| Abstract: | In the light of annual increase in the yield of municipal wastes,a new consolidation technology was used to consolidate mineral and municipal wastes.Research results demonstrate that this consolidation technology can make the pressure of municipal wastes consolidates reach more than 38 MPa.And the consolidates durability is better,such as resistance of freeze and thaw,resistance of water,resistance of dry-wet circle and resistance of sulfate erode.Heavy metals concentrations in the condensate leachate are less than identification standard for hazardous wastes of China.Heavy metals were stabilitied and solidified in the condensation. |

| Keywords: | municipal wastes consolidation technology pressure durability heavy metal ion |
