| Zusammenfassung: | To provide a microorganism-immobilized carrier characterized by excellent fluidity and reduced floating of the carrier during water treatment.SOLUTION: In order to solve the problem, there is provided a microorganism-immobilized carrier containing a hydrophilic polyurethane resin and a resin having a different hydrophilicity from the hydrophilic polyurethane resin. The surface of the carrier swollen by water has an uneven structure, and a specific gravity is 1.01 to 1.05.SELECTED DRAWING: None
【課題】流動性に優れ、なおかつ水処理中の担体の浮揚が低減されることを特徴とする、微生物固定化担体の提供。【解決手段】親水性ポリウレタン樹脂と、前記親水性ポリウレタン樹脂とは親水性が異なる樹脂とを含む微生物固定化担体であって、水により膨潤した前記担体の表面が凹凸構造を有し、かつ、比重が１．０１〜１．０５であることを特徴とする微生物固定化担体により解決する。【選択図】なし |
