▎ 摘　　要

NOVELTY - A polylactic acid composite biofilm carrier material comprises 10-14 pts. wt. diatomaceous earth, 14-18 pts. wt. polylactic acid, 0.3-0.4 pt. wt. graphene oxide, 4-6 pts. wt. tapioca starch, 2-3 pts. wt. gum arabic, 40-50 pts. wt. polyethylene, 8-12 pts. wt. chitosan, 4-7 pts. wt. talc powder, 2-4 pts. wt. nanocarbon sol, 3-5 pts. wt. lignocellulose, 2-4 pts. wt. mica, 1-2 pts. wt. trimethylhexadecylammonium bromide, 0.5-1.5 pts. wt. silica sol, 0.3-0.5 pt. wt. sodium humate and 15-20 pts. wt. water. USE - The polylactic acid composite biofilm carrier material is useful for purifying water. ADVANTAGE - The polylactic acid composite biofilm carrier material: has excellent flexibility, fluidity, durability, absorption property, corrosion resistance and wear resistance; is lightweight, environmentally-friendly, rich in carbon source and not easy to agglomerate; and can enhance the water purification effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the polylactic acid composite biofilm carrier material.
