The invention relates to a treatment device, in particular to a municipal refuse recovery treatment device. The municipal refuse recovery treatment device comprises a whole machine support frame, a movement support frame, a power mechanism, a transmission mechanism, a pulverizing mechanism, control mechanisms, connecting rods, a sieving mechanism, a non-iron rigid storage box, an iron storage boxand a flexible storage box, wherein the movement support frame and the whole machine support frame form displacement rails; the pulverizing mechanism is glidingly connected into the displacement railformed by the movement support frame and the whole support frame; the movement support frame and the pulverizing mechanism are in engaged transmission through a gear; the two control mechanisms are respectively and fixedly connected with the front side and the back side of the whole machine support frame; the upper ends of the two connecting rods are respectively and fixedly connected onto the twocontrol mechanisms; the lower ends of the two connecting rods are respectively and fixedly connected with the front side and the back side of the sieving mechanism, so that rigid articles and flexible articles in refuses are sieved; the rigid articles in the refuse are subjected to crushing treatment; the crushed rigid refuses are subjected to iron and non-iron sieving.
