specific Embodiment approach 1

[0022] Specific embodiment one: a kind of method of utilizing polypeptide antibiotic bacterium slag of the present embodiment to produce organic fertilizer, it is carried out according to the following steps:

[0023] 1. Collect fresh polypeptide antibiotic residues, add water to adjust the moisture content to 80% to 90%, and obtain bacterial residues to be treated;

[0024] 2. Add persulfate as an oxidizing agent to the bacterial residue treated in step 1, and mix well; wherein, the molar ratio of the residual antibiotic in the polypeptide antibiotic bacterial residue to persulfate is 1:40-70;

[0025] 3. Put the fungus residue treated in step 2 in a water bath at 70-95°C, and oxidize it for 0.3-1.0 hours;

[0026] 4. Cool the bacterial residue after the completion of the trioxidation reaction to room temperature, centrifuge it for 20 minutes at a speed of 4000-8000r / min, mix the obtained bacterial residue with humic acid or bentonite as auxiliary material, stir, dry and gran...

Abstract

The invention provides a method for preparing organic fertilizer from polypeptide antibiotic bacteria residues and relates to a harmless treatment and resource utilization method for the polypeptide antibiotic bacteria residues in order to solve the problems that treatment cost of existing polypeptide antibiotic bacteria residues is high, environmental risks still exist after treatment of the existing polypeptide antibiotic bacteria residues and the like. The method comprises steps as follows: fresh polypeptide antibiotic bacteria residues are subjected to oxidation treatment by utilizing persulfate as an oxidizing agent, wherein the residual quantity of polypeptide antibiotics in the fresh polypeptide antibiotic bacteria residues is 800-1500 mg / kg, and pH is 6.5-8.0; the treated bacteria residues are subjected to centrifugal treatment and then subjected to mixed granulation with auxiliary materials, and the organic fertilizer is prepared. The fertilizer preparation technology is simple, easy to operate and low in treatment cost; polypeptide antibiotic degradation efficiency is high, polypeptide antibiotic resistant bacteria in the bacteria residues can be effectively killed, and use safety of the fertilizer is high; one safe treatment and resource utilization method for the bacteria residues is provided for a pharmaceutical enterprise, and certain economic benefit is achieved by the enterprise through reduction of the treatment cost.

Description

technical field [0001] The invention relates to a harmless treatment and resource utilization method of polypeptide antibiotic bacteria residues. Background technique [0002] my country is a major producer of antibiotics. In 2011, my country's antibiotic output was 1.116 million tons, accounting for more than 70% of the global market. The production of antibiotics is mainly based on fermentation, and about 8-10t of wet fungus residue is produced for every 1t of antibiotics produced. Antibiotic residues are rich in nutrients, but because they contain a small amount of antibiotic residues, in order to prevent the risk of bacterial resistance caused by antibiotic residues in the environment, antibiotic residues must first be treated to remove antibiotic residues before they can be used. If not handled properly, it will seriously endanger the ecological environment and human health. In 2008, antibiotic residues were included in the newly revised "National Hazardous Waste List...
