<p><P>PROBLEM TO BE SOLVED: To provide a microorganism immobilizing carrier which allows nitrification activity to arise early, and further has excellent carrier strength, and to provide a method for treating organic waste water while the carrier is charged to a nitrification tank. <P>SOLUTION: The microorganism immobilizing carrier for water treatment is composed of a gel-like substance obtained by polymerizing polymerizable unsaturated monomers containing a (meta)acrylamide derivative, wherein the using ratio between a water-swellable clay mineral and the polymerizable unsaturated monomers is 10/1 to 1/30, in the presence of the water-swellable clay mineral and water, wherein compression (fracture) strength is 0.01 to 15 MPa, and a rate of compression deformation upon fracture is 40 to 98%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
