The present invention discloses a harmless and resource recovery system and method for a mercury containing lamp tube in a back light source of a liquid crystal display product; The present invention selectively crushes the LCD backlight lamp tube through a targeted multi-stage crushing multi-stage sorting combination process, and then separates valuable components in steps. Multi stage crushing includes: horizontal knife crushing, roller crushing, and shear crushing. The multi-level sorting sequence includes: multi-level vibration screening, magnetic separation, and drum cleaning. The present invention can achieve complete separation and classified recycling of glass, fluorescent powder, rubber lamp caps, and ferromagnetic metals through an organic combination of determined crushing and sorting processes; At the same time, the present invention has the advantages of no chemical reaction, no pollution, no wastewater or exhaust emissions, high resource utilization rate, simple process equipment, etc., and is suitable for use by fluorescent lamp tube recycling and electronic waste recycling and treatment enterprises.
