STICKING ORGANISM MONITORING METHOD OF WATER INTAKE FACILITY AND STICKING ORGANISM MONITORING SYSTEM OF WATER INTAKE FACILITY
PROBLEM TO BE SOLVED: To reduce maintenance cost by optimizing cleaning time by preventing the occurrence of an obstacle by a sticking organism, by inexpensively monitoring an inhabitation state of the sticking organism on the inside of an operating water intake facility.SOLUTION: A constant quantity of seawater is collected from a water intake port 3, a water intake pit 4 and a water outlet 5 by a water collection process 10, and a quantity of feces is measured in accordance with a shape and a size by separating the feces on respective seawaters collected by a feces analysis process 20, and a plankton quantity is measured on the respective seawaters collected by a plankton quantity measurement process 30, and the water temperature of the seawater collected by a water temperature measurement process 40 is measured, and a difference in a quantity of feces in accordance with the shape and the size between water collection points of adjacent two places is determined by a sticking organism inhabitation state estimation process 50, and the inhabitation number of sticking organism between the water collection points is estimated in accordance with a kind and a size of the sticking organism by taking into consideration the water temperature and a depletion quantity of plankton. A dropout time is predicted by trend-analyzing the inhabitation number of sticking organism.SELECTED DRAWING: Figure 1
【課題】稼動中の取水設備の内部における付着生物の生息状況を低コストでモニタリング可能とし、付着生物による障害発生を未然防止するとともに清掃時期を最適化してメンテナンスコストを低減できるようにする。【解決手段】採水工程１０により取水口３、取水ピット４、放水口５から一定量の海水を採水し、糞解析工程２０により採水されたそれぞれの海水について糞を分離して形状別・大きさ別に糞の量を測定し、プランクトン量測定工程３０により採水されたそれぞれの海水についてプランクトン量を測定し、水温測定工程４０により採水された海水の水温を測定し、付着生物生息状況推定工程５０により隣接する２箇所の採水ポイント間の形状別・大きさ別の糞の量の差分を求め、水温とプランクトンの減耗量とを勘案して採水ポイント間の付着生物の生息数を付着生物の種類別・大きさ別に推定する。また、付着生物の生息数をトレンド解析して脱落時期を予測する。【選択図】図１
