Flexible landfill is a landfill disposal facility that uses double artificial composite liners as impermeable layers. The flexible landfill area of this project is located in the southern part of the site, with a 13-layer anti-seepage structure on the ground floor and a 5-layer anti-seepage structure on the slope. It is equipped with temporary covering membrane, groundwater and leachate reverse drainage system, membrane water collection system and other facilities, and plans a flexible total storage capacity of 5.94 million m3. 

A rigid landfill is a landfill disposal facility that uses reinforced concrete as an impermeable barrier structure. The rigid landfill of this project is located on the north side of the plant, and 15 rigid reservoirs are designed with a total storage capacity of 240,000 m3, mainly disposing of hazardous wastes such as waste salt, arsenic-containing waste, and mercury-containing waste.
