DISSOLVED OXYGEN REMOVAL SYSTEM AND DISSOLVED OXYGEN REMOVAL METHOD FOR WELL WATER
PROBLEM TO BE SOLVED: To provide a dissolved oxygen removal system and a dissolved oxygen removal method for well water which can prevent blocking of a structure in the well or in an aquifer due to dissolved oxygen of the well water.SOLUTION: A dissolved oxygen removal system 1A comprises: a well 2 having well water W and being flooded or pumped; a deaeration pipe 3 that one end 31 is inserted in the well 2; and a vacuum pump 4 connected to another end 32 of the deaeration pipe 3 and raising the well water W from the one end 31 into the deaeration pipe 3 to an appointed height h. When the vacuum pump 4 is operated, the well water W is raised from the one end 31 of the deaeration pipe 3 into the deaeration pipe 3, and the surface of the water in the deaeration pipe 3 stops at a height h equivalent to a head pressure depending on degree of decompression. the dissolved oxygen of the well water W is deaerated from the well water W with decompression.SELECTED DRAWING: Figure 2
【課題】井戸水の溶存酸素に起因する井戸内構造物又は帯水層内部の目詰まりを一層防止することができる井戸水の溶存酸素除去システム、及び溶存酸素除去方法を提供する。【解決手段】溶存酸素除去システム１Ａは、井戸水Ｗを擁し注水又は揚水が行われる井戸２と、一端３１が井戸２内に挿入された脱気管３と、脱気管３の他端３２と連通し、一端３１から脱気管３内に井戸水Ｗを所定の高さｈまで引き上げる真空ポンプ４とを備える。真空ポンプ４を稼働させると、脱気管３の一端３１から脱気管３内に井戸水Ｗが引き上げられ、減圧の程度に応じた水頭圧相当の高さｈで脱気管３内の水面が停止する。そして、減圧に伴い井戸水Ｗの溶存酸素が井戸水Ｗから脱気される。【選択図】図２
