The invention discloses a solid garbage compression treatment vehicle. The solid garbage compression treatment vehicle structurally comprises a garbage vehicle, a garbage loading box, a feeding hopper, a rear hopper control plate and a hydraulic oil tank, wherein the garbage loading box consists of a box body, a rolling mechanism, a bearing plate, a feeding conveying device, a filler, a pressing mechanism and a sewage recovery mechanism, garbage in the filler is slowly conveyed to the bearing plate of the garbage loading box through the feeding conveying device, solid garbage is ground througha first rolling roller and rolled into a second rolling roller, solid garbage is subjected to secondary compression, so that the working efficiency is improved, the garbage and the liquid are filtered out by using the sewage recovery mechanism, the situation that the garbage and the sewage are mixed to generate some unpleasant gases is avoided, the situation that the sewage flows out of the garbage loading box to influence the cleanliness of a road is avoided, the garbage is squeezed and stored through a pressing mechanism, gaps between the garbage are reduced, and therefore the storage spaceof the garbage loading box is increased.
