▎ 摘　　要

NOVELTY - Nitrogen-doped biological carbon, where the nitrogen-doped bio-carbon surface is uniformly distributed with mesoporous structure and graphene-like structure of the pleat-shaped bump, the specific surface area, where the average hole diameter and the pore volume are respectively 630-1340 m2/g 20-45 nm and 0.3-0.6 cm3/g. USE - The nitrogen-doped biological carbon is useful for activating persulfate, especially peroxodisulfate, and it is used for adsorption and degradation of macromolecular organic pollutants. The catalytic degradation of macromolecular organic pollutants is achieved by activating peroxodisulfate (all claimed). ADVANTAGE - The nitrogen- doped bio-char can be activated by disulfate on the basis of biological carbon adsorption to remove pollutant, realizes catalytic degradation of the humic acid, tetracycline macromolecule organic pollutant, but also can be repeatedly used, and has good stability.
