NOVELTY - High-adsorbing biological membrane carrier material comprises 8-10 pts. wt. diatomite, 14-18 pts. wt. polylactic acid, 0.3-0.4 pts. wt. oxidized graphene, 4-6 pts. wt. cassava starch, 2-3 pts. wt. arabic gum, 40-50 pts. wt. polypropylene, 8-12 pts. wt. chitosan, 2-3 pts. wt. polyvinyl alcohol, 2-4 pts. wt. nano-carbon sol, 3-5 pts. wt. lignocellulose, 1-2 pts. wt. bentonite, 1-2 pts. wt. trimethylhexadecylammonium bromide, 0.5-1.5 pts. wt. silica sol, 0.3-0.5 pts. wt. humic acid sodium, and 15-20 pts. wt. water. USE - High-adsorbing biological membrane carrier material. ADVANTAGE - The high-adsorbing biological membrane carrier material has light weight, large area of activation, carbon-rich source, small influence adsorption performance to the change of the environmental temperature, good fluidity, good absorption property, corrosion resistance, durable efficiency, and improves the water purifying effect, and is not easy to agglomerate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high-adsorbing biological membrane carrier material, which involves: (A) mixing the raw materials uniformly mixed, then feeding into a twin-screw extruder for compounding to obtain composite pellets; (B) extruding composite pellets at a temperature of 150-200 degrees C, then cooling the pellets are cooled and putting into a melt-blowing and subjecting to spun spinning to obtain filaments; and (C) curing obtained filaments and converting into composite fiber bundles having diameter of 1-2 mm to obtain desired product.
