METHOD FOR REDUCING ADHESION OF AQUATIC ORGANISM TO WATER INTAKE FACILITY
PROBLEM TO BE SOLVED: To provide a method for reducing adhesion of an aquatic organism to water intake facilities at low cost, the method that can be applied to the operating water intake facilities, may not generate environmental pollution, and eliminates the need for performing large remodeling to the existing water intake facilities.SOLUTION: A method for reducing adhesion of an aquatic organism to water intake facilities includes the steps of: disposing artificial substrate units facilitating adhesion of larvae of the aquatic organism and not making the flow stagnate in 3-stages along the flow in the upstream side running water of the water intake facilities, and recovering the artificial substrate unit of the most rear stage to the flow on the water before the adhering larvae of the aquatic organism grow greatly every one week; transferring the artificial substrate units left in the running water to the rear stage side to the flow; installing the artificial substrate unit waiting on the water to the front stage side of the transferred artificial substrate units; washing the recovered artificial substrate unit in water and drying it to remove the adhering larvae of the aquatic organism; and making the artificial substrate unit removed of the adhering larvae of the aquatic organism wait as the artificial substrate unit to be installed next. The above steps are executed and the artificial substrates are recovered in a cycle for 3-weeks and reused.SELECTED DRAWING: Figure 9
【課題】稼働中の取水設備に適用でき、環境汚染を発生させず、既存の取水設備に対して大きな改造を行うことなく低コストで取水設備への水生生物の付着を低減する。【解決手段】取水設備の上流側流水中に、水生生物の幼生が付着しやすく、流れを停滞させない人工基質ユニットを流れに沿って３段配備し、一週間ごとに、流れに対して最後段の人工基質ユニットを付着した水生生物の幼生が大きく成長する前に水上に回収する工程と、残された流水中の人工基質ユニットを流れに対して後段側に移設する工程と、水上で待機中の人工基質ユニットを移設させた人工基質ユニットの前段側に設置する工程と、回収された人工基質ユニットを水洗い・乾燥させて付着した水生生物の幼生を除去する工程と、付着した水生生物の幼生を除去した人工基質ユニットを次に設置する人工基質ユニットとして待機させる工程を実行し、人工基質を３週間周期で回収して・再利用する。【選択図】図９
