BIOCATALYST-CARRYING MATERIAL FOR BIOREACTOR, BIOCATALYST-IMMOBILIZED CARRYING MATERIAL, AND METHOD FOR TREATING WITH BIOCATALYST |
摘要 |
<p>PURPOSE:To provide the subject carrying material containing a water-absorbing material, having a micro-filter effect, immobilizing a biocatalyst in a short time and improved in catalytic efficiency, long period preservability and handling property. CONSTITUTION:A biocatalyst-carrying material (A) for bioreactor is composed of starch-acrylic acid salt graft copolymer in the form of fiber with uneven surface having micro-filter effect which comprises a double-layer structure of a non-water-absorbing material and a water absorbing material having a swell of >=2 and a water-absorbing rate of several seconds to several minutes until saturation. The component A is immersed in a tank containing a bio- catalyst (B) such as anaerobic bacteria to immobilize the component B on the surface of the component A. The fixed component B is comprehensively immobilized with an immobilizing material such as cellulose to produce a biocatalyst-carrier (C) for a bioreactor. The component C is immersed in a solution in a treating tank to which the water to be treated is fed and operated to biologically decompose an organic substance by biocatalyst method.</p> |
