Abstract: The present invention belongs to the field of sewage treatment, and relates to a method for preparing a modified natural wood material and an application thereof in sewage treatment. The method for preparing the modified natural wood material includes the following steps: S1. placing wood into a lignin removal solution, after a heating reaction, washing, impregnating, and lyophilizing the wood to obtain removed lignin wood; S2. blending TiO2 with NaBH4, performing low-heat reduction treatment, and then washing and drying to obtain reduced black titanium; S3. dispersing the reduced black titanium ultrasonically in a solvent, then coating dropwise on the removed lignin wood, and drying to obtain a modified natural wood material. The modified natural wood material prepared by the present invention has high disinfection and sterilization performance, and has the ability to remove bio-risk components.
