WATER QUALITY MANAGEMENT SYSTEM AND WATER QUALITY MANAGEMENT METHOD
To provide a water quality management system capable of suppressing metal concentration in water discharged from a dam reservoir.SOLUTION: A water quality management system 1 controls metal concentration in the reservoir water by activating metal-oxidizing bacteria in the reservoir water of a dam reservoir R equipped with an embankment B having at least one outlet G1, G2, G3 on a downstream side of the dam reservoir R. The water quality management system 1 includes an oxygen concentration sensor 2 for measuring the dissolved oxygen concentration of the reservoir water in a deep layer downstream of the dam reservoir R, an oxygen supply unit 3 for supplying oxygen to the reservoir water in a deep layer upstream of the dam reservoir R, and a control unit 4 for adjusting an amount of oxygen supplied by the oxygen supply unit 3 according to the dissolved oxygen concentration measured by the oxygen concentration sensor 2.SELECTED DRAWING: Figure 1
【課題】ダム貯水池から放出される水の金属濃度を抑制することができる水質管理システムを提供すること。【解決手段】本発明に係る水質管理システム１は、下流側に少なくとも１つの出水口Ｇ１，Ｇ２，Ｇ３を有する堤体Ｂを備えるダム貯水池Ｒの貯留水中の金属酸化細菌を活性化させることにより、前記貯留水中の金属濃度を抑制する水質管理システム１であって、前記ダム貯水池Ｒ内の下流側の深層の前記貯留水の溶存酸素濃度を測定する酸素濃度センサ２と、前記ダム貯水池Ｒ内の上流側の深層の前記貯留水に酸素を供給する酸素供給装置３と、前記酸素濃度センサ２により測定された溶存酸素濃度に応じて前記酸素供給装置３による酸素供給量を調節する制御装置４と、を備える。【選択図】図１
