Problems solved by technology

[0004] In recent years, the production technology of activated carbon fiber has developed rapidly, and it also has related applications in water pollution control, biochemical reaction, food fermentation, etc. as a carrier of microorganisms. The surface energy of the bioactive carbon fiber prepared by this method is still not high, and further improvement is needed; at the same time, the bioactive carbon fiber prepared by this method has low strength and poor impact resistance, and is not suitable for the treatment of a large amount of sewage
[0005] Based on some deficiencies of the current bioactive carbon fiber, there is no report on its application as a biofilm carrier in water treatment

Description

technical field [0001] The invention relates to a preparation method of bioactive carbon fiber. Background technique [0002] Bioactive carbon fiber is a new type of adsorption material prepared by combining carbon fiber and activated carbon technology. It has ultra-high specific surface area, micro-mesoporous multi-level structure, small pore size distribution, large adsorption capacity, fast adsorption and desorption speed, and easy regeneration. Features. At present, the raw materials of activated carbon fiber precursors are generally pitch, viscose fiber, polyacrylonitrile and phenolic resin, among which phenolic activated carbon fiber has higher carbonization yield, specific surface area and electrical conductivity than other activated carbon fibers received widespread attention. Bioactive carbon fiber is mainly used for environmental purification, and is mostly used as an excellent adsorbent for air purification, which can absorb hydrogen sulfide in gas and remove un...
