PROBLEM TO BE SOLVED: To provide a method and an apparatus for preparing a novel biomagnetic suspension filler for water treatment. SOLUTION: A magnetic powder is alkali-modified and activated, and then polyurethane is copolymerized with a silicone emulsion to be modified, and a dispersion lubricant, a cross-linking agent and a pologene are added and kneaded at high speed to obtain a mixture. The mixture is extruded directly, molded and cut, vacuum dried to remove pologene, the inside of the molding filler is made porous, a suspension filler is obtained, the suspension is magnetized and then the surface reinforcing component is added. Load to obtain biomagnetic suspension filler. [Selection diagram] None |
