Description
Technical field
The present invention relates to a kind of method of the enzymatic treatment microbiotic dregs of a decoction, belong to biomedicine field.
Technical background
The microbiotic dregs of a decoction are the filter residue of microbiotic bulk drug fermented product, and its main component is: the biological mediums such as corn steep liquor, peptone, starch, soya-bean oil, soybean cake powder.90% is reached owing to being separated moisture content in the antibiotic dregs of a decoction, and the solid dregs of a decoction are evenly dispersed in liquid with the form of suspension, mostly adopt fermentation vat to stack or buried way process all the time, not only waste effective nutritive substance in the microbiotic dregs of a decoction, and leave long-term murder by poisoning hidden danger to the mankind due to the effect of the medical chemistry preparation in the discarded microbiotic dregs of a decoction and complicated microorganism species.Because current national environmental protection department efforts of investigation and prosecution strengthens, each production of antibiotics enterprise generally adopts four-effect evaporation, and energy consumption is very large, brings very large pressure to enterprise, and this method does not meet the energy-saving and cost-reducing of country's proposition yet, the target of low-carbon economy.Show according to web material: the enterprise of the microbiotic of China's production at present bulk drug has 81, produce the microbiotic dregs of a decoction about 1.4 hundred million tons per year, annual each microbiotic production of raw medicine enterprise all will spend a large amount of manpowers, financial resources for the environment protection treating (need land acquisition to deposit and pay effluent charge, the cleaning expense of certain number to relevant department) etc. of the microbiotic dregs of a decoction.
In subsequent filter process, medical emetic Zinc Sulphate Heptahydrate is added with because past production microbiotic generally adopts, this several years rising trends of the price of Zinc Sulphate Heptahydrate are very fast, dregs of a decoction heavy metal content containing zinc exceeds standard, the dregs of a decoction of drying can not be used for feed and chemical fertilizer, so current production of antibiotics enterprise does not generally add Zinc Sulphate Heptahydrate in process of production.Such as: CN1093681A (method and apparatus with the erythromycin waste residue extracting sulfuric acid zinc) patented method announced by State Intellectual Property Office on October 19th, 1994, the method be need first by the dregs of a decoction nature air dry to leather hard, again by a kind of special roasting kiln coal or other fuel is heated to the dregs of a decoction, heating flame, therefrom reclaim zinc oxide and carry out the way of extracting sulfuric acid zinc with sulfuric acid reaction.Although this invention solves the resource utilization application of the dregs of a decoction, because the energy consumption produced in process of production is large, cost is high, run into rainy season or winter cannot produce again, and residual sour waste residue after filtering, waste liquid pollute environment again.Due to without obvious Social benefit and economic benefit, be not promoted for many years always and apply.And for example on May 11st, 2005, State Intellectual Property Office announced: CN200310108527 (treatment process containing the zinc antibiotic bacterium slag) patent of being invented by Zhejiang Polytechnical University, the method of this patent utilizes hydrochloric acid, sulfuric acid or acetic acid and water to be diluted, be adjusted to acidity by the dregs of a decoction of alkalescence, then by the metallic zinc in the chelating ion exchange resin absorption dregs of a decoction, with heavy dose of acid or hydrochlorate, the zinc in resin is departed from again, carry out being separated of zinc and the dregs of a decoction, to realize the resource utilization application of the dregs of a decoction.But owing to this process employs a large amount of acid supplements and water resources, the pollution of discharge is not sayed and language.The more important thing is that heavy dose of acid supplement and expensive ion exchange resin (due to the restriction of loading capacity and regenerant consumption, being mainly used in the recovery of rare noble metal) come for waste dregs generated application, production cost is well imagined.So the resource utilization of the microbiotic dregs of a decoction, innoxious application are still problem anxious to be resolved at present.And for example relate in patent of invention 200610005585 and a kind ofly utilize erythromycin waste residue to reclaim zinc and produce the method for Yeast protein with the erythromycin waste residue after dezincify, the method the method is the content utilizing reactor to measure zinc in wet erythromycin waste residue, again extraction agent is put in aforesaid reaction vessel, in a kettle. solid-liquid separation is carried out to material, solution after separation is hydrolyzed or electrolysis, directly zinc powder is obtained after electrolysis, finally the dregs of a decoction after separation are used for protein fodder maybe by after this dregs of a decoction sterilizing, inoculation yeast bacterial classification ferments, and produces Yeast protein.Because the method adopts reactor to be separated zinc, after being extracted by zinc, erythromycin waste residue is still in suspension state, also needs four-effect evaporation liquid evaporation could be gone out.Fundamentally do not solve the high problem of erythromycin waste residue moisture content.
