Embodiment 1

[0031] Penicillin content is 5800ppm waste residue. Add 93g water, 20g sulfuric acid in 20g waste residue, form the slurry that solid content is 15%; Add 2g catalyst FeSO in the slurry afterwards 4 ·7H 2 O, 6g of oxidant hydrogen peroxide, reacted at 70°C under normal pressure for 3 hours; after separation and drying, 15.14g of a product with a solid content of 70% was obtained, the residual amount of penicillin was detected to be less than 10ppm, and the removal rate reached more than 99%.

Embodiment 2

[0033] The penicillin content is the waste residue of 3812ppm. Add 450g water, 0.5g nitric acid in 50g waste residue, form the slurry that solid content is 10%; Add 0.03g catalyst FeCl in the slurry afterwards 2 , 45g of hypochlorous acid as an oxidant, reacted at 60°C and normal pressure for 2.5 hours; after separation and drying, 32.35g of a product with a solid content of 85% was obtained, and the residual amount of penicillin was detected to be less than 10ppm, and the removal rate reached more than 99%. .

Embodiment 3

[0035] The waste residue with 6-aminopenicillinic acid content of 5000ppm. In 500g waste residue, add 1900g water, 100g sulfuric acid, form the slurry that solid content is 20%; Add 20g catalyst MnCl in slurry afterwards 2 4H 2 O, oxidant potassium permanganate 50g, reacted at 90 ℃ and normal pressure for 1 hour; through separation and drying, the product 333.8g with a solid content of 75% was obtained, and the residual amount of penicillin was detected to be less than 10ppm, and the removal rate reached 99% %above.

Abstract

The invention relates to a method for removing residual penicillin antibiotics in biomedical waste residues, comprising the following steps: (1) adding an activator to the biomedical waste residues containing penicillin antibiotics, and obtaining waste residue slurry after slurry mixing and dispersion; 2) Adding a catalyst and an oxidizing agent to the waste residue slurry obtained in step (1), and performing a degradation reaction to complete the removal of the residual penicillin antibiotics in the biomedical waste residue. Compared with the prior art, the present invention can quickly and efficiently remove more than 99% of residual antibiotics, and this method degrades penicillin antibiotics into other non-toxic and non-medicinal substances, and the waste residue obtained from the treatment is solid, which is convenient for storage It can be used for the production of fertilizers and soil conditioners, which conforms to the concept of green, coordinated and sustainable development, and meets the requirements of energy conservation and environmental protection advocated by the state.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method for removing residual penicillin antibiotics in biomedical waste residues. Background technique [0002] my country is the world's largest producer and exporter of antibiotic raw materials, producing more than 70 kinds of antibiotics, accounting for 70% of the global production, of which penicillin industrial salt accounts for 75% of the global production. According to statistics, hundreds of thousands of tons of penicillin waste residues need to be processed every year. [0003] Biomedical fermentation waste residues contain residual antibiotics, if not treated, it will cause secondary fermentation, produce stench, and pollute the environment; residual antibiotics will enter the environment, leading to the emergence of microbial resistance, especially pathogenic bacteria and conditional pathogens Antibiotic resistance in bacteria is increasing, which greatly hin...
