Description

technical field [0001] The invention belongs to the field of waste recycling and regeneration, and in particular relates to a preparation method of a porous carbon-based composite material. Background technique [0002] As a typical example of organic waste, antibiotic residues produce nearly 10 million tons per year in my country, which not only takes up storage space, but also pollutes the environment. Some researchers try to recycle bacteria residues in feed and chemical fertilizers. However, there are various safety hazards in practical applications. For example, it is easy to cause drug resistance when used in feed. After antibiotics enter the soil, a series of transformation processes such as adsorption, migration, and degradation will occur. These transformation processes will induce microorganisms to produce resistance genes and change the diversity of soil microorganisms. water into the surface water poses a great threat to ecosystems.

[0002] As a typical example of organic waste, antibiotic residues have an annual output of nearly 10 million tons, which not only takes up space for storage, but also pollutes the environment

Some researchers try to recycle bacteria residues in feed and chemical fertilizers. However, there are various safety hazards in practical applications. For example, it is easy to cause drug resistance when used in feed. After antibiotics enter the soil, a series of transformation processes such as adsorption, migration, and degradation will occur. These transformation processes will induce microorganisms to produce resistance genes and change the diversity of soil microorganisms. Influx of surface waters is a huge threat to ecosystems

Chinese patent CN 108500034A discloses a process for treating antibiotic slag, which realizes the harmless treatment of slag through hydrothermal oxidation treatment. The preparation process of this scheme is complicated and the production cost is high

However, in the current research, activation and compounding are often carried out separately, which often results in time-consuming and labor-intensive phenomena.
