Stabilizing treatment system for organic solid waste

The utility model relates to a stabilizing treatment system for organic solid waste. The stabilizing treatment system comprises a fermentation greenhouse, a drying fermentation bed, an optical-energy heat collection device, a sewage source heat pump, a heat converter and an air purification system, wherein the drying fermentation bed is arranged in the fermentation greenhouse, and the optical-energy heat collection device, the sewage source heat pump, the heat converter and the air purification system are arranged outside the fermentation greenhouse; the drying fermentation bed comprises a drying pretreatment region, a fermentative degradation region and an aging stabilization region. The stabilizing treatment system has a drying pretreatment function, is stable to work and is short in process period and good in aerobic fermentation effect, and the processed waste can be applied to direct dumping, landfill earthing, fuel utilization, soil remediation and the like.
