System for realizing municipal sludge reduction and resource reutilization

The utility model discloses a system for realizing municipal sludge reduction and resource recycling. The system comprises a sludge anaerobic fermentation reduction system, a sludge dehydration volumereduction system and a sludge drying carbonization resource utilization system. According to the municipal sewage treatment system, a part of excess sludge generated by the municipal sewage treatmentsystem is subjected to anaerobic fermentation, granular organic matters are decomposed, and the sludge yield is reduced from the source; adding a high-efficiency conditioning agent into the generatedsludge, and extruding and dehydrating through a volute dehydrator to realize high-efficiency volume reduction of the sludge; the dewatered sludge is carbonized at the rear end, so that the water content of the sludge is further remarkably reduced, and meanwhile, biochar with high additional value is obtained. And thus, a sewage treatment plant source sludge reduction and resource comprehensive utilization system is constru
