant bacteria in effect inactivation bacteria residue, makes bacteria residue organic fertilizer without antibiotic resistant bacteria and does not trigger bacterium in soil
Resistance, safety in utilization improve.
The removal of antibiotic residue is different from organic matter removal in waste water in the high solid phase bacteria residue slurry of the present invention, at waste water
The target of reason is the organic matter of all kinds in water removal, and the target of bacteria residue processing is to remove antibiotic residue and retain albumen
The organic nutrient substance beneficial to plant growth such as matter, amino acid, i.e., organic matter is selective removal in bacteria residue.
The present invention has advantages below：
1. antibiotic residue can be degraded in the present invention, drug-fast bacteria is effectively inactivated in bacteria residue, and method program is simply easily grasped
Make, cost is low, fertilizer it is safe to use.
2. application prospect of the present invention is preferable, gardening, fruits and vegetables, farmland, forest or urban afforestation soil etc. can be applied to.
3. the present invention, which can be enterprise, solves the problems urgently to be resolved hurrily such as bacteria residue processing disposal, processing cost, while bacterium are reduced
The recycling of slag can be that enterprise brings potential economic benefit.
