Abstract

The present invention relates to a biological film carrier material, particularly to a modified pumice-doped high-activity polylactic acid-polypropylene biological film composite fiber carrier material and a preparation method thereof. According to the present invention, the traditional simple inorganic carrier medium and the traditional simple organic carrier medium are subjected to mixed use so as to broaden the use range of the material, the fibers prepared from polypropylene, polylactic acid and other polymer materials have characteristics of good compatibility with microorganisms, hydrophilicity and environmental protection, the doped modified pumice has uniform and efficient adsorption capacity, the superfine zirconia is added to enhance wear resistance and corrosion resistance of the fiber bundle, and the carbon source is increased after the fiber bundle is subjected to a soaking treatment in a composite silica sol so as to accelerate the growth of microorganisms; and the prepared composite fiber carrier material has characteristics of light weight and large surface activation area, and the filler prepared from the prepared composite fiber carrier material has advantages of good fluidity, agglomerating resistance, durability, rapid film formation, stable performance and the like so as to further improve the water purification effect.

Description

technical field [0001] The invention relates to a biofilm carrier material, in particular to a highly active polylactic acid-polypropylene biofilm composite fiber carrier material doped with modified honeycomb stone and a preparation method thereof. Background technique [0002] Biofilm wastewater treatment technology is a technology that fixes microorganisms on the carrier to form a biofilm to degrade the pollutants in the wastewater. Therefore, the performance of the biofilm carrier will directly affect the efficiency of sewage treatment. To obtain efficient water treatment effects, It is particularly important to select suitable and efficient carrier materials. At present, the most widely used carrier materials are mainly soft polymer materials such as polyethylene, polystyrene, polyamide, and polypropylene, and inorganic fillers such as activated carbon, slag, and limestone. However, these Materials have some defects in biocompatibility, stability, durability, regenerati...
