specific Embodiment approach 1

[0023] Specific embodiment one: a kind of method of utilizing aminoglycoside antibiotic scum to produce organic fertilizer of the present embodiment, it is to carry out according to the following steps:

[0024] 1. Collect fresh aminoglycoside antibiotic residues, add water to adjust the moisture content to 80-90%, and obtain the residues to be treated;

[0025] Two, add persulfate as oxidizing agent, hydrogen peroxide as auxiliary oxidizing agent respectively in the bacterium slag processed through step 1, mix; Wherein, the mol ratio of aminoglycoside antibiotics and persulfate radical and hydrogen peroxide in bacterium slag is 1:30~70:3;

[0026] 3. Place the fungus residue treated in step 2 in a water bath at 65-95°C, and oxidize it for 0.4-0.8 hours under ultraviolet conditions with a wavelength of 200-400nm;

[0027] 4. After the oxidation treatment, the bacterial residue is cooled to room temperature, centrifuged for 20 minutes at a speed of 4000-8000r / min, and the obta...

specific Embodiment approach 2

[0029] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the persulfate is potassium persulfate or ammonium persulfate. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0030] Embodiment 3: This embodiment is different from Embodiment 1 in that: add water to adjust the moisture content to 85-90%. Others are the same as in the first embodiment.

Abstract

The invention discloses a method for preparing organic fertilizer by use of aminoglycoside antibiotic mushroom dregs, relates to a harmless treatment and resourceful utilization method of the aminoglycoside antibiotic mushroom dregs and aims to solve the problems that a technology for effectively treating aminoglycoside antibiotic mushroom dregs is still absent at present, the treatment effect is poor, the high-concentration aminoglycoside antibiotic mushroom dregs cannot be treated, the treatment cost is high, environmental risks still exist after treatment, treated mushroom dregs cannot be effectively utilized and the like. The mushroom dregs with the residual quantity of aminoglycoside antibiotics being 1,000-2,000 mg/kg are jointly treated by use of persulfate and hydrogen peroxide in cooperation with ultraviolet radiation, and the organic fertilizer is prepared from the treated mushroom dregs. The removal efficiency of aminoglycoside antibiotics is up to 99.6%, the sterilization capability is high, the treatment cycle is short, and treatment cannot completed within 1 hour.

Description

technical field [0001] The invention relates to a harmless treatment and resource utilization method of aminoglycoside antibiotic bacteria residues. Background technique [0002] my country is a major producer of antibiotics. In 2011, the output of antibiotics in my country was 1.116 million tons, accounting for more than 70% of the global market, of which the annual output of aminoglycoside antibiotics was about 2,000 tons. According to the estimate of 8-10 tons of wet bacteria residues produced per 1 ton of antibiotics, the annual production of aminoglycoside antibiotics bacteria residues in my country is about 16,000 to 20,000 tons. Bacterial residues are rich in nutrients, but because they contain a small amount of antibiotic residues, in order to prevent the risk of bacterial resistance in the environment caused by antibiotic residues, antibiotic residues must first be treated to remove antibiotic residues before they can be used. If not handled properly, it will serio...
