Abstract:

The volume of small simple landfill is small，after site investigation，it is clear that the main treatment process of'“excavation and screening + light material transportation and incineration + humus soil backfilling ” can be adopted. The screening scale and construction period in the process of garbage excavation and screening mainly depend on the ability of the back-end incineration plant to receive the light combustibles on the screen. The storage space of the recyclables is based on their proportion in the garbage and the frequency of clearing and transportation. The space of the drying site can store the excavated garbage for 3 days. The size of the screening workshop is determined according to the screening scale, and the steel structure can be used. The garbage excavation area is controlled within 1000m2, and the construction is carried out by step-by-step ( layer ) and relay excavation method. The moisture content of the waste after drying was reduced to 30~40 %, and the multi-stage high-efficiency waste comprehensive sorting equipment was used for sorting and classification. After the completion of site management, post-assessment and follow-up monitoring of the excavation area are needed to ensure the final utilization of the site.
