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 biological medicine waste residues. The method comprises the following steps that (1) an activating agent is added into the biological medicine waste residues containing the penicillin antibiotics, size mixing and dispersing are carried out, then waste residue slurry is obtained; and (2) a catalyst and an oxidizing agent are added into the waste residue slurry obtained in the step (1), and after the degradation reaction, the residual penicillin antibiotics in the biological medicine waste residues is removed. Compared with the prior art, the residual antibiotics can be rapidly and efficiently removed by 99% and more by the method, moreover, the penicillin antibiotics is degraded into other substances which are non-toxic and have no pesticide effect, the obtained waste residues are solid, is convenient to store and transport, and can be applied to production of fertilizers and soil conditioners, the development concept of green coordination and sustainable development is met, and the requirements of energy conservation and environmental protection advocated by China are met.

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...
