Abstract

The invention relates to a biomembrane carrier material, and specifically relates to a modified alveolar stone doped bioactive polylactic acid-polypropylene composite fiber carrier material and a preparation method thereof. The conventional pure inorganic and organic carriers are mixed to prepare the composite material; the fiber silk made of polymer materials such as polypropylene, polylactic acid, and the like has a better compatibility with microbes and good hydrophilicity. Moreover, the doped modified alveolar stone has a uniform and efficient adsorption performance. The added colloid graphite powder improves the mechanical performance of fiber silk and improves the adsorption performance of carrier on microbes. The fiber bundle is soaked in composite silica gel, after the treatment, the fiber bundle can adhere to a carbon source in fibers, and the growth of microbes is accelerated. The provided composite fiber carrier material has the advantages of light weight, large activated surface area, high bioactivity, and suitability for microbial growth and propagation and is capable of forming a film in a short time. The filling material made of the composite fiber carrier material has the advantages of good fluidity, difficulty in clustering, and aging resistant property, and is capable of improving the water purification efficiency.

Description

technical field [0001] The invention relates to a biofilm carrier material, in particular to a bioactive 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, regeneration, ...
