Description
Technical field
The present invention relates to a kind of method for being enzymatically treated the antibiotic dregs of a decoction, belong to biomedicine field.
Technical background
The antibiotic dregs of a decoction are the filter residue of antibiotic bulk drug fermentate, and its main component is：Corn steep liquor, peptone, shallow lake
The biological mediums such as powder, soya-bean oil, beancake powder.Moisture reaches 90%, and solid medicine in the dregs of a decoction due to having separated antibiotic
Slag is mostly used at fermentation vat stacking or buried method all the time with being evenly dispersed in the form of suspension in liquid
Reason, has not only wasted effective nutriment in the antibiotic dregs of a decoction, and due to the medicineization in the discarded antibiotic dregs of a decoction
Length of schooling agent and the effect of complicated microorganism species leave long-term murder by poisoning hidden danger to the mankind.Due to current national environmental protection department
Efforts of investigation and prosecution is increased, and each antibiotics production enterprise generally uses four-effect evaporation, and energy consumption is very big, and very big pressure is brought to enterprise
Power, and this method does not meet energy-saving, the target of low-carbon economy of country's proposition yet.Shown according to web material：Mesh
The enterprise of preceding China's production antibiotic bulk drug has 81, produces about 1.4 hundred million tons of the antibiotic dregs of a decoction, annual each antibiotic bulk drug per year
The environment protection treating that manufacturing enterprise will spend substantial amounts of manpower, financial resources and be used for the antibiotic dregs of a decoction (needs land acquisition to deposit and to having
The charges for disposing pollutants of certain number, cleaning expense are paid by pass department) etc..
Because past production antibiotic is generally used during subsequent filter added with medical emetic white vitriol, seven
This several years rising trends of the price of water zinc sulphate are very fast, and the dregs of a decoction content of beary metal containing zinc is exceeded, and the dregs of a decoction of drying cannot be used for feed
And chemical fertilizer, so current antibiotics production enterprise is generally not added with white vitriol in process of production.For example：In October, 1994
CN1093681A (with the method and apparatus of the erythromycin waste residue extracting sulfuric acid zinc) patent announced by State Intellectual Property Office for 19th
Method, this method is need to be first by the natural air dry of the dregs of a decoction to leather hard, then passes through a kind of special combustion furnace coal or other combustions
Material is heated to the dregs of a decoction, heats burning, is therefrom reclaimed zinc oxide and is carried out the method for extracting sulfuric acid zinc with sulfuric acid reaction.The invention
Although solving the recycling application of the dregs of a decoction, because the energy consumption produced in process of production is big, cost is high, rainy season or winter are run into
Season can not produce again, and residual sour waste residue, the waste liquid after filtering pollute environment again.Due to without obvious social benefit and economy
Benefit, is not promoted and applies always for many years.And for example on May 11st, 2005, State Intellectual Property Office announced：By Zhejiang
CN200310108527 (processing method of the bacteria residue containing zinc antibiotic) patent of polytechnical university's invention, the method for the patent is to utilize
The dregs of a decoction of alkalescence are diluted, are adjusted to acidity by hydrochloric acid, sulfuric acid or acetic acid and water, then adsorb the dregs of a decoction with chelating ion exchange resin
In metallic zinc, then the zinc in resin is departed from heavy dose of acid or hydrochlorate, to complete the separation of zinc and the dregs of a decoction, to realize medicine
The recycling application of slag.But due to not sayed and language this process employs the pollution of substantial amounts of acid supplement and water resource, discharge.It is heavier
Want be heavy dose of acid supplement and expensive ion exchange resin (due to the limitation of adsorption capacity and regenerant consumption, mainly
Recovery for rare precious metal) come for waste dregs generated application, production cost is well imagined.So antibiolics
The problem of recycling of slag, innoxious application are still at present anxious to be resolved.And for example it is related to one in patent of invention 200610005585
The method for reclaiming zinc using erythromycin waste residue and Yeast protein being produced with the erythromycin waste residue after dezincification is planted, this method this method is
The content of zinc in wet erythromycin waste residue is measured using reactor, then extractant is put into aforesaid reaction vessel, in a kettle.
