UNDERGROUND WATER RECHARGE SYSTEM
To provide an underground water recharge system which holds water permeation performance of the recharge system and can prevent clogging of the ground in the vicinity of a water injection well.SOLUTION: An underground water recharge system includes: a pumping well 1 for pumping underground water W; an oxidizer addition part 12 which adds an oxidizer Ox to the underground water W pumped from the pumping well 1; a removal part 20 which introduces the underground water W to which the oxidizer Ox is added and treats the underground water W; a reducer addition part 14 which adds a reducer Re to the underground water W treated in the removal part 20 so that a residual quantity of the oxidizer Ox in the underground water W is a predetermined value or less; and a water injection well 2 for injecting the underground water W to which the reducer Re is added into the ground.SELECTED DRAWING: Figure 1
【課題】リチャージシステムの通水性能を保持し、注水井戸付近の地盤の目詰まりを防止することができる地下水リチャージシステムを提供する。【解決手段】地下水Ｗを揚水するための揚水井戸１と、揚水井戸１から揚水された地下水Ｗに酸化剤Ｏｘを添加する酸化剤添加部１２と、酸化剤Ｏｘが添加された地下水Ｗを導入し、地下水Ｗを処理する除去部２０と、除去部２０で処理された地下水Ｗに地下水Ｗ中の酸化剤Ｏｘの残量が所定値以下になるまで還元剤Ｒｅを添加する還元剤添加部１４と、還元剤Ｒｅが添加された地下水Ｗを前記地盤内へ注水するための注水井戸２と、を備える。【選択図】図１
