WATER TREATMENT EQUIPMENT AND WATER TREATMENT METHOD

To provide water treatment equipment and a water treatment method which enable adjustment of chloride concentration.SOLUTION: Water treatment equipment comprises: a first filtration device which removes iron or manganese by causing water to flow through the same; a chemical solution injection device which injects chlorine to raw water supplied to the first filtration device, on a primary side of the first filtration device; a second filtration device which removes chlorine in first filtered water on a secondary side of the first filtration device; a first treatment water conduit through which first treatment water having undergone first filtration treatment flows from the first filtration device to the second filtration device; a second treatment water conduit through which second treatment water having undergone filtration treatment at a secondary side of the second filtration device flows; and a bypass flow passage which supplies first treatment water to the second treatment water conduit from the first treatment water conduit.SELECTED DRAWING: Figure 1 【課題】塩素濃度を調整することが可能な水処理装置及び水処理方法を提供する。【解決手段】本発明の一形態にかかる水処理装置は、通水することで水に含まれる鉄またはマンガンを除去する第１濾過装置と、前記第１濾過装置の一次側において、第１濾過装置に供給される原水に塩素を注入する薬液注入装置と、前記第１濾過装置の二次側において、濾過処理後の第１処理水の塩素を除去する第２濾過装置と、前記第１濾過装置から前記第２濾過装置に第１濾過処理された第１処理水が流れる第１処理水路と、前記第２濾過装置の二次側において濾過処理された第２処理水が流れる第２処理水路と、前記第１処理水路から第１処理水を前記第２処理水路に供給するバイパス流路と、を有する通水路と、を備える。【選択図】図１
