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.
