specific Embodiment approach 1

[0024] Specific embodiment one: a kind of method of utilizing antibiotic scum to produce organic fertilizer of the present embodiment is characterized in that it is carried out according to the following steps:

[0025] 1. Collect antibiotic slag, adjust the solid content to 8-10%, and obtain the slag liquid to be treated. Take 1L of the slag liquid to be treated, add percarbonate in the reaction tank, and stir to mix evenly;

[0026] 2. Heat the antibiotic bacteria residue reaction tank containing percarbonate to 60-80°C, and keep it warm for 2 hours under uniform stirring;

[0027] 3. After the reaction is completed, the bacterial residue is centrifuged, and the obtained bacterial residue precipitate is mixed with humic acid or bentonite as an auxiliary material, stirred, dried and granulated to make organic fertilizer;

[0028] The residual amount of antibiotics in the antibiotic bacteria residue liquid is 600-700 mg / L, pH=4.0-7.8;

[0029] The molar ratio of antibiotic to...

specific Embodiment approach 2

[0031] Embodiment 2: This embodiment differs from Embodiment 1 in that the molar ratio of the antibiotic to percarbonate is 1:300-400. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0032] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the molar ratio of the antibiotic to percarbonate is 1:400-500:1. Others are the same as in the first embodiment.

Abstract

The invention discloses a method for treating antibiotic fungi residues by percarbonate to prepare an organic fertilizer, relates to a treating method and recycling for antibiotic fungi residues and aims at solving the problems that existing antibiotic fungi residue treatment cost is high, has environmental risk after treatment and the like. The method disclosed by the invention comprises the steps of adding percarbonate into antibiotic fungi residue liquid, putting in a reaction tank, heating to 60 to 80 DEG C, performing thermal-insulation reaction and centrifuging to collect precipitate toprepare the organic fertilizer, wherein the molar ratio of antibiotic to percarbonate is 1 to (300 to 500). By means of the method disclosed by the invention antibiotic residues can be degraded in high efficiency, and antibiotic drug resistance bacteria contained in the fungi residues are inactivated; furthermore, a pH need not be adjusted after treatment, and method procedures are simple. The method disclosed by the invention has the advantages of relatively moderate harmless treatment condition, lower reaction temperature requirement, ability in preventing protein denaturation, high safety,high efficiency and low cost. The fungi residue organic fertilizer does not contain the antibiotic drug resistance bacteria, cannot generate bacterium drug resistance in soil and has high use safety.

Description

technical field [0001] The invention relates to a harmless treatment method and resource utilization of antibiotic bacteria residues. 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 se...
