Building solid waste treatment equipment

The invention relates to the technical field of solid waste treatment, and particularly discloses building solid waste treatment equipment which is characterized in that an extrusion part is slidably mounted in an extrusion frame, an extrusion groove is located below the extrusion frame, an even number of molds are mounted in the extrusion groove, and each mold comprises a first plate and a second plate which are perpendicular to each other; the second plates are rotationally connected with the shaft rod through first elastic pieces, the rotating directions of every two adjacent first plates are opposite, clamping pieces are arranged on the first plates in the length extending direction of the first plates, the gravity centers of the clamping pieces are close to the lower portions, the clamping pieces are rotationally connected with the first plates, and the clamping pieces can be kept in a vertical state when the first plates rotate. A supporting frame is slidably installed below the extrusion groove in the
