NOVELTY - An urban solid waste is processed by pre-selecting wastes; taking selected large bricks as brick-making materials; crushing large-long organic materials, mixing them with the pre-selected wastes, screening, taking screened underflows as compost or brick-making materials, drying the screened residue, and sending them into waste air separation device to air separate heavy materials, humic organic materials, un-recyclable combustible materials, and slight plastics; recovering metals through the heavy materials and crushing the heavy materials to be used as brick-making materials.    USE - Method for processing urban solid waste (claimed).    ADVANTAGE - The method has less investment, uses simple device which occupies less space, has low running cost, has no secondary pollution, and provides complete reduction.    DETAILED DESCRIPTION - Processing urban solid waste comprises:    (A) pre-selecting wastes through waste screen to obtain pre-selected wastes by selecting out large brick and large-long organic materials whose particle size is more than 300 mm;    (B) taking the selected large bricks as the brick-making materials after being crushed;    (C) crushing the large-long organic materials to materials with particle size less than 100 mm, further mixing the large-long organic materials with the pre-selected wastes after magnetic separating process and sending them into 20-25 mm drum screen for screening, taking the screened underflows as compost or the brick-making materials after high temperature disinfection, drying the screened residue, and sending them into waste air separation device to air separate the heavy materials, humic organic materials, un-recyclable combustible materials and slight plastics according to their specific gravity;    (D) recovering metals through the heavy materials, picking up battery, high temperature disinfecting, and crushing the heavy materials to be used as brick-making materials;    (E) taking the humic organic materials as compost or directly sending them into incinerator;    (F) crushing un-recyclable combustible materials to prepare waste derived fuel; and    (G) regenerating particles with the slight plastics.    An INDEPENDENT CLAIM is included for a device for processing urban solid waste.
