Embodiment 1
[0037] A fluidized bed biological filler, consisting of the following components (g),
[0038]
[0039]
[0040] Wherein the coupling agent is a silane coupling agent, the hydrophilic agent is stearic acid, the antioxidant is antioxidant 1010, and the nutritional agent is bagasse.
[0041] Its preparation method is
[0042] Sp1: Put polypropylene particles, attapulgite, hydrophilic agent, diatomaceous earth, magnetic material, antioxidant, nutrient, and dispersant into the stirring device and stir evenly;
[0043] Sp2: Blend the uniformly stirred materials, lubricants and coupling agents in a kneader at a kneading temperature of 140°C, and then obtain semi-finished fillers by injection molding in an injection molding machine at a temperature of 160°C;
[0044] Sp3: Magnetize the obtained semi-finished filler in a magnetizer to make the semi-finished filler obtain magnetism to obtain a finished biological filler.
