Description

Technical Field

[0001] The utility model relates to the technical field of biochar modification, and in particular to an intelligent device for physical modification of biochar. Background Art

[0002] Biochar is a solid material made by high-temperature thermal cracking of waste biomass (such as plant straw, dead branches, animal feces and municipal sludge) under anaerobic or anoxic conditions. Biochar has rich pore structure and specific surface area, and has good adsorption performance due to a large number of functional groups. In addition, biochar has many advantages such as abundant raw materials, low price and recyclability. It is widely used in environmental pollution remediation, soil improvement and carbon fixation, especially in the adsorption of pollutants in wastewater. It has great application prospects.

[0003] However, there are certain defects when using biochar alone for water treatment. For example, when using biochar to treat environmental problems for a long time, pollutants may desorb from the surface of biochar, and the treatment effect on low-concentration pollutants is not ideal. Modification technology can improve the physical and chemical properties of biochar, increase the adsorption capacity of pollutants, and reduce the possibility of pollutant desorption. Common modification methods include acid-base modification, oxidant modification, biological modification, organic compound modification, plasma modification, ball milling modification, steam modification, and gas purge modification. However, most modification methods have the risk of secondary pollution, high cost, limited treatment effect, long cycle, and are affected by environmental conditions. These shortcomings lead to the current biochar modification equipment. The complex operation, high risk and low production efficiency have caused the technology of industrial production of modified biochar to encounter bottlenecks. Utility Model Content
