Harmless treatment method for antibiotic mycelium residues

Abstract

The invention relates to a harmless treatment method for antibiotic mycelium residues. The treatment method comprises the steps of firstly, adding glucose, a microbial compound strain and grass meal into the antibiotic mycelium residues, mixing uniformly, and performing culture to prepare a solid fermentation strain; and secondly, mixing the strain, the grass meal and fresh antibiotic mycelium residues according to a weight ratio, and fermenting for 72-96 hours to obtain harmlessly fermented high-protein antibiotic mycelium residues. A mycelium residue fermentation product is dried, ground and screened by a 60-mesh sieve to obtain fermented high-protein mycelium powder. With the method, no polluted water is generated in the process, the fermentation product is free of antibiotic residues through detection with HPLC (High Performance Liquid Chromatography) and cylinder plate methods, secondary harmless wastes are not generated, the protein content of the harmlessly treated high-protein mycelium powder exceeds 30%, the equipment investment and the running cost are low, the effects of energy conservation and environmental protection are achieved, and the prepared high-protein mycelium powder can be further applied as a resource and has high environmental and economic benefits.

Description

technical field [0001] The invention relates to the fields of antibiotic fermentation and environmental protection, in particular to a harmless treatment method for antibiotic residues. Background technique [0002] my country is the world's largest producer and exporter of antibiotic raw materials, with an annual output of more than 200,000 tons. It is estimated that 8 to 10 tons of antibiotic residues are produced for every ton of antibiotics produced, and more than one million tons of antibiotic residues are discharged every year. In February 2002, the Ministry of Agriculture, the Ministry of Health, and the State Drug Administration announced No. 176 to include antibiotic residues in the catalog of drugs that are prohibited from being used in feed and animal drinking water. The "National Hazardous Waste List" revised in 2008 also stipulates that antibiotic residues must be managed as hazardous waste. With the development of antibiotic production and the gradual improvem...

AI Technical Summary

Problems solved by technology

With the development of antibiotic production and the gradual improvement of environmental protection requirements, the problem of bacterial residue treatment has become increasingly prominent. Some enterprises can only dry and seal the bacterial residue, which not only increases the occupied area, but also increases the possibility of secondary pollution and production costs. and environmental pressure greatly increased

Bacterial residue incineration or the use of sewage treatment systems or biogas fermentation can partially solve the problem of antibiotic pollution, but the equipment investment and operation costs are huge, and there is a risk of secondary pollution such as dioxins or biogas slurry

The existing treatment method also wastes the high-protein resources contained in the fungus residue, as long as the residual antibiotics contained in the potential environmental hazards are removed and the potential environmental risks are eliminated, the highly valuable high-protein resources can be prepared
