The process includes the following steps: 1. measuring the zinc content in the wet erythromycin medicine dregs inside the reaction kettle; 2. throwing extractant into the reaction kettle; 3. solid-liquid separation of the reaction material; 4. hydrolyzing or electrolyzing the separated solution to obtain zinc powder; and 5. using the residual erythromycin medicine dregs directly as feed protein or sterilized and fermented to produce yeast protein. The present invention has the features of simple production apparatus and process, low cost and environment friendship.
Description
Technical field
The present invention is novel to relate to a kind of method of utilizing erythromycin waste residue to reclaim zinc and produce Yeast protein with the erythromycin waste residue after the dezincify.
Background technology
Erythromycin waste residue is the filter residue of erythromycin bulk drug fermented product, and its main component is: biological mediums such as starch, soybean cake powder, corn steep liquor, soya-bean oil, peptone.Because of being added with medical emetic Zinc Sulphate Heptahydrate in the filtration procedure, so in the erythromycin waste residue,, can't be used for feed or fertilizer because the zinc content overproof makes its different and other microbiotic dregs of a decoction.All the time, mostly adopt the way that stack on the level land or bury in the mountain valley for erythromycin waste residue, not only wasted the effectively utilization of nutritive substance in the erythromycin waste residue, and because the effect of the microorganism species of medical chemistry preparation in the depleted erythromycin waste residue and complexity has stayed secular toxic hidden danger to the mankind.Show according to web material: there are 46 families in the enterprise of the erythromycin of China's production at present bulk drug, produce about 8,700 ten thousand tons of erythromycin waste residue per year, annual each erythromycin production of raw medicine enterprise all will spend the environment protection treating that great amount of manpower, financial resources are used for erythromycin waste residue, needs land acquisition to deposit and pay to relevant department the effluent charge, cleaning expense etc. of certain number simultaneously.
In recent years because the shortage of " zinc " resource, existing many people attempt associating and extract the technology of " zinc " in the depleted erythromycin waste residue.But owing in the dregs of a decoction only there be about 2.5% the content of residual " zinc ", the content of moisture but also contains a large amount of protein fungus filaments and complicated chemical complex more than 80% in the dregs of a decoction, and it is thick to be oiliness.The technology that tradition is extracted " zinc " mostly is to utilize acid-base method, not only the operational path complexity, the production cycle is long, energy consumption is high but also very difficult filtration, removal of impurities, " zinc " product of producing contains harmful many, poor practicability of impurity.Owing to the effect of highly basic, strong acid, the filter residue after the filtration, filtrate are again very big source of pollution in addition.For example: on October 19th, 1994 was " producing the method and the combustion equipment of zinc sulfate with producing the erythromycin waste residue " patent of invention of CN1093681A by the disclosed publication number of State Intellectual Property Office, this method is earlier the cold of dregs of a decoction nature to be shone to leather hard, again by a kind of special roasting kiln with coal or other fuel to the dregs of a decoction heat, heating flame, therefrom reclaim zinc oxide and produce the way of zinc sulfate with sulfuric acid reaction.Though this invention has solved the resource utilization of the dregs of a decoction and used, because the energy consumption that produces is big in process of production, cost is high, run into can't produce again in rainy season or winter, and residual sour waste residue, waste liquid after filtering have polluted environment again.Because no obvious social and economic benefit be not so obtain promotion and application for many years always.And for example the number of patent application that on May 11st, 2005, State Intellectual Property Office announced is " treatment process that contains zinc antibiotic bacterium slag " patent of invention of 200310108527.8, this method be utilize hydrochloric acid, sulfuric acid or acetic acid and water with the dregs of a decoction dilution of alkalescence, transfer to acidity, then with the metallic zinc in the chelating ion exchange resin absorption dregs of a decoction, with heavy dose of acid or hydrochlorate the zinc in the exchange resin is broken away from again, finish separating of zinc and the dregs of a decoction, use with the resource utilization that realizes the dregs of a decoction.But because this method has been utilized a large amount of acid supplements and water resources, the pollution of discharging is not sayed and is spoken.The more important thing is heavy dose of acid supplement and adopt expensive ion exchange resin to be used for waste dregs generated processing, production cost is well imagined.So the resource utilization of erythromycin waste residue or antibiotic bacterium dregs, harmless treatment and application are still problem anxious to be solved at present.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art and defective, the method that a kind of technology is simple, production cost is low, the synthesization of environmentally safe utilizes erythromycin waste residue to reclaim zinc and produce Yeast protein with the erythromycin waste residue after the dezincify is provided.
For realizing purpose of the present invention, the technical scheme that is adopted is: a kind of method that reclaims the zinc in the erythromycin waste residue and produce Yeast protein with the erythromycin waste residue after the dezincify, this method comprises the following steps:
A. the erythromycin waste residue that will wet is packed in the reactor of belt stirrer, measures the wherein content of zinc simultaneously;
B. extraction agent is put in the aforesaid reaction vessel, the extraction agent input amount is 4 by the ratio of the weight of zinc content in the reactor and extraction agent: 0.5-2, and temperature of reaction is 15-30 ℃, reaction times 2-3 hour;
C. reacted material is carried out solid-liquid separation;
D. the solution after separating is hydrolyzed or electrolysis, directly gets zinc powder after the electrolysis;
E. the dregs of a decoction after separating can be directly used in protein fodder maybe with after this dregs of a decoction sterilization, and the inoculation yeast bacterial classification ferments, and produces Yeast protein.
During above-mentioned process using hydrolysis, hydrolysis time is 30-40 minute, and temperature is 50-60 ℃, cools off, filters, dries, calcines after hydrolysis is finished, and promptly gets the active oxidation zinc powder;
The temperature of above-mentioned calcining heating is 500-800 ℃, and calcination time is 1-3 hour.
Above-mentioned solid-liquid separation is to adopt plate basket filter to carry out solid-liquid separation.
Above-mentioned extraction agent by weight percent concentration be the industrial ammonia of 20-30% and agricultural Ammonium bicarbonate food grade or urea by 1: the 0.1-0.08 mixed forms.
Above-mentioned leavening temperature is 25-40 ℃, and fermentation time is 24-48 hour.
Characteristics of the present invention are: 1, production unit and technology are simple.Adopt technical scheme of the present invention in process of production, the equipment that uses need not specific equipment as reactor and conventional filtration equipment that conventional belt stirs, and the control of the technological process of production and simple to operate; 2, production cost is low.The technical program in extracting the process of zinc, desired raw material cheap, production cost is very low.The selling price of the zinc oxide that extracts from erythromycin waste residue per ton just can be regained the production cost in the leaching process of erythromycin waste residue per ton, and the dregs of a decoction behind the extraction zinc oxide are profit as high protein feed post sales.3, the technical program again can be with its effective ways that use as high protein feed for harmless treatment with utilize erythromycin waste residue that a kind of environment of both having protected is provided.
