Abstract

The invention provides a method and equipment for treating antibiotic mycelium residues. According to the method, the antibiotic mycelium residues and water are prepared into a mycelium residue suspension which is subjected to anaerobic fermentation treatment. The invention also provides the equipment for treating the antibiotic mycelium residues, and the equipment comprises a residue water generating device, an anaerobic fermentation device, a gas-liquid separation device positioned above the anaerobic fermentation device, a biogas collection device positioned above the gas-liquid separation device and a riser pipe for communicating the gas-liquid separation device and the anaerobic fermentation device. By using the method and equipment for treating the antibiotic mycelium residues, the mycelium residue suspension obtained after the mixing of the antibiotic mycelium residues and the water is subjected to anaerobic fermentation treatment, so that the inhibition of harmful substances of anaerobic fermentation antibiotics and the like in the conventional antibiotic mycelium residues is overcome, the amount of preponderant bacteria is kept to the utmost extent, the efficiency of anaerobic fermentation is improved, and the method and the equipment have the advantages of small floor area, simple operation, low cost and the like.

Description

technical field [0001] The invention relates to a treatment method and equipment for antibiotic scum, which performs anaerobic fermentation treatment on a mixture of antibiotic slag and water, and belongs to the field of antibiotic treatment. Background technique [0002] Antibiotic residue is an inevitable product in the production process of the fermentation pharmaceutical industry. With the rapid development of the pharmaceutical industry, the output of antibiotic residues is also increasing. Bacterial residues are rich in protein. It was not until the 1950s that people began to realize the need to utilize the rich resources of antibiotic residues. However, from this beginning to the beginning of the 21st century, the application of antibiotic bacteria residues only stayed in the protein feed or additive field of aquaculture. [0003] Before 2002, scholars focused on the reduction of antibiotic potency in the study of fungal residue, and did not evaluate the possible da...
