RECHARGE SYSTEM AND RECHARGE METHOD
To provide a recharge system and a recharge method that are capable of eliminating sewage water discharge of effluent such as underground water at the time of maintenance, and makes it possible to implement efficient and inexpensive preferable operation.SOLUTION: A recharge system comprises: oxidant addition means 1 for adding an oxidant P to object water W1 at ground level; a raw water tank 2 for temporarily retaining the object water W1 including the oxidant P added by the oxidant addition means 1; removal processing means 3 for filtering the object water W1 sent from the raw water tank 2, using a filtering device 11; and a water pouring well 4 for pouring object water W2 after processing of the removal processing means 3 into the underground. The capacity of the raw water tank 3 is set depending on a washing frequency and/or washing time for performing backwashing on the filtering device 11.SELECTED DRAWING: Figure 1
【課題】メンテナンス時に地下水などの排出水を下水放流することを不要にでき、効率的且つ経済的で好適な運転を実現することを可能にするリチャージシステム及びリチャージ工法を提供する。【解決手段】地上で対象水Ｗ１に酸化剤Ｐを添加する酸化剤添加手段１と、酸化剤添加手段１で酸化剤Ｐを添加した対象水Ｗ１を一時的に貯留する原水タンク２と、原水タンク２から送られた対象水Ｗ１をろ過装置１１でろ過する除去処理手段３と、除去処理手段３で処理した後の対象水Ｗ２を地中に注水するための注水井戸４とを備える。原水タンク３は、ろ過装置１１を逆洗する洗浄頻度及び／又は洗浄時間に応じて容量を設定する。【選択図】図１
