Abstract
The invention relates to a method for producing an organic fertilizer by using erythromycin waste residue and tetracycline urea double salt mother liquor. The method is characterized by comprising the following steps: evenly mixing erythromycin waste residue hydrolysate obtained by heating and hydrolyzing under an acid condition with dialysate of the tetracycline urea double salt mother liquor separated by an organic membrane in a manner of nanofiltration separation at a volume ratio of (2-3):1; then adding 5-10% of ammonium humate and 10-15% of bentonite based on total volume; evenly stirring, detecting that the total nutrient (N+P2O5+K2O) is greater than or equal to 2.0%, the organic matter is greater than or equal to 20% and the dry matter is greater than or equal to 35%; spraying and pelletilizing when the PH is 5.5-8.5, drying until the moisture is smaller than or equal to 20%, and sieving, so as to obtain the product, namely the organic fertilizer. By adopting the method, the organic fertilizer is prepared from the hydrolyzed erythromycin waste residue hydrolysate obtained by hydrolytic degradation and the dialysate of the tetracycline urea double salt mother liquor separated by the organic membrane by nanofiltration separation in a mixing manner, so that the problem of environmental pollution of antibiotic residues is ended; reutilization of resources is taken in; new economic benefits are brought about for enterprises; furthermore, the method is sufficient in raw materials, and low in manufacturing cost.
Description
Technical field
The present invention relates to biology and medical art, particularly relate to a kind of method of erythromycin bacterium slag and tetracycline urea double salt mother liquor production fertilizer.
Background technology
For many years, China's agricultural is due to life-time service chemical fertilizer, and fertilizer is not enough, causes Soil structure to destroy, and all kinds of nutritive props imbalance, ecotope is also subject to certain pollution.And Organic farming is that manure use material replaces chemical fertilizer in agriculture production, carries out arable land rotation system simultaneously, just can preserve the ecological environment, improve Soil structure, increase soil fertility, improve quality of agricultural product.Therefore, Development of Organic Agriculture is the emerging agricultural of producing green agricultural product.
In production of antibiotics technical field, the harmless treatment of waste residue is a difficult problem for puzzlement enterprise always.Such as, erythromycin bacterium slag and tetracycline urea double salt mother liquor, except containing except mycelium and a small amount of microbiotic in them, also containing the abundant trace element such as organic matter, nitrogen, phosphorus.If processed not in time, can Secondary Fermentation be caused, cause environmental pollution even more serious, and iff the general process of do, the loss in vain of a large amount of organic matter and the trace element such as nitrogen, phosphorus in bacterium slag can be caused again, cause the wasting of resources.Therefore how to deal carefully with antibiotic bacterium dregs, making it turn waste into wealth is ensure the normal production problem in urgent need to solve of enterprise.
Summary of the invention
The object of the present invention is to provide a kind of erythromycin bacterium slag and tetracycline urea double salt mother liquor to produce the method for fertilizer, the method achieves the recycling of resource while solving environmental pollution.
The technical solution used in the present invention is:
A kind of erythromycin bacterium slag and tetracycline urea double salt mother liquor produce the method for fertilizer, it is characterized in that: by the erythromycin bacterium slag hydrolyzed solution of heating hydrolysis gained in acid condition with mix according to the volume ratio of 2 ~ 3:1 through the dialyzate of the tetracycline urea double salt mother liquor of organic membrane nanofiltration separation gained, then the ammonium humate of 5 ~ 10% of cumulative volume, the wilkinite of 10 ~ 15% is added, stir, detect total nutrient (N+P
2o
5+ K
2o)>=2.0%, organic>=20%, dry-matter>=35%, spray granulating during PH5.5 ~ 8.5, dries to moisture≤20%, and screening obtains finished product fertilizer.
Described acidic conditions refers to pH value <4.0.
Described acidic conditions employing adds 2 ~ 5% nitric acid and washes film water realization.
Described heating hydrolysis refers to heated and boiled 1 ~ 2 hour.
The molecular weight 100 ~ 600 of described organic membrane.
The present invention has following technical characterstic:
1, adopt the method degraded erythromycin bacterium slag of heating hydrolysis under acidic conditions, thus greatly reduce erythromycin residual (being less than 10mg/Kg) in film slurry, and effective constituent is retained.
2, directly filter out with the method for organic membrane nanofiltration separation the tsiklomitsin that in tetracycline urea double salt mother liquor, major part is residual, large amount of organic is enriched in dialyzate.
3, add the improvement that ammonium humate is conducive to organic fertilizer product outward appearance and quality, wilkinite can increase dry-matter ratio, is conducive to the operation of spray granulating, reduces production cost simultaneously.
The present invention becomes fertilizer by above by hydrolytic deterioration gained erythromycin bacterium slag hydrolyzed solution with the tetracycline urea double salt mother liquor dialyzate mixing manufacture of gained after organic membrane nanofiltration separation, both the final result problem of environmental pollution of microbiotic waste residue, achieve again the recycling of resource, for enterprise brings new economic interests.And starting material of the present invention are sufficient, low cost of manufacture.
