<p>PROBLEM TO BE SOLVED: To obtain a microbial carrier useful, e.g. for a low-cost high-efficiency waste water treatment by using a porous hollow tube, etc., made of a hydrophobic plastic as a substrate, introducing a water-soluble polymer containing microorganisms into the pore and insolubilizing the polymer. SOLUTION: The porous hollow tube or a pseudo-hollow tube having a C- shaped cross-section and made of a hydrophobic plastic selected from among polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate, epoxy resin and their derivatives is used as a substrate. A water- soluble polymer containing microorganisms and composed of hydrolyzed product of N-vinylcarboxylic acid amide (co)polymer, hydrolyzed product of polyvinyl acetate, chitosan, sodium alginate, sodium polyacrylate or their mixture is introduced into the pore and the water-soluble polymer is insolubilized to obtain the objective microbial carrier exhibiting the effect at the start of the addition of the carrier and having high bio-processing capability.</p> |
