Abstract This study is to investigate the physicochemical properties for the fine fraction (particle size <15mm) of the excavated municipal solid wastes (MSWs) with fill ages ranging from 23 to 37a. The composition, physicochemical properties and leaching solution properties of the materials were measured and analyzed. The experimental results showed that the particle size ranges (2~15mm, 0.075~2mm and <0.075mm) for the materials account for 42.9%~53.9%, 40.9%~44.1% and 5.1%~13.0%, respectively. The materials can be classified as a fine-grained sand. With a increase of fill age, the characteristic particle size d₅₀ and d₁₀ decreased, the specific gravity increased greatly, and tended to be stable after 30 years. The organic matter content (18.1%~19.1%), the content of nitrogen, phosphorus and potassium, the pH of the leaching solution (7.26~8.30), and the electrical conductivity (1.08~2.51mS/cm) all met the standard of Organic media for greening. The contents of Cu, Zn, Cd, Cr and Ni in the materials exceeded the standards of Soil environmental quality Risk control standard for soil contamination of agricultural land, Planting soil for greening and Organic media for greening. The calculated value of Nemerow comprehensive pollution index was as high as 15.48~17.95, indicating the materials were heavily contaminated. It was found that the heavy metals concentrated in the fine-grained fraction with particle sizes less than 2mm. It was suggested that the fine fraction should be further screened into two parts with a particle size of 2~15mm and less than 2mm. For the part with particle size less than 2mm, the technology of microbial induced carbonate precipitation could be used to stabilize the contained heavy metals. The treated materials can be reused as a planting soil layer for landscaping, landfill closure and abandoned mine site reclamation.
