The utility model provides a multiphase flow attitude membrane carrier of microorganism packs, belongs to environmental protection and water processing technique field. This carrier packs, and to adopt high density polyethylene be major ingredient, calcium carbonate and starch be the auxiliary material, the carrier adoption light-wall pipe column structure of packing, be equipped with in the light-wall pipe column structure the mutual strengthening rib that becomes an angle of 90 degrees and a plurality of in the gusset, be equipped with the helicla flute on the outer wall. This carrier packs and has solved conventional biofilm carrier under effects such as water conservancy, stirring, aeration, and the problem of the fluidization of rolling that can not be positive has remedied defects such as the surperficial smooth adhesive force of conventional filler is poor, hydrophobic, specific surface is little. Have the filler structure of even aperture on the outer wall, it is the suspended state in aqueous to pack, under the effect of external force, can roll abundant and water contact reaction in the pond from top to bottom. The carrier packs shaggyly, is fit for the membrane of hanging of microorganism. The filler has very strong pliability, is fit for " fluidization " reaction of high strength. Pack and make for hydrophilic material, shorten greatly and hang the membrane time.
