Abstract

See full text

Provided are a treatment apparatus and a treatment method treating a waste cleaning liquid discharged from a process of producing an electrode of a lithium-ion secondary battery, in which a liquid component and a solid component are efficiently separated from each other, and the liquid component can be sufficiently collected and subjected to volume reduction treatment. The treatment apparatus includes: a stirring tank stirring the waste cleaning liquid; a liquid feed line that takes out the waste cleaning liquid from the stirring tank; and a thin film evaporator evaporating a cleaning liquid in the waste cleaning liquid to separate the solid component. Then, in the treatment method, the waste cleaning liquid is stirred in the stirring tank, the waste cleaning liquid is supplied to the thin film evaporator in a state in which the solid component is diffused, and the cleaning liquid in the waste cleaning liquid is evaporated.
