The Arsenic-Containing Waste Residue Disposal Project in the Realgar Mining Area of Shimen


200,000 tons

130,000 cubic meters

This project is located in Changde City, Hunan Province, and it is the most influential heavy metal pollution control project in the Yangtze River Basin. This realgar mining area has a mining history of over 1,500 years. The first phase of the project mainly involves the construction of a 130,000-cubic-meter safe landfill and the stabilization and solidification of 200,000 tons of arsenic-containing waste residue, as well as the landfill and ecological restoration of the original residue site. The second phase mainly involves transporting contaminated construction waste, sediment sludge from sewage treatment ponds, sediment at the bottom of drainage ditches, and severely contaminated soil from arsenic residue storage areas to landfills for safe disposal, and ecological restoration of the areas after transportation.
