PROBLEM TO BE SOLVED: To provide a ballast water processing method capable of discharging a small quantity of sterilized ballast water residing in the bottom of a ballast tank, reliably in a neutralized state.SOLUTION: At first, the ballast water after sterilization in a ballast tank 1 is discharged, while a neutralizing agent is being added to a drain water line 2 from a drain pump 3 to neutralize an active substance. Next, the neutralizing agent is added to the ballast tank 1, in which the ballast water is not discharged by the drain pump 3 but is left to neutralize the active substance in the ballast water left in the ballast tank 1, and is discharged by using an ejector 11.

    【課題】 バラストタンクの底部に残存する少量の殺滅処理済みのバラスト水を中和した状態で確実に放流することの可能なバラスト水の処理方法を提供する。【解決手段】 まず、バラストタンク1内の殺滅処理後のバラスト水を排水ポンプ3からの排水ライン2に中和剤を添加して活性物質を中和しながら排出する。次に排水ポンプ3で排出しきれずにバラスト水が残存しているバラストタンク1に中和剤を添加して、バラストタンク1に残存するバラスト水中の活性物質を中和し、エジェクタ11を使用して排出する。【選択図】 図1
