Abstract: The volume of small simple landfill is small. Based on site investigation, the project clearly adopted the main treatment technology of “excavation and screening + light material transport and incineration + humus soil backfilling” to clean up pollution and free up land resources. The screening scale and construction period in the process of waste 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 and the frequency of clearing and transportation. The space of the drying site can store the excavated waste for 3 days. The size of the screening workshop is determined according to the screening scale. The waste excavation area was controlled within 1 000 m2, and the construction was 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 would be needed to ensure the final utilization of the site.
