[0052] A kind of preparation method of high-efficiency bio-film-hanging material provided by the invention comprises the following steps:
[0053] Step 1: Shape processing of weakly magnetic porous materials
[0054] Remove the surface edges and corners of the weakly magnetic porous material with a particle size of 30-50mm, high rare earth content, and a surface magnetic field strength of 0.11-60mT, and then use a fan to blow off the dust on the surface before use;
[0055] The composition list of the weakly magnetic porous material is as follows:
[0056]
[0057] Step 2: Preparation of Surface Modifier for Weakly Magnetic Porous Materials
[0058] Fe2O3, Fe 3 + and potassium hydroxide, in OH - According to the molar ratio of 1:3, add it to 3.5-4.5 cubic meters of water, mix and stir evenly, and let it stand for 36h-48h under the condition of 30-50 degrees, and set aside; among them, the total amount of ferric oxide and potassium hydroxide The weight is 95~105Kg;
