To provide an anti-fouling device which can supply a proper amount of ozone when preventing aquatic life from depositing by using the ozone.SOLUTION: An anti-fouling device relating to the present disclosure is an anti-fouling device for preventing aquatic life from depositing in a water passage where flowing water passes and is assembled with an ozone water generation part for generating ozone water by injecting ozone-containing fine air bubbles to water, a blending part for blending the ozone water with the flowing water, a concentration measurement part for measuring an oxidant concentration of the flowing water, and a control part which controls ozone concentration of the flowing water based on the oxidant concentration measured by the concentration measurement part, wherein the concentration measurement part is positioned on the downstream side than the blending part to the flowing water.SELECTED DRAWING: Figure 1 【課題】本発明は、オゾンにより水生生物の付着を防止する際に、適量のオゾンを供給できる防汚装置の提供を課題とする。【解決手段】本発明の一態様に係る防汚装置は、流水が通過する通水路に水生生物が付着することを防止する防汚装置であって、オゾンを含む微細気泡を水に注入したオゾン水を生成するオゾン水生成部と、上記オゾン水を上記流水に混合する混合部と、上記流水のオキシダント濃度を測定する濃度測定部と、上記濃度測定部で測定されるオキシダント濃度に基づいて上記流水のオゾン濃度を制御する制御部とを備え、上記流水に対して、上記濃度測定部が、上記混合部より下流側に位置する。【選択図】図１
