The invention discloses a preparation method of a nano-activated carbon particle-doped PLA bio-based degradable fiber filter material for industrial flue gas, comprising intermediate treatment steps such as preparation of resin masterbatch doped with nano-activated carbon particles, mixing of the doped masterbatch with PLA resin masterbatch, extrusion and spinning; and preparing nano-activated carbon particle-doped PLA bio-based degradable staple fibers through bundling, coiling, chopping and other operations. The technical solution of the invention yields a filter material with biodegradability, adsorption performance and applicability for filtration of particulate matter in low-temperature industrial flue gas. The disclosed filter material is environmentally friendly, easily degradable and features high filtration efficiency.
