Pretreatment system for solid organic hazardous wastes

The invention relates to the field of hazardous waste treatment, and relates to a treatment system for solid hazardous wastes, in particular to a treatment system for solid organic hazardous wastes. The treatment system for the solid organic hazardous wastes sequentially comprises a first screening unit, a crushing unit and a second screening unit in the material movement direction. The crushing unit comprises a crusher used for crushing the solid organic hazardous wastes into particles with the particle size smaller than 150 mm, a crushing chamber is arranged in the crusher, the side wall ofthe crushing chamber communicates with a dredging pipe, and a safety blasting film is fixed to the end, away from the crushing chamber, of the dredging pipe. According to the scheme, impurities in thesolid organic hazardous wastes are removed and treated into products with uniform particle sizes, and the technical problems that when the solid organic hazardous wastes are incinerated in a cement kiln, the properties such a
