Preparation method of efficient biofilm forming material, and preparation method of biofilm forming filler

The invention discloses a preparation method of an efficient biofilm forming material, and a preparation method of a biofilm forming filler. The preparation method comprises the following steps: 1) removing surface edges and corners of a weakly magnetic porous material with a particle size of 30-50 mm for later use; (2) adding ferric oxide and potassium hydroxide into 3.5-4.5 cubic meters of wateraccording to a molar ratio of 1:3, uniformly mixing and stirring, and standing for 36-48 h at a temperature of 30-50 DEG C for later use, wherein the total weight of the ferric oxide and the potassium hydroxide is 95-105 Kg; and 3) pouring the weakly magnetic porous material in the step 1) into a water tank, adding the weakly magnetic porous material surface modifier prepared in the step 2) to immerse the weakly magnetic porous material, and after the modifier is circulated for 4 hours, taking out the weakly magnetic porous material, draining, drying in the air, and obtaining the biofilm forming material after modification is completed. According to the invention, the prepared material can change along with the environment, shortens the time for adapting to the environment, has certain mechanical strength, microorganism bearing capacity, specific weak magnetism and natural trace far infrared rays, and can stimulate the activity of microorganisms.
