specific Embodiment approach 1

[0026] Specific embodiment one: a kind of method of utilizing lincomycin slag to produce organic fertilizer of the present embodiment, carries out according to the following steps:

[0027] 1. Collect fresh lincomycin residue, add deionized water to adjust the moisture content to 85-90%, and obtain the residue to be treated;

[0028] 2. Use a NaOH solution with a concentration of 5M to adjust the pH of the bacteria residue to 7-8;

[0029] 3. Add potassium persulfate and zinc acetate to the lincomycin residue after pH adjustment in step 2, and mix well; wherein, the molar ratio of lincomycin to persulfate and zinc is 1:22-26 : 0.8;

[0030] 4. Put the fungus residue treated in step 3 in a water bath at 80°C, and oxidize it for 0.3-1.0 hours;

[0031] 5. Cool the lincomycin slag after the reaction to room temperature, centrifuge it for 20 minutes at a rotational speed of 4000-8000r / min, dry and granulate the lincomycin residue to make organic fertilizer, that is, complete the...

specific Embodiment approach 2

[0032] Embodiment 2: This embodiment differs from Embodiment 1 in that fresh lincomycin residues are collected and deionized water is added to adjust the water content to 85-90% to obtain the residues to be treated. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0033] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the pH in step 2 is 7.5. Others are the same as in the first embodiment.

Abstract

The invention provides a method for preparing an organic fertilizer from lincomycin fungi residues, and relates to harmless treatment and recovery of the lincomycin fungi residues. The method provided by the invention aims at realizing the harmless treatment and resource utilization of the lincomycin fungi residues. The method concretely comprises the following steps of collecting fresh lincomycin fungi residues; regulating the moisture content and the pH value; adding potassium peroxydisulfate and zinc acetate for treatment; performing centrifugation and precipitate collection; manufacturing the organic fertilizer. The lincomycin residues are damaged and removed; antibiotic drug resistant bacteria in the fungi residues are inactivated. The method has the advantages that the process is simple; the operation is easy. The potassium peroxydisulfate is used; the removal rate on the lincomycin is high and reaches 99.9 percent; the treatment cost is low; the period is short; the operation can be completed in half an hour. The fungi residue organic fertilizer does not contain antibiotic drug resistant bacteria; bacterium drug resistance cannot be caused in the soil; the use safety is high.

Description

technical field [0001] The invention relates to the harmless treatment and resource utilization of lincomycin fungus residue. Background technique [0002] my country is a big country in the production, use and export of antibiotics. During the production process of fermented antibiotics in my country, the annual discharge of fungus residue is about 2 million tons. The fungus residue is rich in a large amount of nutrients, but because it contains a small amount of antibiotic residues, in order to prevent Antibiotic residues cause the risk of bacterial resistance in the environment. Antibiotic residues must first be treated to remove antibiotic residues before they can be used. But so far, there is still a lack of safe and effective harmless and resourceful treatment methods for antibiotic residues in my country, and most of them can only be incinerated, which not only causes a lot of waste of resources, but also has high cost of incineration, and there is a risk of secondary ...
