specific Embodiment approach 1

[0029] Specific embodiment one: a kind of method of utilizing tylosin slag to prepare organic fertilizer of the present embodiment, it is carried out according to the following steps:

[0030] 1. Collect fresh tylosin slag, add water to adjust the moisture content to 85-90%, and obtain the slag to be treated;

[0031] 2. Add persulfate and copper sulfate to the bacterial residue treated in step 1 respectively, and mix well; the molar ratio of tylosin to persulfate and copper ion in the bacterial residue is 1:40~60:0.4;

[0032] 3. Place the bacterial residue treated in step 2 in a water bath at 60 to 90°C, and conduct oxidation treatment for 0.5 to 1.0 h;

[0033] 4. Cool the oxidized tylosin bacterial residue to room temperature, centrifuge for 20 min under the condition of a rotating speed of 4000-8000 r / min, and mix the obtained bacterial residue precipitate with auxiliary humic acid or bentonite, stir and dry to make granules, that is, the described utilization of tylosin...

specific Embodiment approach 2

[0035] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the molar ratio of tylosin to persulfate and copper ions is 1:45 to 60:0.4. Others are the same as the first embodiment.

specific Embodiment approach 3

[0036] Embodiment 3: This embodiment is different from Embodiment 1 in that the molar ratio of tylosin to persulfate and copper ions is 1:45 to 55:0.4. Others are the same as the first embodiment.

Abstract

The invention discloses a method for preparing organic fertilizer from tylosin dregs, relates to a method for harmless treatment and resourceful utilization of tylosin dregs and aims to solve the problems that existing tylosin dregs are high in treatment cost, environmental risks still exist after treatment and the like. Tylosin dregs are mixed with persulfate and copper sulfate, the mixture is heated in a water bath, oxidized and centrifuged, the mushroom dregs are collected, and the organic fertilizer is prepared. The removal efficiency of persulfate for tylosin dregs is up to 99.9%, the sterilization capability is high, the treatment cycle is short, and treatment can be completed within 0.5-1.0 h.

Description

technical field [0001] The invention relates to a method for harmless treatment and resource utilization of tylosin bacterial residue. Background technique [0002] my country is a big country in the production, use and export of antibiotics. In the production process of fermented antibiotics in my country, the annual discharge of bacterial residues is about 2 million tons. Antibiotic residues lead to the risk of bacterial resistance in the environment, and antibiotic residues must be treated to remove antibiotic residues before they can be used. But so far, there is still no safe and effective method for harmless and resourceful treatment of antibiotic bacteria residues in my country. At the same time, the high cost of bacterial residue treatment seriously affects the healthy development of the pharmaceutical industry. [0003] Tylosin is a macrolide antibiotic specially used for anti-infection and growth-promoting livestock and poultry. It has been widely used in many cou...
