Problems solved by technology

Incineration not only increases the treatment cost of antibiotic fermentation residue, but also causes waste of resources. Therefore, it is necessary to study the harmless treatment method of antibiotic fermentation residue to remove the residual antibiotics in antibiotic fermentation residue, so as to become a fertilizer for antibiotic fermentation residue Resource Utilization Creates Conditions

Embodiment 1

[0061] Mix 60 tons of penicillin fermented bacteria residue with water and mix evenly to make 100m 3 suspension, add 30% peracetic acid 1m 3 , stirred and reacted for 1 hour, and stood still for 7 hours, the pH of the bacteria residue liquid was 2, and the pH was adjusted to 6 with ammonia water. After adding the coagulation filter aid, it was filtered with a filter press to obtain a wet filter cake of bacteria residue with a water content of 77%. The slag-wet filter cake was dried at 90° C. for 120 minutes with a paddle-type continuous dryer to obtain 10.2 tons of dried fungus slag.

[0062] The test results of dry bacteria residue are as follows:

[0063] (1) Penicillin residues were not detected by liquid phase method and liquid mass method.

[0064] (2) Single-dose toxicity test by intragastric administration in mice, no obvious systemic toxic reaction was observed for 14 consecutive days.

Embodiment 2

[0068] Mix 60 tons of penicillin fermented bacteria residue with water and mix evenly to make 100m 3 suspension, add 30% peracetic acid 0.7m 3 , stirred and reacted for 1 hour, and stood still for 11 hours. The pH of the bacteria residue liquid was 3, and the pH was adjusted to 7 with ammonia water. The slag-wet filter cake was dried at 100° C. for 60 minutes with a paddle-type continuous dryer to obtain 9.1 tons of dried fungus slag.

[0069] The test results of dry bacteria residue are as follows:

[0070] (1) Penicillin residues were not detected by liquid phase method and liquid mass method.

[0071] (2) Single-dose toxicity test by intragastric administration in mice, no obvious systemic toxic reaction was observed for 14 consecutive days.

Embodiment 3

[0075] Mix 60 tons of penicillin fermented bacteria residue with 20 tons of water and 20 tons of biodiesel and mix evenly to make 100m 3 suspension, add 30% hydrogen peroxide 1m 3 , stirring and reacting for 1 hour, and standing for 7 hours, the pH of the bacteria residue liquid was 2, and the pH was adjusted to 7 with ammonia water. The slag-wet filter cake was dried at 90° C. for 120 minutes with a paddle-type continuous dryer to obtain 11.6 tons of dried fungus slag.

Abstract

The invention discloses a harmless treatment method of antibiotic fermented mushroom residues for manufacturing an organic fertilizer. The method comprises the following steps: a, adding water into fermented mushroom residues to stir and uniformly mix and chemically detoxifying the mixture with an oxidizing agent; b, adjusting the pH of a fermented mushroom residue liquid which is oxidized to 6-8 with alkali; and c, filtering and drying the fermented mushroom residue liquid to obtain dry fermented mushroom residues. The antibiotic fermented mushroom residues are treated by virtue of a chemical oxidation detoxifying technology, so that antibiotics in mushroom residues are free of residues, and the degradation rate reaches 100%, and harmless treatment is realized. The mushroom residues are used for manufacturing an organic fertilizer according to an organic fertilizer standard, so that resource utilization can be realized.

Description

technical field [0001] The invention belongs to the comprehensive technical field of antibiotic fermentation slag treatment, in particular to a harmless treatment method for antibiotic fermentation slag that can be used to manufacture organic fertilizers. Background technique [0002] Among the organic solid wastes in my country's pharmaceutical industry, the treatment of antibiotic fermentation residues is the most serious problem. The main components of antibiotic fermentation residues are the mycelium of antibiotic-producing bacteria, unused medium, and metabolic waste produced during fermentation. Products, degradation products of the medium, and residual antibiotics, etc. According to the "National Hazardous Waste List" revised in 2008, antibiotic fermentation residues belong to the culture medium waste in the production process of chemical raw materials and must be managed as hazardous waste. At present, the only legal disposal method for antibiotic fermentation residu...
