Abstract: With the rapid progress of urbanization in China， more and more domestic waste landfills were located in the urban area， which caused a large amount of land occupation， environmental pollution， and adverse effect on urban planning， which was in urgent need of treatment. Based on the overview， analysis and comparison of various treatment technologies for landfills， it was considered that the mining and Screening technology was the most suitable treatment technology for landfills with old age and high degradation stabilization degree， which could realize the landfill capacity recharge， pollution source removal， material recycling after screening， and land reuse. The comprehensive treatment project of Woqishan landfill in Wenzhou was taken as an example. According to the results of site investigation and the demand for the future land use， a suitable mining and Screening technology process for MSW landfill in southern China was proposed. The social， environmental and economic benefits obtained by using mining and Screening technology were analyzed. And the demonstration and technical support were provided for the comprehensive treatment of the same type landfills.

Key words: landfill； mining and screening； waste excavation, recycling
