TECHNICAL FIELD

[0001] The utility model relates to the technical field of breeding wastewater treatment, specifically for a kind of biological carbon adsorption and regeneration system for breeding wastewater treatment. BACKGROUND

[0002] Breeding wastewater refers to the wastewater generated during breeding, which contains high organic matter, high ammonia nitrogen, suspended solids, and possibly antibiotics and heavy metals. Generally, the treatment methods for breeding wastewater include physical, chemical, biological and ecological treatment. Among them, the use of biochar for breeding wastewater treatment is also relatively common. The raw materials for making biochar are agricultural waste (straw, rice husk), sawdust, animal manure and other biomass. Preparation: anaerobic pyrolysis (300-800℃), product contains high carbon content (60%-90%), specific surface area can reach 500-2000 m² / g. Surface properties: rich in carboxyl, hydroxyl, phenolic hydroxyl and other functional groups, with negative charge;

[0003] The adsorption mechanism of biochar for breeding wastewater adsorption is: physical adsorption: pore filling (mainly micropore <2nm) and van der waals force. Chemical adsorption: complex between functional groups and pollutants, ion exchange (such as heavy metals Hg²⁺, Pb²⁺). Electrostatic adsorption: negatively charged biochar adsorbs cationic pollutants (such as Cr 6 ⁺, dye molecules).

[0004] Currently, when using biochar to treat breeding wastewater, it is not possible to recycle the biochar, resulting in waste of biochar carbon source after the first treatment of breeding wastewater by biochar, which is not conducive to cost savings for breeding wastewater treatment.
