The invention belongs to the technical field of solid waste treatment, and specifically relates to a solid waste treatment system with a pretreatment process, which includes a treatment box, a primary crushing assembly and a crushing roller. A sealing plate, a primary crushing assembly is arranged above the rotating sealing plate, and an electro-hydraulic telescopic rod is connected between the lower end of the rotating sealing plate and the processing box; the present invention realizes the crushing of the elastic arc by setting the crushing knife as a combined type. The fixed waste between the curved surface on the plate and the two sides of the triangular slider is crushed, thereby increasing the crushing effect on solid waste; by setting the triangular slider to slide and install in the chute on the sealing plate, On the one hand, it prevents the problem of excessive wear caused by excessive impact force after the single elastic arc plate is stressed; on the other hand, it realizes that the solid waste is evenly spread on the two crushing rollers, thereby reducing the possibility of the crushing motor being burned out. Thereby improving the service life of the crushing motor.
