Problems solved by technology

If it is not treated in time, it will cause secondary fermentation and cause more serious environmental pollution. If it is only treated in a general way, it will cause a large amount of organic matter and trace elements such as nitrogen and phosphorus in the fungus residue to be lost in vain, resulting in waste of resources.

Embodiment 1

[0018] Take 10L erythromycin residue, detect erythromycin residue 274mg / ml, pH6.5. After washing the membrane, add nitric acid water to adjust the pH value to 3.3, heat and boil for 1 hour. The residual erythromycin was 5.6mg / Kg, and the organic matter was 14.11%. Add 5L of tetracycline urea double salt mother liquor dialysate (organic matter 3.76%, dry matter 33.86%, total nitrogen 16.83%, PH6.09) separated by an organic membrane with a molecular weight of 100-600, stir evenly, and then add ammonium humate 0.8Kg, bentonite 1.5Kg mixed. After passing the test, it is sprayed and granulated, dried until the moisture content is less than or equal to 20%, screened, and the finished product is packaged.

[0019]

Embodiment 2

[0021] Take 10L erythromycin residue, erythromycin residue 281mg / ml, pH6.62. After washing the membrane, add nitric acid water to adjust the pH value to 2.8, heat and boil for 2 hours. The residual erythromycin was 4.7mg / Kg, and the organic matter was 15.02%. Add 5L of tetracycline urea double salt mother liquor dialysate (organic matter 3.76%, dry matter 33.86%, total nitrogen 16.83%, PH6.09) separated by an organic membrane with a molecular weight of 100-600, stir evenly, and then add ammonium humate 1.2Kg, bentonite 1.8Kg mixed. After passing the test, it is sprayed and granulated, dried until the moisture content is less than or equal to 20%, screened, and the finished product is packaged.

[0022]

Embodiment 3

[0024] Take 15L erythromycin residue, erythromycin residue 260mg / ml, pH6.48. After washing the membrane, add nitric acid water to adjust the pH value to 3.5, heat and boil for 1 hour. The residual erythromycin was 4.4mg / Kg, and the organic matter was 10.74%. Add 5L of tetracycline urea double salt mother liquor dialysate (organic matter 3.76%, dry matter 33.86%, total nitrogen 16.83%, PH6.09) separated by an organic membrane with a molecular weight of 100-600, stir evenly, and then add ammonium humate 2.0Kg, bentonite 3Kg mixed. After passing the test, it is sprayed and granulated, dried until the moisture content is less than or equal to 20%, screened, and the finished product is packaged.

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 [0001] The invention relates to the technical field of biology and medicine, in particular to a method for producing organic fertilizer by using erythromycin residue and tetracycline urea double salt mother liquor. Background technique [0002] Over the years, due to the long-term use of chemical fertilizers and insufficient organic fertilizers in my country's agriculture, the soil structure has been destroyed, the proportion of various nutrients has been out of balance, and the ecological environment has also been polluted to a certain extent. On the other hand, organic agriculture uses organic fertilizers instead of chemical fertilizers in agricultural production, and at the same time implements the crop rotation system, which can protect the ecological environment, improve soil structure, increase soil fertility, and improve the quality of agricultural products. Therefore, the development of organic agriculture is a new type of agriculture that produces gr...
