Abstract Provided are: a support for immobilizing microorganisms for water treatment, the support being hydrophilic and water swellable, and also having excellent chemical resistance and abrasion resistance; a resin-foamed body used for the support; and a starting material composition thereof. A support for immobilizing microorganisms for water treatment according to the present invention is formed of a resin-foamed body that contains a carbodiimide group, the resin-foamed body being made with a resin-foamed body starting material composition that includes a carbodiimide group-containing compound. The volume expansion ratio, which is expressed by the ratio of the water-swelled volume to the absolute dry state volume, is 110-1000%. L'invention concerne : un support pour immobiliser des microorganismes pour le traitement des eaux, le support étant hydrophile et gonflable dans l'eau, et présentant également une excellente résistance chimique et une excellente résistance à l'abrasion ; un corps en mousse de résine utilisé pour le support ; et une composition de matière de départ de celui-ci. Un support pour immobiliser des microorganismes pour le traitement des eaux selon la présente invention est formé d'un corps en mousse de résine qui contient un groupe cyanamide, le corps en mousse de résine étant fabriqué avec une composition de matière de départ de corps en mousse de résine qui comprend un composé contenant un groupe cyanamide. Le taux d'expansion du volume, qui est exprimé par le rapport entre le volume gonflé d'eau et le volume absolu à l'état sec, est de 110 à 1000 %. 親水性及び水膨潤性のみならず、優れた耐薬品性及び耐摩耗性をも兼ね備えた水処理用微生物固定化担体、並びにこれに用いられる樹脂発泡体及びその原料組成物を提供する。本発明の水処理用微生物固定化担体は、カルボジイミド基含有化合物を含む樹脂発泡体原料組成物を用いて製造されたカルボジイミド基を含有する樹脂発泡体で形成され、絶乾状態の体積に対する水膨潤時の体積の比で表される体積膨潤率が110~1000%である。
