PROBLEM TO BE SOLVED: To provide a technique capable of easily removing contaminants contained in water flowing in a waterway.SOLUTION: A device for removing contaminants includes a box-type body, an inflow part which is installed upstream of the body and at a lower position than a waterway and through which contaminants-containing water supplied from the waterway is introduced, an outflow part which is installed downstream of the body and through which the contaminants-removed water is discharged, an underwater dam plate installed between the inflow part and the outflow part, and a capture part which is installed in the body and upstream of the underwater dam plate and serves to capture contaminants contained in the water introduced through the inflow part.COPYRIGHT: (C)2014,JPO&INPIT【課題】水路を流れる水に含まれる汚染物質を簡易に除去できる技術を提供する。【解決手段】箱状の本体部と、前記本体部の上流側、かつ水路よりも低い位置に設けられ、当該水路から供給される汚染物質を含む水が流入する流入部と、前記本体部の下流側に設けられ、前記汚染物質が除去された水を排出する排出部と、前記流入部と前記排出部との間に設けられる潜り堰板部と、前記本体部内、かつ前記潜り堰板部よりも上流側に設置され、前記流入部から流入する水に含まれる汚染物質を捕捉する捕捉部と、を備える。【選択図】図2
