Abstract: A treated water tank in oil sand plant, comprising a first housing; an inlet provided in the first housing, through which a treated water flows in; an outlet provided in the first housing, through which the treated water stored is discharged; a second housing installed in the upper side of the first housing and communicated with the first housing by a pressure-controlling pipe; a gas discharge pipe provided in one side of the second housing for opening to the air; and a gas curtain provided in the second housing for preventing the treated water stored in the first housing from being in contact with the air. The treated water tank in oil sand plant according to the present invention simplifies the process of producing the treated water to be reused from the production water, reduces the risk of environment contamination due to the reuse of more purified treated water.
