PROBLEM TO BE SOLVED: To provide a pollution prevention device that suppresses turbidity of water stored in a reservoir and others, while allowing surface layer water to circulate selectively.SOLUTION: A pollution prevention device includes a float part 20 floating on water, a pollution prevention film 10 hung from the float part 20 through a tension belt 40, and a weight 30 fitted at a bottom edge part of the pollution prevention film 10. The pollution prevention film 10 includes a surface layer opening 12 that allows surface water to circulate through the float part 20, and an impermeable curtain part 11 below the surface layer opening 12. By installing such a pollution prevention device 1 on an upstream side almost in parallel to and leaving an interval from a dam body of a reservoir and others, turbidity of stored water on a downstream side may be suppressed and the surface layer water may circulate toward the downstream side.SELECTED DRAWING: Figure 1A
【課題】本発明は、ため池等貯水池に貯えられている水の濁りを抑えるとともに、表層水を選択的に流通可能とする汚濁防止装置を提供する。【解決手段】水上に浮遊するフロート部２０と、そのフロート部２０に、テンションベルト４０を介して吊り下げられた汚濁防止膜１０と、その汚濁防止膜１０の下端部に取り付けられた重錘３０と、を備え、その汚濁防止膜１０又はフロート部２０に表層水が流通可能な表層開口部１２を備え、その表層開口部１２の下に不透水性のカーテン部１１を含む。このような汚濁防止装置１を、ため池等貯水池のダム堤体から上流側に距離を設けて略平行に設置することにより、下流側の貯水の濁りを抑えるとともに、表層水が下流側に流通可能となる。【選択図】図１Ａ
