Abstract

The purpose of the invention is to provide a separation and recovery device capable of separating and recovering a liquid having a high solvent concentration from a development waste liquid containing a development residue, with a high processing capacity without mixing the development residue in the recovered liquid. The device is a separation and recovery device for separating and recovering a solvent component from a development waste liquid containing a development residue and has a waste-liquid heating mechanism for heating the development waste liquid, an atomization chamber having an ultrasonic element for atomizing the development waste liquid heated by the waste-liquid heating mechanism into mists, and a mist recovery mechanism for recovering the mists formed in the atomization chamber.
