Problems solved by technology

According to investigations, the amount of penicillin residue produced by each pharmaceutical company that produces penicillin drugs ranges from tens of thousands to hundreds of thousands of tons every year. The large amount has caused great difficulties in the treatment of penicillin residues.
The "National Hazardous Waste List" revised after 2008 defines it as hazardous waste and requires it to be incinerated. However, due to the high cost of incineration, it is easy to cause secondary pollution. The incineration of vitamins and growth factors is a great waste of resources. Therefore, the development of new technologies for the quantification and harmless treatment of penicillin residues has become an urgent problem for penicillin manufacturers.
[0003]Patent CN201310095896.1 discloses a method of treating penicillin residues by using thermal hydrolysis and anaerobic digestion process. 15-25 hours of solid-liquid separation, the treatment efficiency is not high, and there is still 0.5mg / kg of penicillin residue after treatment, and the complete reduction of penicillin cannot be achieved
Patent CN201510094833.3 discloses a pretreatment method using ultrasonic crushing technology to increase the anaerobic biogas production of penicillin slag. In this method, the dehydrated penicillin slag is mixed with distilled water for ultrasonic treatment, which requires pre-dehydration treatment and preparation of distilled water. The process operation is complicated, and this method only discloses an anaerobic pretreatment method, which fails to realize the reduction and harmlessness of penicillin residue

Abstract

The invention provides a resourceful treatment method for penicillin fungi residues, wherein fungi residues produced during production of penicillin can be treated by adopting the steps of steam inactivation, enhanced pretreatment, mixing and blending, fungi residue blending, anaerobic co-digestion, concentrating and dewatering and the like. According to the invention, a treatment method low in energy consumption, high in efficiency and steady and reliable in effect is adopted, and drug residues in the penicillin fungi residues can be completely removed, thus realizing reduction and harmless treatment of the penicillin fungi residues.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to a method for recycling penicillin bacteria residues. Background technique [0002] Penicillin is the first antibiotic discovered in human history, and it is widely used. Its successful development has greatly enhanced the ability of humans to resist bacterial infections and led to the birth of the antibiotic family. Penicillin antibiotics are a general term for a large class of antibiotics in β-lactams. Since β-lactams act on the cell wall of bacteria, while humans only have cell membranes without cell walls, penicillin antibiotics have very little toxicity and are antibiotics with the largest chemotherapy index. . my country is a big penicillin producing country. The solid waste produced in the production process of penicillin is penicillin residue. Degradation products, flocculants, acidifiers, filter aids, residual organic solvents, residual antibiotics and m...
