WATER QUALITY CONTROL METHOD AND WATER QUALITY CONTROL SYSTEM
To provide a water quality control method for supporting water quality control of effluent water by always monitoring contamination concentration of the effluent water generating from an earth structure surrounding constructed by using contaminated soil.SOLUTION: A water quality control method controls water quality of effluent water flowing out of a drain layer provided between an earth structure formed by using contaminated soil and natural ground. The method comprises steps of: continuously acquiring measurements related to a moisture state of the earth structure, by an underground sensor buried in the earth structure; continuously calculating an evaluation index for evaluating contamination concentration of the effluent water on the basis of the acquired measurements; always monitoring the effluent water by comparing the continuously calculated evaluation index with a determination threshold set in advance; and determining the possibility of the contamination concentration of the effluent water exceeding a control reference value, when the evaluation index exceeds the determination threshold.SELECTED DRAWING: Figure 4
【課題】汚染土壌を利用して構築した土構造物周辺から生じる流出水について、汚染濃度を合理的な評価指標で常時監視し、流出水の水質管理を支援する。【解決手段】汚染土壌を利用して構築した土構造物と地山との間に設けた排水層から流出する流出水の、水質を管理する水質管理方法であって、前記土構造物に埋設した土中センサにより、前記土構造物の水分状態に係る計測値を連続的に取得する工程と、取得した該計測値に基づいて、前記流出水の汚染濃度を評価する評価指標を連続的に算定する工程と、連続的に算定される前記評価指標と、あらかじめ設定した判定閾値とを比較することで、流出水を常時監視する工程と、前記評価指標が前記判定閾値を上回った場合に、前記流出水の汚染濃度が管理基準値を超過する可能性ありと判定する工程と、を備える。【選択図】図４
