Method for preparing organic fertilizer from lincomycin fungi residues

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 ...

AI Technical Summary

Problems solved by technology

[0006] In view of the fact that there is no safe and effective treatment method for lincomycin residues in my country at present, there is an urgent need for a technology that can treat antibiotic residues in order to realize the harmless treatment and safe utilization of antibiotic residues
