Technical field
The present invention relates to field of biological pharmacy, specifically, what relate to is a kind of method of medecamycin bacterium slag high-efficiency dehydration.
Background technology
At present, that produces along with antibiotic enterprise of China develops rapidly, the discarded mycelium (bacterium slag) that domestic antibiotics production enterprise produces, and the intractability faced is large, and the high problem of disposal cost becomes increasingly conspicuous.Medecamycin as antibiotic product one of them, the realistic problem that will become current a lot of antibiotic enterprise and have a headache the most is disposed in the process of the terminal discarded object produced.How by moisture content 94% ~ 96% medecamycin bacterium slag carry out deep dehydration process, reduce bacterium slag later stage cost of disposal, really accomplish the minimizing of bacterium slag, innoxious, stabilisation, resource.Become the technical barrier that antibiotic enterprise of China faces.
As everyone knows, it is deep dehydration link that medecamycin bacterium Slag treatment disposes a maximum difficult problem, because wheat enlightening bacterium slag belongs to the product after fermentable, is rich in organic matter, mycoprotein and degradation product thereof, also comprises a large amount of vegetable oil.Therefore its Separation of Solid and Liquid is very difficult.Current, mostly have employed the processed that horizontal spiral pusher centrifuge or disc separator carry out bacterium slag, after adding quantitative flocculant modifying function, make the centrifugal pressure that suspension produces under centrifugal force field, act on filter medium, make liquid become filtrate by filter medium, and solid particle is trapped within filter media surface, thus realizes Separation of Solid and Liquid; Although this technology is widely adopted, really do not reach the object of deep dehydration.Bacterium slag moisture content after centrifuge process is very high (general moisture content is about 80%) still, and be not easy to transport and later stage disposal, and later stage cost of disposal is higher, the stink that bacterium slag distributes seriously also affects surrounding enviroment.Cause the reason of wheat enlightening bacterium slag difficulty dehydration, except this equipment and technology limitation, be also rich in abundant organic characteristic with bacterium slag relevant.Mycelium is generally with suspension, and colloid etc. are uniformly distributed, and organic material component is complicated, and organic substance cellular water is wrapped up wherein firmly.Utilize centrifuge can only be separated Free water and a small amount of capillary water, and bacterium slag adsorption water and cell interior water still cannot remove.Want the real object reaching wheat enlightening rhzomorph bacterium slag dehydration minimizing, innovation and the use of chemical conditioning agent prescription must be strengthened, utilize modifier to destroy bacterium slag cellular elements constitution water, change the structure between bacterium solid impurity particle, improve bacterium slag high pressure dehydrating effect.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, provide a kind of method of medecamycin bacterium slag high-efficiency dehydration, the inventive method preparation manipulation is simple, and condition maturity, cost is low, pollution-free, Be very effective, and efficiency is high, has good application prospect.
For solving the problems of the technologies described above, the present invention is realized by following technical scheme:
The present invention relates to a kind of method of medecamycin bacterium slag high-efficiency dehydration, described method comprises the steps:
