가수분해성 폴리머를 함유하는 수지와 비가수분해성 폴리머를 함유하는 수지를 포함하는 수지 혼합체로부터, 가수분해성 폴리머A의 가수분해 성분a와 비가수분해성 폴리머B를 연속적으로 분리 회수하는 장치로서, 수지 혼합체를 파쇄하는 파쇄 유닛과, 파쇄 유닛에서 얻어진 파쇄물을 용융시켜서 유체로 하고, 고압에서 토출하는 용융 토출 유닛과, 용융 토출 유닛으로부터 토출된 유체를 연속적으로 수열 반응 처리하는 수열 반응 처리 유닛을 구비하고, 수열 반응 처리 유닛에 있어서, 가수분해성 폴리머A를 가수분해해서 그 가수분해 성분a를 소결 합금제의 격막에 침투한 물에 용해, 이행시키는 것에 의해, 비가수분해성 폴리머B를 분리시키는, 분리 회수 장치를 제공한다. Provided is a separation and recovery apparatus for continuously separating and recovering, from a resin mixture containing a resin containing a hydrolyzable polymer and a resin containing a nonhydrolyzable polymer, a hydrolytic component a of the hydrolyzable polymer A and the nonhydrolyzable polymer B, the apparatus including: a crushing unit that crushes the resin mixture; a melting/discharging unit that melts a crushed product obtained by the crushing unit to form a fluid and discharges the fluid at a high pressure; and a hydrothermal reaction treatment unit that continuously subjects the fluid discharged from the melting/discharging unit to a hydrothermal reaction treatment, wherein, in the melting/discharging unit, the hydrolyzable polymer A is hydrolyzed, and the hydrolytic component a thereof is dissolved and transferred into water permeating a sintered alloy diaphragm, thereby separating the nonhydrolyzable polymer B.
