specific Embodiment approach 1

[0017] Specific embodiment one: a kind of pretreatment method that improves the anaerobic biogas production capacity of penicillin slag described in this embodiment is specifically carried out according to the following steps:

[0018] 1. Take the dehydrated penicillin residue from a pharmaceutical factory that produces antibiotics, then add distilled water and stir evenly to obtain fermentation raw materials, put the fermentation raw materials in a microwave oven, digest them at a temperature of 100°C to 105°C for 55s to 65s, and cool to Room temperature, obtain the penicillin slag after digestion;

[0019] The volume ratio of the quality of penicillin scum after dehydration in the pharmaceutical factory producing antibiotics to distilled water is 1g:(0.2~0.5)mL;

[0020] The water content in the dehydrated penicillin slag of the pharmaceutical factory producing antibiotics is 72.0% to 78.0%, the solid content is 22.0% to 28.0%, and the mass percentage of C in the solid is 45...

specific Embodiment approach 2

[0029] Embodiment 2: This embodiment differs from Embodiment 1 in that: the penicillin slag after dehydration in the pharmaceutical factory producing antibiotics described in step 1 has a water content of 75.0% and a solid content of 25.0%. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0030] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the mass percentage of C in the solid described in step 1 is 47.0%, the mass percentage of N is 10.5%, H The mass percentage content is 7.1%, and the penicillin residue is 2.1mg / g. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a pretreatment method for improving anaerobic biogas-production by penicillin slag, and mainly solves the problem that conventional penicillin slag contains a lot of mycelia and a little penicillin residues which inhibit anaerobic digestion to reduce the biogas output. The method comprises the following steps: I, taking dehydrated penicillin slag of a pharmaceutical factory producing antibiotics, then adding distilled water and uniformly stirring to obtain a fermenting raw material, putting the fermenting raw material in a microwave oven, decomposing the fermenting raw material at a high temperature to obtain the decomposed penicillin slag; II, uniformly mixing the decomposed penicillin slag with anaerobic sludge to obtain a mixed liquid and adjusting the pH value and the C/N of the mixed liquid to obtain a fermenting liquid, that is, pretreatment for improving anaerobic biogas-production by penicillin slag is realized. The invention is used for pretreatment method for improving anaerobic biogas-production by penicillin slag.

Description

technical field [0001] The invention relates to a pretreatment method for increasing the anaerobic biogas production of penicillin slag, and belongs to the fields of biotechnology, new energy, green chemical technology, environmental protection and the like. Background technique [0002] Penicillin residues are wastes produced during the production process of antibiotic production enterprises. Because they contain a certain amount of antibiotic residues, they are listed as hazardous wastes by relevant state departments. Unreasonable treatment methods can easily cause environmental pollution and ecological hazards. At the same time It will also cause waste of resources. At present, the treatment of penicillin residues has become an important factor restricting the development of antibiotic production enterprises. How to degrade the antibiotic residues in the bacteria residue and make them into resources has become an urgent problem for antibiotic production enterprises to so...
